Abstract
A lockset including a chassis having a locked state and an unlocked state, a latchbolt connected with the chassis, a handle mounted to the chassis, and a lock cylinder connected with the chassis. The handle is operable to retract the latchbolt when the chassis is unlocked, and is inoperable to retract the latchbolt when the chassis is locked. The lock cylinder includes a shell and a plug selectively rotatable relative to the shell. The chassis is configured to transition from the locked state to the unlocked state in response to rotation of the plug in a first rotational direction from a home position to a first rotated position. The chassis is configured to return from the unlocked state to the locked state in response to rotation of the plug in a second rotational direction from the first rotated position to the home position.
