ABSTRACT:
A lock cylinder that includes a housing and a plug. The housing defines a cylindrical cavity, and an outer pin chamber in communication with the cavity. The plug is rotatable within the cavity, and includes a key slot, a cylindrical outer surface, and an inner pin chamber aligned with the outer pin chamber when the plug is in a locked position. An outer pin is housed in the outer pin chamber, and an inner pin is housed in the inner pin chamber. The inner pin is engageable with a key inserted into the key slot, and further engageable with the outer pin. The lock cylinder also includes a lock member in communication with the housing and the plug that selectively disables the lock cylinder in response to partial rotation of the plug from the locked position without an appropriate key in the key slot.
