Abstract
An electronic lock mechanism includes a solenoid driven actuator and a cam actuator ring. The cam ring interfaces with both the latch of a door lock and the door lock key cylinder. With this interfacing, the door latch can be independently operated by one of the key cylinder, the cam actuator ring or a door lock push bar or paddle. With this independent operation, the ability to open a door can be maintained during power or lock mechanism failures for purpose of egress from the area secured by the door lock.
