Automotive Anti-Theft Keys

As you may already know, many of today's automobiles incorporate high security measures into their keys. You may have already encountered this when attempting to have a key duplicated; only to discover that you're newly cut key would not start the vehicle.

It all started with the Chevy Corvette. Since 1986, the ignition key uses a "chip" imbedded in the blade, which must match the value stored in the onboard computer of the vehicle. Without the correct key, the vehicle is disabled.

This one has a visible resister pellet embedded in the blade.


Since then, another anti-theft technology has emerged as a favorite for auto manufacturers. These units are called Transponders. The electronics involve a two-way communication between the key and computer of the vehicle, and if this link does not exist, the vehicle is disabled. An example of these is the Ford Taurus sedan, manufactured since 1996. A person has to have 2 keys just to have a duplicate key made, unless you have the special equipment we have.

Your vehicle may contain an anti-theft element without you even knowing it. Transponders are molded inside the head of the key where you would not notice it. It is termed a passive anti-theft method, as the security requires no action by the vehicle operator.


Other forms of passive theft deterrent include MRD (a magnet embedded in the ignition cylinder that creates a measurable "Halls effect" when the proper key is rotated in the lock), and MATS (a steel plate in the steering column). There is nothing special about the keys in these two setups, as they are mechanical obstacles to deter a forced ignition attempt.

Listed below are some of the manufactures that have designed a particular anti-thief device within the key blank and /or the computer of the vehicle:

                 *Jaguar       *Kia          *Chrysler      *Mitsubishi
