     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
     Although the concepts of the present disclosure are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described herein in detail. It should be understood, however, that there is no intent to limit the concepts of the present disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives consistent with the present disclosure and the appended claims. 
     References in the specification to “one embodiment,” “an embodiment,” “an illustrative embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may or may not necessarily include that particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. It should further be appreciated that although reference to a “preferred” component or feature may indicate the desirability of a particular component or feature with respect to an embodiment, the disclosure is not so limiting with respect to other embodiments, which may omit such a component or feature. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to implement such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. 
     As used herein, the terms “longitudinal,” “lateral,” and “transverse” may be used to denote motion or spacing along three mutually perpendicular axes, wherein each of the axes defines two opposite directions. These terms are used for ease and convenience of description, and are without regard to the orientation of the system with respect to the environment. For example, descriptions that reference a longitudinal direction may be equally applicable to a vertical direction, a horizontal direction, or an off-axis orientation with respect to the environment. 
     Furthermore, motion or spacing along a direction defined by one of the axes need not preclude motion or spacing along a direction defined by another of the axes. For example, elements that are described as being “laterally offset” from one another may also be offset in the longitudinal and/or transverse directions, or may be aligned in the longitudinal and/or transverse directions. Moreover, the term “transverse” may also be used to describe motion or spacing that is non-parallel to a particular axis or direction. For example, an element that is described as being “movable in a direction transverse to the longitudinal axis” may move in a direction that is perpendicular to the longitudinal axis and/or in a direction oblique to the longitudinal axis. The terms are therefore not to be construed as limiting the scope of the subject matter described herein to any particular arrangement unless specified to the contrary. 
     Additionally, it should be appreciated that items included in a list in the form of “at least one of A, B, and C” can mean (A); (B); (C); (A and B); (B and C); (A and C); or (A, B, and C). Similarly, items listed in the form of “at least one of A, B, or C” can mean (A); (B); (C); (A and B); (B and C); (A and C); or (A, B, and C). Items listed in the form of “A, B, and/or C” can also mean (A); (B); (C); (A and B); (B and C); (A and C); or (A, B, and C). Further, with respect to the claims, the use of words and phrases such as “a,” “an,” “at least one,” and/or “at least one portion” should not be interpreted so as to be limiting to only one such element unless specifically stated to the contrary, and the use of phrases such as “at least a portion” and/or “a portion” should be interpreted as encompassing both embodiments including only a portion of such element and embodiments including the entirety of such element unless specifically stated to the contrary. 
     In the drawings, some structural or method features may be shown in certain specific arrangements and/or orderings. However, it should be appreciated that such specific arrangements and/or orderings may not necessarily be required. Rather, in some embodiments, such features may be arranged in a different manner and/or order than shown in the illustrative figures unless indicated to the contrary. Additionally, the inclusion of a structural or method feature in a particular figure is not meant to imply that such feature is required in all embodiments and, in some embodiments, may be omitted or may be combined with other features. 
     The disclosed embodiments may, in some cases, be implemented in hardware, firmware, software, or a combination thereof. The disclosed embodiments may also be implemented as instructions carried by or stored on one or more transitory or non-transitory machine-readable (e.g., computer-readable) storage media, which may be read and executed by one or more processors. A machine-readable storage medium may be embodied as any storage device, mechanism, or other physical structure for storing or transmitting information in a form readable by a machine (e.g., a volatile or non-volatile memory, a media disc, or other media device). 
     With reference to  FIG.  1   , illustrated therein is a lockset  100  according to certain embodiments. The lockset  100  generally includes an inside trim assembly  110  configured for mounting to an interior or egress side of a door, an outside trim assembly  120  configured for mounting to an exterior or non-egress side of the door, and a latch mechanism  130  connected with each of the inside trim assembly  110  and the outside trim assembly  120 , and in the illustrated form, further includes a latch spindle  108  connected between the outside trim assembly  120  and the latch mechanism  130 . 
     The inside trim assembly  110  generally includes an inside housing  112 , an inside spindle  114  rotatably mounted to the housing  112  for rotation about a longitudinal rotational axis  101  of the lockset  100 , and an inside handle  116  mounted to the spindle  114 . As described herein, the inside spindle  114  is engaged with the latch mechanism  130  such that the inside handle  116  is operable to actuate the latch mechanism  130 . In the illustrated form, the inside handle  116  is provided in the form of a lever. It is also contemplated that the inside handle  116  may be provided in another form, such as that of a knob. 
     The outside trim assembly  120  generally includes an escutcheon  122 , an outside spindle  124  rotatably mounted to the escutcheon  122  for rotation about the longitudinal axis  101 , an outside handle  126  mounted to the spindle  124 , and a lock module  200  according to certain embodiments. As described herein, the illustrated lock module  200  selectively permits the outside spindle  124  to rotate the latch spindle  108  for actuation of the latch mechanism  130  by the outside handle  126 . In the illustrated form, the outside handle  126  is provided in the form of a lever. It is also contemplated that the outside handle  126  may be provided in another form, such as that of a knob. 
     As described herein, the outside trim assembly  120  also includes a lock cylinder  140 , and may further include a control assembly  150 . Additionally or alternatively, at least a portion of the control assembly  150  may be positioned elsewhere, such as within the inside trim assembly  110  and/or at a location remote from the lockset  100 . In certain embodiments, the escutcheon  122  includes a first mounting location  129 , and the lock cylinder  140  is mounted to the first mounting location. Additionally or alternatively, the escutcheon  122  may include an alternative or second mounting location  129 ′, and a lock cylinder  140 ′ may be mounted to the second mounting location  129 ′. 
     The latch mechanism  130  generally includes a housing  132 , a latchbolt  134  mounted for movement relative to the housing  132  between an extended position and a retracted position, and at least one retractor operable to retract the latchbolt  134 . In the illustrated form, the latch mechanism  130  includes an outside retractor  136  and an inside retractor  136 ′. The outside retractor  136  is configured to engage the latch spindle  108  such that rotation of the latch spindle  108  causes retraction of the latchbolt  134 . Similarly, the inside retractor  136 ′ is configured to engage the inside spindle  114  such that rotation of the inside spindle  114  causes retraction of the latchbolt  134 . 
     In the illustrated embodiment, the latch spindle  108  and the inside spindle  114  are separate and discrete components, and are accordingly rotatable relative to one another. It is also contemplated that the latch spindle  108  and the inside spindle  114  may be integrated into a single extended spindle that extends through the latch mechanism  130  and into engagement with the lock module  200  and the inside handle  116 . In at least these forms, the latch mechanism  130  may include a single retractor  136 . 
     With additional reference to  FIGS.  2 - 5   , the lock module  200  generally includes a housing  210 , a first hub  220  rotatably mounted in the housing  210 , a second hub  230  rotatably mounted in the housing  210 , a clutch mechanism  240  operable to selectively rotationally couple the first hub  220  and the second hub  230 , an electromechanical drive assembly  250  operable to move the clutch mechanism  240  between a decoupling or locked state and a coupling or unlocked state, a first override mechanism  260  operable to move the clutch mechanism  240  to the unlocked state, and a second override mechanism  270  operable to move the clutch mechanism  240  to the unlocked state. In certain forms, the lock module  200  may further include a lock status sensor  280  operable to detect the locked/unlocked state of the clutch mechanism  240 , and thus the locked/unlocked condition of the lock module  200 . 
     The housing  210  generally includes a case  211  defining a chamber  212 , and a cover  218  configured for coupling with the case  211  to at least partially enclose various components of the lock module  200  within the chamber  212 . The cover  218  defines a first opening  219  that rotatably supports the first hub  220 , and the case  211  defines a second opening  213  that rotatably supports the second hub  230 . 
     The first hub  220  is rotatably supported by the housing  210  for rotation about a longitudinal rotational axis  201  between a first hub home position and a first hub rotated position, and generally includes a first notch  222  and a first spindle engagement feature  224 . In the illustrated form, the spindle engagement feature  224  is provided in the form of a square opening configured to engage a square portion of the outside spindle  124 . It is also contemplated that other geometries may be utilized. As one example, the opening may have a different cross-sectional geometry. As another example, the hub  220  may instead include a boss configured to be received in an opening formed in the end of the outside spindle  124 . 
     The second hub  230  is rotatably supported by the housing  210  for rotation about the longitudinal rotational axis  201  between a second hub home position and a second hub rotated position, and generally includes a second notch  232  and a second spindle engagement feature  234 . In the illustrated form, the spindle engagement feature  234  is provided in the form of a square opening configured to engage a square portion of the latch spindle  108 . It is also contemplated that other geometries may be utilized. As one example, the opening may have a different cross-sectional geometry. As another example, the hub  230  may instead include a boss configured to be received in an opening formed in the end of the latch spindle  108 , or may directly engaged the outside retractor  136 . 
     In the illustrated configuration of the outside trim assembly  120 , the first hub  220  is rotationally coupled with the outside spindle  124 , and the second hub  230  is rotationally coupled with the latch spindle  108 . It is also contemplated that this orientation may be reversed, such that the first hub  220  is rotationally coupled with the latch spindle  108 , and the second hub  230  is rotationally coupled with the outside spindle  124 . Moreover, in certain embodiments, the lock module  200  may be reversible such that each of the hubs  220 ,  230  is operable to engage each of the spindles  124 ,  108 . 
     The clutch mechanism  240  generally includes a coupler  242  having a coupling position and a decoupling position, a movable wall  243  operable to move the coupler  242  between the coupling position and the decoupling position, and a bias member  249  biasing the coupler  242  toward its decoupling position. In the illustrated form, the bias member  249  is provided in the form of a compression spring. It is also contemplated that the bias member  249  may be provided in another form, such as one including a torsion spring, an extension spring, a leaf spring, and/or one or more magnets. 
     The movable wall  243  has a locking position ( FIG.  4   ) in which the movable wall  243  permits the bias member  249  to retain the coupler  242  in its decoupling position, and an unlocking position ( FIG.  5   ) in which the movable wall  243  retains the coupler  242  in its coupling position against the urging of the bias member  249 . The movable wall  243  includes an arcuate portion  244  that maintains the coupler  242  in its coupling position as the coupled hubs  220 ,  230  cause the coupler  242  to orbit about the rotational axis  201  in response to rotation of the outside handle  136  when the lock module  200  is unlocked. The movable wall  243  also includes an engagement portion  245  engaged with a spring  259  of the electromechanical drive assembly  250 , a ledge  246  engaged with the first override mechanism  260  via a bias member  206 , a cam interface  247  through which the wall  243  is engaged with the second override mechanism  270 , and a projection  248  operable to actuate the lock status sensor  280 . 
     When the clutch mechanism  240  is in its decoupling or locked state ( FIG.  4   ), the movable wall  243  is in its locking position, and the coupler  242  is in its decoupling position. In the decoupling position, the coupler  242  is removed from at least one of the notches  222 ,  232  such that the first hub  220  is rotationally decoupled from the second hub  230 . As a result, any rotation of the outside spindle  124  is not transmitted to the latch spindle  108 , and the outside handle  126  is unable to actuate the latch mechanism  130 . This defines a locked condition of the lock module  200 , in which the lock module  200  does not permit the outside spindle  124  to rotate the latch spindle  108  for actuation of the latch mechanism  130 . 
     When the clutch mechanism  240  is in its coupling or unlocked state ( FIG.  5   ), the movable wall  243  is in its unlocking position, and the coupler  242  is in its coupling position. In the coupling position, the coupler  242  is partially received in the first notch  222  and is partially received in the second notch  232  such that the coupler  242  extends between the notches  222 ,  232 . As a result, the coupler  242  rotationally couples the hubs  220 ,  230  such that the outside handle  126  is operable to actuate the latch mechanism  130 . This defines an unlocked condition of the lock module  200 , in which the lock module  200  rotationally couples the outside spindle  124  with the latch spindle  108 . 
     In the illustrated form, the lock mechanism of the lock module  200  is provided in the form of a clutch mechanism  240 , which selectively permits the outside spindle  124  to rotate the latch spindle  108  by selectively coupling the first hub  220  with the second hub  230 . It is also contemplated that the lock module  200  may selectively permit the outside spindle  124  to rotate the latch spindle  108  in another manner. For example, the hubs  220 ,  230  may be at all times rotationally coupled, and a lock mechanism according to certain embodiments may selectively prevent rotation of the coupled hubs  220 ,  230  to thereby selectively prevent the outside spindle  124  from rotating the latch spindle  108 . 
     As should be evident from the foregoing, the locked/unlocked state of the lock module  200  corresponds to the coupling/decoupling state of the clutch mechanism  240 . Additionally, the coupling/decoupling state (or the locking/unlocking state) of the clutch mechanism  240  corresponds to the coupling/decoupling position of the coupler  242 , which in turn depends upon the locking/unlocking position of the movable wall  243 . Thus, the lock module  400  can be moved between its locked state and its unlocked state by moving the movable wall  243  between its locking position and its unlocking position. As described herein, each of the electromechanical drive assembly  250 , the first override mechanism  260 , and the second override mechanism  270  is operable to move the wall  243  to its unlocked position such that the lock module  200  can be unlocked by each and any of the electromechanical drive assembly  250 , the first override mechanism  260 , and the second override mechanism  270 . 
     The electromechanical drive assembly  250  is operable to transition the lock module  200  between its locked state and its unlocked state in response to a lock/unlock signal, and includes an electrically-operable driver. In the illustrated form, the electrically-operable driver is provided in the form of an electromechanical driver, and more particularly is provided in the form of a rotary motor  252 . The motor  252  includes an output shaft  253  that is operable to rotate a spring  254  via a gear train  256  to thereby move the wall  243  between its locked position and its unlocked position. It is also contemplated that the electrically-operable driver may take another form operable to move the wall  243  between its locked position and its unlocked position. For example, the driver  252  may be provided in the form of a linear motor, a linear solenoid, a rotary solenoid, or an electromagnet. 
     In the illustrated embodiment, the spring  254  is provided as a coil spring, and the engagement portion  245  of the wall  243  is positioned between adjacent coils of the spring  254 . As a result, rotation of the spring  254  in a locking direction urges the wall  243  toward its locking position, and rotation of the spring  254  in an unlocking direction opposite the locking direction urges the wall  243  toward its unlocking position. Such rotation of the spring  254  in opposite directions may be effected by causing the motor  252  to rotate the shaft  253  in opposite directions. In response to receiving a lock signal, the motor  252  may rotate the motor shaft  253  in a first direction to thereby rotate the spring  254  in its locking direction, thereby urging the wall  243  toward its locking position. In response to receiving an unlock signal, the motor  252  may rotate the motor shaft  253  in a second direction opposite the first direction to thereby rotate the spring  254  in its unlocking direction, thereby urging the wall  243  toward its unlocking position. In the illustrated form, the lock/unlock signal is transmitted by a control assembly external to the lock module  200 , such as a control assembly  150  mounted in the escutcheon  122 , a control assembly of the inside trim assembly  110 , and/or a remote control assembly. In other embodiments, the lock/unlock signal may be transmitted by a control assembly internal to the lock module  200 . 
     With additional reference to  FIGS.  6  and  7   , the first override mechanism  260  is operable to unlock the lock module  200 , and in the illustrated embodiment is provided in the form of an override plate  262  including a cam slot  264  and a ledge  266 . The cam slot  264  is configured to interface with a cam  148  such that rotation of the cam  148  causes the plate  262  to translate between a deactuated position ( FIG.  6   ) and an actuated position ( FIG.  7   ). Translation of the plate  262  from the deactuated position to the actuated position causes the override mechanism  260  to urge the wall  243  toward its unlocked position. More particularly, the ledge  266  of the override mechanism  260  is engaged with the ledge  246  of the wall  243  such that actuating movement of the plate  262  urges the wall  243  toward its unlocking position. Thus, the first override mechanism  260  is operable to unlock the lock module  200  even when the electromechanical drive assembly  250  has not been actuated and/or is under a power failure condition. As described herein, in certain embodiments, the cam  148  is operably connected with a plug  144  of a lock cylinder  140  such that the lock module  200  is capable of being unlocked via actuation of the lock cylinder  140 . 
     With additional reference to  FIGS.  8 - 11   , the second override mechanism  270  is operable to unlock the lock module  200 , and in the illustrated embodiment is provided in the form of an override cam  272  including a receiving slot  274  and a cam interface  276  operable to engage the cam interface  247  of the wall  243 . The receiving slot  274  is configured to receive a tailpiece of a lock cylinder such that actuation of the lock cylinder rotates the override cam  272  between a home position ( FIGS.  8  and  9   ) and a rotated position ( FIGS.  10  and  11   ). As described herein, such rotation of the override cam  272  from the home position to the rotated position urges the wall  243  from its locked position to its unlocked position, thereby unlocking the lock module  200 . 
     With the override cam  272  in its home position ( FIGS.  8  and  9   ), the override cam interface  276  permits movement of the wall cam interface  247  such that the wall  243  is free to move between its locked and unlocked positions (e.g., under the urging of the electromechanical drive assembly  250  and/or the first override mechanism  260 ). Thus, when the override cam  272  is in its home position, the lock module  200  is free to lock and unlock as normal. During rotation of the override cam  272  toward its rotated position, a ramp  277  of the cam interface  276  engages a corresponding ramp of the wall cam interface  247 , thereby urging the wall  243  toward its unlocked position and unlocking the lock module  200 . Thus, when the override cam  272  is in its rotated position ( FIGS.  10  and  11   ), the lock module  200  is unlocked. The second override mechanism  270  is therefore operable to unlock the lock module  200  even when the electromechanical drive assembly  250  has not been actuated and/or is under a power failure condition. 
     The lock status sensor  280  is operable to detect the locked/unlocked state of the lock module  200 , and in the illustrated form comprises a snap action switch  281  including a body portion  282  and an actuation arm  284 . Those skilled in the art will readily recognize that snap action switches such as the switch  281  have a default state (i.e., one of an open state or a closed state) when the arm  284  is in a home position, and a non-default state (i.e., the other of the open state or the closed state) when the arm  284  is in a depressed position. In the illustrated form, the projection  248  of the wall  243  is configured to depress the arm  284  when the wall  243  is in its locking position ( FIGS.  8  and  9   ), and to allow the arm  284  to return to its home position when the wall  243  is in its unlocking position ( FIGS.  10  and  11   ). As a result, the locking/unlocking position of the wall  243  (and thus the locked/unlocked state of the lock module  200 ) can be determined based upon the default/non-default state of the switch  281 . 
     While the illustrated lock status sensor  280  is provided in the form of a mechanical snap action switch  281 , it should be appreciated that the lock status sensor  280  may take another form. As one example, the sensor  280  may be a magnetically-actuated sensor, such as a reed switch or a Hall effect sensor. Moreover, while the illustrated switch  281  is positioned to be in its default state when the lock module  200  is unlocked and to be in its non-default state when the lock module  200  is locked, it should be appreciated that this configuration may be reversed such that the switch  281  is in its default state when the lock module  200  is locked, and is in its non-default state when the lock module  200  is unlocked. 
     With additional reference to  FIGS.  12  and  13   , the lock module  200  is configured for use with a lock cylinder  140 , and has a first configuration ( FIG.  12   ) and a second configuration ( FIG.  13   ). The lock cylinder  140  is operable by a key  141 , and generally includes a shell  142 , a plug  144  mounted in the shell  142  for rotation about a rotational axis  145 , and a tumbler assembly operable to selectively prevent rotation of the plug  144  relative to the shell  142 . The tumbler assembly is biased toward a blocking position, in which the tumbler assembly prevents rotation of the plug  144  relative to the shell  142 . When the proper key  141  is inserted into the plug  144 , the tumbler assembly moves to an unblocking position, in which the tumbler assembly does not prevent rotation of the plug  144  relative to the shell  142 . 
     With the lock module  200  in the first configuration ( FIG.  12   ), the plug  144  is operably connected with a cam  148 , which includes a post  149  that projects into the cam slot  264  of the first override mechanism  260 . Thus, when the lock module  200  is in its first configuration, the lock cylinder  140  is engaged with the first override mechanism  260  such that actuation of the lock cylinder  140  unlocks the clutch mechanism  240  as described above with reference to  FIGS.  6  and  7   . In the first configuration, the rotational axis  145  of the plug  144  extends longitudinally, or in a direction defined by the longitudinal rotational axis  201  of the hubs  220 ,  230 . In the illustrated form, the rotational axis  145  is parallel to the rotational axis  201  when the lock module  200  is in its first configuration. It is also contemplated that the rotational axes  145 ,  201  may be askew to one another when the lock module  200  is in its first configuration. 
     With the lock module  200  in the second configuration ( FIG.  13   ), the plug  144  is operably connected with a tailpiece  146 , which extends into the receiving slot  274  of the second override mechanism  270 . Thus, when the lock module  200  is in its second configuration, the lock cylinder  140  is engaged with the second override mechanism  270  such that actuation of the lock cylinder  140  unlocks the clutch mechanism  240  as described above with reference to  FIGS.  8 - 11   . In the second configuration, the rotational axis  145  of the plug  144  extends in a direction transverse to the longitudinal rotational axis  201  of the hubs  220 ,  230 . In the illustrated form, the rotational axis  145  is perpendicular to the rotational axis  201  when the lock module  200  is in its second configuration. It is also contemplated that the rotational axes  145 ,  201  may be askew to one another when the lock module  200  is in its second configuration. 
     As should be evident from the foregoing, the lock module  200  has a first configuration in which the lock cylinder  140  is engaged with the first override mechanism  260 , and a second configuration in which the lock cylinder  140  is engaged with the second override mechanism  270 . Moreover, the lock cylinder  140  has a different orientation when the lock module  200  is in the first configuration as compared to when the lock module  200  is in the second configuration. More particularly, the rotational axis  145  has a first orientation when the lock module  200  is in the first configuration and a second orientation when the lock module  200  is in the second configuration, and the first orientation and the second orientation of the rotational axis  145  are transverse to one another. Additionally, the lock module  200  is operable to transition between the first configuration and the second configuration without opening the housing  210 . 
     In the illustrated form, the first configuration is one in which a lock cylinder  140  is engaged with the first override mechanism  260  and no lock cylinder is engaged with the second override mechanism  270 , and the second configuration is one in which a lock cylinder  140  is engaged with the second override mechanism  270  and no lock cylinder is engaged with the first override mechanism  260 . It is also contemplated that the lock module  200  may have an additional or alternative configuration in which a first lock cylinder is engaged with the first override mechanism  260  and a second lock cylinder is engaged with the second override mechanism  270 . In such forms, the first lock cylinder and the second lock cylinder may be keyed alike, or may be keyed differently. 
     With additional reference to  FIG.  14   , illustrated therein is a product line  300  according to certain embodiments. The product line  300  generally includes a first assembly  310  and a second assembly  310 ′, each of which is configured for use with the lock module  200 . As a result, the product line  300  may be utilized to create each of a first product configuration  320  and a second product configuration  320 ′. As described herein, the first product configuration  320  includes the lock module  200  and the first assembly  310 , and the second product configuration  320 ′ includes the lock module  200  and the second assembly  310 ′. 
     In the illustrated embodiment, the first product configuration  320  is provided along the lines of the lockset  100  illustrated in  FIG.  1   . More particularly, the first product configuration  320  includes the lock module  200  and the first assembly  310 , which generally includes a first outside trim assembly  120  and a first latch mechanism  130 , and which may further include an inside assembly along the lines of the inside trim assembly  110 . The first outside trim assembly  120  includes a first lock cylinder  140  and a first control assembly  150 . The first outside trim assembly  120  may further include a cam  148  coupled to a plug  144  of the lock cylinder  140 . As described herein, installing the lock module  200  to the first assembly  310  may involve engaging the first spindle  124  with the first hub  220 , engaging the first lock cylinder  140  with the first override mechanism  260 , and placing the electromechanical drive assembly  250  in communication with the first control assembly  150 . 
     In the illustrated form, the second product configuration  320 ′ is substantially similar to the first product configuration  320 , and similar reference characters are used to denote similar elements and features. For example, the second product configuration  320 ′ includes the lock module  200  and the second assembly  310 ′, which generally includes a second outside trim assembly  120 ′ and a second latchbolt mechanism  130 ′, and which may further include a second inside assembly along the lines of the inside trim assembly  110 . As with the above-described outside trim assembly  120 , the second outside trim assembly  120 ′ includes a second lock cylinder  140 ′ and a second control assembly  150 ′. As described herein, installing the lock module  200  to the second assembly  310 ′ may involve engaging the second spindle  124 ′ with the first hub  220 , engaging the second lock cylinder  140 ′ with the second override mechanism  260 , and placing the electromechanical drive assembly  250  in communication with the second control assembly  150 ′. 
     As noted above, the illustrated second outside trim assembly  120 ′ is substantially similar to the first outside trim assembly  120 . One distinction between the two outside assemblies  120 ,  120 ′ (and thus between the two assemblies  310 ,  310 ′ and between the two product configurations  320 ,  320 ′) is the position and/or orientation of the lock cylinders  140 ,  140 ′. The first outside trim assembly  120  includes a first lock cylinder mounting location  129 , and the second outside trim assembly  120  includes a second lock cylinder mounting location  129 ′ different from the first lock cylinder mounting location  129 . When the first lock cylinder  140  is mounted to the first mounting location  129 , the rotational axis  145  of the plug  144  of the first lock cylinder extends longitudinally, or in a direction defined by the longitudinal rotational axis  101  about which the first outside spindle  124  is rotatable. When the second lock cylinder  140 ′ is mounted to the second mounting location  129 ′, the rotational axis  145 ′ of the plug  144 ′ of the second lock cylinder  140 ′ extends in a direction transverse to the longitudinal rotational axis  101 ′ about which the second outside spindle  124 ′ is rotatable. 
     With additional reference to  FIG.  15   , an exemplary process  400  that may be performed using the product line  300  is illustrated. Blocks illustrated for the processes in the present application are understood to be examples only, and blocks may be combined or divided, and added or removed, as well as re-ordered in whole or in part, unless explicitly stated to the contrary. While the blocks are illustrated in a relatively serial fashion, it is to be understood that two or more of the blocks may be performed concurrently or in parallel with one another. Moreover, while the process  400  is described herein with specific reference to the product line  300  illustrated in  FIG.  14   , it is to be appreciated that the process  400  may be performed with product lines having additional and/or alternative features. 
     In certain embodiments, the process  400  may begin with a providing procedure  410 . As described herein, the providing procedure  410  may include one or more of providing a first assembly in block  412 , providing a second assembly in block  414 , and/or providing a lock module in block  416 . 
     The procedure  410  may include block  412 , which generally involves providing a first assembly. The first assembly provided in block  412  may include one or more of a first escutcheon, a first spindle rotatable about a first longitudinal axis, a first latchbolt mechanism, a first lock cylinder mounted to a first mounting location and having a first rotational axis, and/or a first control assembly. For example, block  412  may involve providing the first assembly  310  of the product line  300 , which generally includes a first escutcheon  122 , a first spindle  124  rotatable about a first longitudinal axis  101 , a first latch mechanism  130 , a first lock cylinder  140  mounted to a first mounting location  129  and having a first rotational axis  145 , and/or a first control assembly  150 . In the illustrated form, the first rotational axis  145  extends longitudinally in a direction defined by the first longitudinal axis  101 . 
     The procedure  410  may include block  414 , which generally involves providing a second assembly. The second assembly provided in block  412  may include one or more of a second escutcheon, a second spindle rotatable about a second longitudinal axis, a second latchbolt mechanism, a second lock cylinder mounted to a second mounting location and having a second rotational axis, and/or a second control assembly. For example, block  414  may involve providing the second assembly  310 ′ of the product line  300 , which generally includes a second escutcheon  122 ′, a second spindle  124 ′ rotatable about a second longitudinal axis  101 ′, a second latchbolt mechanism  130 ′, a second lock cylinder  140 ′ mounted to a second mounting location  129 ′ and having a second rotational axis  145 ′, and/or a second control assembly  150 ′. In the illustrated form, the second rotational axis  145 ′ extends in a direction transverse to the second longitudinal axis  101 ′. Additionally, when the longitudinal axes  101 ,  101 ′ are arranged parallel to one another, the rotational axes  145 ,  145 ′ extend transverse to one another. 
     The procedure  410  may include block  416 , which generally involves providing a lock module configured for installation to each of the first assembly and the second assembly. For example, block  416  may involve providing the lock module  200 , which is configured for installation to each of the first assembly  310  and the second assembly  310 ′. The lock module provided in block  416  may include an electrically-operable driver, a first override mechanism, a second override mechanism, and a lock mechanism operable to be unlocked by each and any of the driver, the first override mechanism, and the second override mechanism. For example, the lock module  200  includes an electromechanical driver  252 , a first override mechanism  260 , a second override mechanism  270 , and a lock mechanism  240  operable to be unlocked by each and any of the electromechanical driver  252 , the first override mechanism  260 , and the second override mechanism  270 . 
     In certain forms, the electromechanical driver may be configured to urge the lock mechanism toward a locked state in response to a lock signal, and to urge the lock mechanism toward an unlocked state in response to an unlock signal. For example, the electromechanical driver  252  is configured to urge the lock mechanism  240  toward a locked state in response to a lock signal, and to urge the lock mechanism  240  toward an unlocked state in response to an unlock signal. In such forms, one or both of the first control assembly provided in block  412  and/or the second control assembly provided in block  214  may be operable to transmit a lock/unlock signal that selectively comprises the lock signal and the unlock signal. For example, each of the first control assembly  150  and the second control assembly  150 ′ is operable to transmit a lock/unlock signal that selectively comprises the lock signal and the unlock signal. 
     The process  400  may include a selection procedure  420 , which generally involves receiving selection of a product configuration from a plurality of product configurations, the plurality of product configurations comprising a first product configuration and a second product configuration. For example, the selection procedure  420  may involve receiving a user&#39;s selection of a selected product configuration from a plurality of product configurations including the first product configuration  320  and the second product configuration  320 ′. In various forms, block  420  may be performed in person (for example at an assembly center), or may be performed remotely (such as via the internet or another communication network). 
     The process  400  may include a first assembly procedure  430 , which generally involves selectively installing the lock module to the first assembly to thereby create a first product configuration. For example, the procedure  430  may involve installing the lock module  200  to the first assembly  310  to thereby create the first product configuration  320 . In certain forms, the first assembly procedure  430  may be performed in response to receiving selection of the first product configuration in block  420 . 
     The first assembly procedure  430  may include block  432 , which generally involves installing the lock module to a first escutcheon of the first assembly. For example, block  432  may involve installing the lock module  200  to the first escutcheon  122 . The procedure  430  may include block  434 , which generally involves engaging a first lock cylinder of the first assembly with a first override mechanism of the lock module. For example, block  434  may involve engaging the first lock cylinder  140  with the first override mechanism  260  by inserting the post  149  of the cam  148  into the cam slot  264  of the override plate  262 . The procedure  430  may include block  436 , which generally involves placing an electromechanical driver of the lock module in communication with a first controller of the first assembly such that the first controller is operable to transmit a lock/unlock signal to the electromechanical driver. For example, block  436  may involve placing the electromechanical driver  252  in communication with a first controller  152  of the first assembly  310  such that the first controller  152  is operable to transmit a lock/unlock signal to the electromechanical driver  252 . 
     The process  400  may include a second assembly procedure  440 , which generally involves selectively installing the lock module to the second assembly to thereby create a second product configuration. For example, the procedure  440  may involve installing the lock module  200  to the second assembly  310 ′ to thereby create the second product configuration  320 ′. In certain forms, the second assembly procedure  440  may be performed in response to receiving selection of the second product configuration in block  420 . 
     The second assembly procedure  440  may include block  442 , which generally involves installing the lock module to a second escutcheon of the second assembly. For example, block  442  may involve installing the lock module  200  to the second escutcheon  122 ′. The procedure  440  may include block  444 , which generally involves engaging a second lock cylinder of the second assembly with a second override mechanism of the lock module. For example, block  444  may involve engaging the second lock cylinder  140 ′ with the second override mechanism  270  by inserting the tailpiece of the second lock cylinder  140 ′ into the receiving slot  274  of the override cam  272 . The procedure  440  may include block  446 , which generally involves placing the electromechanical driver of the lock module in communication with a second controller of the second assembly such that the second controller is operable to transmit a lock/unlock signal to the electromechanical driver. For example, block  446  may involve placing the electromechanical driver  252  in communication with a second controller  152 ′ of the second assembly  310 ′ such that the second controller  152 ′ is operable to transmit a lock/unlock signal to the electromechanical driver  252 .
