Abstract
A vehicle security system includes a door locking mechanism and control circuitry which prevents access to the vehicle interior unless a door lock key is used thus making it unnecessary to specifically lock the doors upon exiting the vehicle. Steering shaft lock means are also energizable by operation of the door lock key permitting elimination of the ignition key and lock cylinder.
