ABSTRACT:
A wireless, remotely controlled door locking and opening system includes a door swingable from a closed position to an open position when a manual force is applied to either side thereof. A solenoid controlled deadbolt is mounted to the doorjamb for locking the swinging door. A motorized toothed-gear wheel mechanism is rotatably coupled to the swinging door for rotating the swinging door to an ajar position after the doorjamb mounted deadbolt has been retracted from the locked position. The deadbolt solenoids and the gear wheel motor are selectively activated with a remote control means.
