Abstract
A lock system for a door. The lock system includes a clutch mechanism and a lockset with a lockable latch and actuator for operating the latch. The clutch mechanism includes an input cam, an output cam, and an engagement pin having an axis and being dimensioned and configured for axial movement between a first position, in which the engagement pin engages both the input and output cams so that the input and output cams rotate synchronously, and a second position, which allows independent rotational movement of the input cam and the output cam.
