ABSTRACT:
The invention provides an electronic door lock for a door having a first side and a second side. The electronic door lock includes a locking mechanism, a credential reader, and a programmable control circuit. The locking mechanism is coupled to the door and is movable between a locked position in which the door is inhibited from opening and an unlocked position in which the door is free to open. The credential reader is coupled to the door and is operable to read a credential. The programmable control circuit is coupled to the door and is operable to move the locking mechanism between the locked position and the unlocked position at least partially in response to the read credential. The programmable control circuit is selectively programmed to move the locking mechanism to a pre-selected either one of the locked position and the unlocked position in response to a failure signal.
