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coupled to the swinging door for rotating the swinging door to an ajar position after the doorjamb mounted deadbolt has been retracted from the locked position.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.

[ What is claimed is:] [1.] In combination with a doorjamb including a door swingable from a closed position to an open position when a manual force is applied to either side thereof, a remotely controlled door locking and opening system comprising:a deadbolt mounted to said doorjamb for locking said swinging door;an electrically activated solenoid mechanism coupled to said deadbolt, which extends and retracts said deadbolt between a locked position received within said door and an unlocked position received within said doorjamb;a motorized toothed-gear wheel mechanism received within said doorjamb, and rotatably engaging said door and having a maximum rotational velocity to produce a force sufficient to rotate said door to at least an ajar position immediately after said deadbolt has been retracted from said locked position.
