An electronic lock assembly mounts to the opposite sides of a door to provide an electronically operable level of security. An electronic reader generates a signal which is employed to control the operation of a conventional latch installation. A card reader, key pad or contact activatable data port generates a signal to actuate a motor to disengage a locking dog to thereby allow rotation of the latch handle. The motor shaft is connected to a drive screw by a coil spring to permit proper operation if a jamming condition is present.
