Claim 21:
22. The method of claim 16, wherein the lockset further comprises a chassis connected with the handle and the latchbolt;
wherein the chassis comprises a keycam assembly, the keycam assembly comprising:
a keycam shell defining a cam aperture, wherein rotation of the shell from a shell home position to a shell rotated position retracts the latchbolt;
a lock control lug movably mounted in the keycam shell, the lock control lug having an unlocking position in which the lock control lug permits rotation of the keycam shell by the handle, the lock control lug having a locking position in which the handle is inoperable to rotate the keycam shell;
a cam follower rotationally coupled with the plug and longitudinally coupled with the lock control lug, wherein a portion of the cam follower is received in the cam aperture; and
a spring engaged with the cam follower;

wherein transitioning the lockset from the locked state to the unlocked state comprises causing the spring to urge the lock control lug from the locking position to the unlocking position in response to rotation of the plug from the home position to the first rotated position in the first rotational direction; and
wherein transitioning the lockset from the unlocked state to the locked state comprises causing an edge of the cam aperture to drive the cam follower against an urging of the spring to an unlock-setting position in response to rotation of the plug from the first rotated position to the home position in the second rotational direction, thereby driving the lock control lug from the unlocking position to the locking position.
