A door locking system including a plurality of doors each having a mechanical key operated door lock, each door lock including a lock cylinder including a lock body defining an elongate bore, a tumbler rotatably mounted in the elongate bore of the lock body and having a keyway, and a pin assembly associated with the tumbler and with the lock body for preventing rotation of the tumbler with respect to the lock body other than when a correctly configured key is placed in the keyway, an electrical rotation sensor sensing rotation of the tumbler in the keyway and providing a tumbler rotation electrical output in response thereto, and an electromechanical interlock which, notwithstanding rotation of the tumbler of the lock cylinder, permits actuation of the door lock only upon receipt of an auxiliary signal. |
