1. A lockset, comprising:
a chassis configured for mounting to a door, the chassis having a locked state and an unlocked state;
a latchbolt connected with the chassis such that the chassis is operable to retract the latchbolt;
an outside handle rotatably coupled with the chassis, wherein the chassis in the unlocked state is configured to permit the outside handle to retract the latchbolt, and wherein the chassis in the locked state is configured to prevent the outside handle from retracting 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;
wherein upon insertion of a proper key into the plug, the plug is operable to rotate in a first rotational direction from a home position to a first rotated position, and to rotate from the first rotated position to the home position in a second rotational direction opposite the first rotational direction;
wherein the chassis is configured to transition from the locked state to the unlocked state in response to rotation of the plug in the first rotational direction from the home position to the first rotated position;
wherein the chassis is configured to return from the unlocked state to the locked state in response to rotation of the plug in the second rotational direction from the first rotated position to the home position; and
wherein the lock cylinder is configured to retain the key within the plug when the plug is in the first rotated position.
