They introduced a Vehicle Anti-Theft System (VATS) key that had a transponder in the key's head that was linked to the vehicle's immobiliser. The VATS key was an effective protection against auto theft and it functioned by sending a signal to the car's onboard computer. The computer then compared the signal with a previously stored code and, in the event that the key was not connected to the immobiliser, it might not start the engine.
