Claim 8:
9. A lockset, comprising:
a chassis configured for mounting to a door, the chassis comprising a movable component having a locking position defining a locked state of the chassis and an unlocking position defining an unlocked state of the chassis;
a latchbolt connected with the chassis such that actuation of the chassis drives the latchbolt from an extended position to a retracted position;
an outside handle rotatably coupled with the chassis, wherein the chassis in the unlocked state is operable to be actuated by the outside handle for retraction of the latchbolt, and wherein the chassis in the locked state is inoperable to be actuated by the outside handle for retraction of the latchbolt; and
a lock cylinder operably connected with the chassis, the lock cylinder comprising a shell and a plug selectively rotatable relative to the shell upon insertion of a key;
wherein the plug is engaged with the movable component;
wherein a first rotation of the plug from a home position to a rotated position moves the movable component from the locking position to the unlocking position;
wherein a second rotation of the plug from the rotated position to the home position moves the movable component from the unlocking position to the locking position;
wherein the first rotation and the second rotation are equal and opposite rotations; and
wherein the lock cylinder is configured to prevent removal of the key from the plug when the plug is not in the home position.
