How to decode a VATS key.

VATS stands for Vehicle Anti-theft System and is also known as PASS-Key (Personal Automotive Security System). Each VATS key has a resistor embedded within the key-blade, and each resistor has 1 of 15 possible values. Sometimes the resistors are refered to as a Vats Pellet or Vats Chip. Decoding a VATS key is very simple, but it requires that you know how to use an ohm meter. Any multimeter will have an ohm meter and any Radio Shack, Electronic or Hardware Store can sell you one.

How to determine the correct vats code for your car when you lose your vats key

All 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.

Once you get your reading, match the resistance value given by your ohm meter to the resistance value, in the right column, in the chart below. The value from your ohm meter will probably not match, exactly, the resistance value in the chart below, but choose the value closest to the value on your ohm meter. The corresponding code number is the identification number of your VATS key.
