ABSTRACT:
A door lock system includes a clutch mechanism for a lockset and has particular applicability in conjunction with lever handles. Two coupling assemblies are selectively rotatably coupled by a coupling pin. One coupling assembly is rotatably coupled to the lockset actuator. The other coupling assembly is rotatably coupled to the exterior door handle. A drive assembly includes a motor which selectively controls the position of the coupling pin to provide for the locking and unlocking functions.
