Remote control deadlock bolt for cars

A remote control locking device for a door of a motor vehicle which comprises:

• a) a remote transmitter outside of the motor vehicle for transmitting a radio signal;
• b) a receiver carried within and electrically connected to an electrical system of the motor vehicle for receiving the radio signal from said remote transmitter;
• c) a piston electrically connected to said receiver and mounted within a door jamb of the motor vehicle adjacent a side of the door;
• d) a dead bolt plunger axially aligned with and projecting outwardly from said piston for a relative lineal movement between extended and retracted positions upon operating of said remote transmitter, so that said dead bolt plunger can engage with the side to lock the door and disengage from the side to unlock the door;
• further including immobilizing means for simultaneously immobilizing a door opening mechanism of the door of the motor vehicle;
• wherein said immobilizing means includes:
• e) the door opening mechanism being a key operated door lock cylinder in the door, having a tab projecting from its side;
• and
• f) a vertical rod mounted within the side of the door to slide therein, said vertical rod having a lower beveled end to contact the distal end of said dead bolt plunger, so that when said dead bolt plunger is in its extended position, said vertical rod will slide upward with an upper end of said vertical rod engaging said tab preventing the door lock cylinder from turning.
