A lock cylinder with dual driver whereby an independent drive for the dead bolt mechanism and the door latch mechanism may be achieved with a single lock so as to provide withdrawal of both the latch bolt and the dead bolt by rotation of the key inserted into the lock cylinder. The drive for the dead bolt actuating mechanism is a conventional lost motion drive extending from the rear of the cylinder assembly. In addition, a cam is coupled to the cylinder assembly threaded cap so as to provide a direct drive thereto, with a cam being coupled to the latch mechanism so that both the dead bolt and the latch bolt are retracted upon rotation of a key in the lock.
