ABSTRACT:
An auxiliary switching system for vehicles having power door lock systems. The system is for use primarily when drivers lock their keys in the vehicles. The system is electronically simple, and includes a magnetically actuated switch which is mounted in a secret, exteriorly accessible location on the vehicle. A switching module is slaved to the magnetically actuated switch and is integrated into the vehicles door lock system actuation circuit. A simple magnet trips the magnetically actuated switch which, in turn, actuates the switching module which, in turn, unlocks the vehicle's door locks. Between uses, the magnet is concealed at some place on the vehicle's exterior, such as on an inside surface of a bumper, or decorative, metallic vent.
