Abstract: A remote control locking device is provided for a door of a motor vehicle, which consists of a remote transmitter outside of the motor vehicle for transmitting a radio signal. A receiver is carried within and is electrically connected to the electrical system of the motor vehicle for receiving the radio signal from the remote transmitter. A piston is electrically connected to the receiver and is mounted within a door jamb of the motor vehicle adjacent the side of the door. A dead bolt plunger is axially aligned with and projects outwardly from the piston for a relative lineal movement between extended and retracted positions upon operation of the remote transmitter, so that the dead bolt plunger can engage with the side to lock the door and disengage from the side to unlock the door.
