A remote control lock utilizes a low-power control circuit and a solenoidactuated mechanism which is incorporated into the existing structure of a manual lock without affecting the manual locking capabilities. In one embodiment, a known locking lug structure is modified by providing an annular ring thereon which permits shifting of the locking lug by a camming mechanism connected to the solenoid. In a second embodiment, a movable locking pin is retractable, upon actuation by a solenoid, to permit rotation of the lock spindle and thus override manual locking. A transmitter is provided for radio-frequency transmission of a rolling code from a compact assembly which may be mounted on a key chain. A battery-powered receiver is equipped with power-saving features and provided with a rolling code decoder/controller.
