You can use an ohm meter and measure the resistance of the chip in the blade of the key. Just touch each lead on one side of the metal part of the chip and note the reading. Then match up your reading to the closest decimal reading in the box above. It should be close to one of the decimal reading in the drop down order box on this page. You can also go to any Radio Shack and have them measure the resistance for you.
Please call us for assistance at 954-905-7903 if you need help obtaining your VATS code. There is also a box below that will assist you further.
Once the key is cut, it is already programmed and it will start your vehicle. Any good hardware store can cut the key for about $2.
