Not a typical day getting called out to make a key for a 1996 Cadillac Hearse with a Vehicle Anti-theft System (VATS ) key system.

General Motors invented and deployed the VATS system into their vehicles in attempt to hinder auto thieves.

VATS (Vehicle Anti Theft System) was introduced by GM on the 1986 Corvette because the Corvette had become the number one target of car thieves. Corvette thefts dropped so impressively after VATS was implemented that GM expanded the system in 1988 to the Camaro, Firebird, and Cadillac Seville. VATS was standard equipment on all Cadillac vehicles and on many other Chevrolet, Pontiac, Buick, and Oldsmobile vehicles.

Each VATS key has a resistor embedded within the key-blade, and each resistor has 1 of 15 possible values. Decoding a VATS key is simple but it requires that you use an ohm meter.

VATS keys have a resistor embedded in the key blade with metal prongs protruding out of each side of the key blade. In order to read the resistance of the resistor in the key blade, place one lead of the ohm meter on one metal prong, and the other lead on the other metal prong, opposite, on the other side of the key blade. With the leads in there proper position a resistance value can be read from the ohm meter.

The black plastic pellet in the blade of the key contains a simple resistor, not a computer. There are 15 resistor values in the VATS system for 6 cut and 10 cut GM Keys.

Tamper: This mode happens when the wrong resister key or mechanical key for the vehicle is cranked and the resistance value as seen by the module is not the same as the value stored in the module. When this happens the module shuts down and the car will not start for the 4 minute “time-out”. The security light will also illuminate for the 4 minutes. The Start Enable Relay will not energize and the Fuel Enable signal will not be sent. After the “time-out” and the correct key and resistor is inserted the car will start.
