Anti-theft Controller problems of the 1998 BMW 740

Consumer was getting out of the car when she dropped remote control key. Thinking it dropped within the vehicle closed the door, not knowing it fell between the door and the door frame. Closed the door, thinking the key was inside the vehicle. Somehow the remote security system was activated, locking and shutting down the whole electrical system, and locking the consumer in the vehicle. Consumer was unable to get out. Because the remote control was between door and door frame,it allowed a small crack between the doors, enabling the consumer to call for help. Dealer notified.
