Abstract
A motor vehicle theft protection system employs a pre-set distortion in the vehicle timing system to preclude unauthorized access to the vehicle. The system uses a key containing codes corresponding to the timing off-set. Without the codes, the timing off-set prevents operation of the vehicle.
