Abstract: A bolt actuator is supported within a vehicle to move a dead bolt between a withdrawn or open position and an extending or locked position in response to an applied switch condition. A lock plate defining a center bore and a guide defining a similar center bore are supported in alignment between a movable vehicle door and a fixed or stationary portion of the vehicle chassis or body. The bolt actuator slides the bolt through the guide and lock plate to provide a dead bolt lock which is independent of the vehicle lock system. Embodiments are shown utilizing an electromagnetic solenoid bolt moving mechanism and a cam driven bolt moving mechanism having an electric motor drive coupled thereto.
