Abstract
A resistor coded anti-theft system particularly adapted for incorporation as original equipment on a motor vehicle is disclosed. The ignition system is defeated unless an ignition key having both the proper mechanical code and proper code resistor is used to start the vehicle. A selectively destructible fuse device is incorporated in the circuitry to permit determination of the value of the proper code resistor during a final stage of vehicle assembly.
