ABSTRACT:
A door locking system for child-safety door locking systems on an automobile door including a latch and a door lock mechanism. The door handle is incapable of unlatching the door when the locking mechanism locks the latch. The locking system includes a door panel having an opening for receiving a lock button mounted on a lock rod connected to the locking mechanism and movable between locked and unlocked positions. A shield is movable within the opening relative to the lock button and door panel between a retracted inoperative position corresponding to a normal lock mode in which the shield is recessed in the opening for accessing the lock button for moving the lock button between its locked and unlocked positions, and an extended operative position corresponding to a guard lock mode in which the shield extends outward of the opening to shield the lock button in its locked position to prevent access to the lock button for manual movement to its unlocked position. A key lock is operatively connected to the shield for selectively moving the shield between its inoperative and operative positions.
