1 Answer


You need an original VATS (Vehicle Anti Theft System) key. There were 15 different keys available for your car. Each has a visible "chip" on the key shank. This is a resistor block that is matched to the vehicle. If no keys are available you'll have to find out which of the 15 possibilities your car needs. Then have a VATS key blank cut to fit the ignition lock cylinder. HTH. -Jim
