Gold VATS Keys

Gold VATS Ignition Key

VATS is a General Motors acronym that stands for Vehicle Anti-Theft System. VATS keys are distinctive because of the small, black pellet that’s embedded in the key stalk (the long part of the key).  GM made 15 different VATS keys that are visually identical, but which have pellets with different electrical resistance values. If you try to use a key with the wrong pellet, your car either won’t start or won’t run for very long.

VATS keys are sometimes known as ‘transponder keys’ because they communicate with the electronics inside the car confirming that it’s ok to start and run. Some people mistakenly confuse their key fob (the small device that remotely locks and unlocks your car and opens your trunk), with their ‘transponder key’.

If you have a VATS ignition key, you’ll need to know the electrical resistance of the pellet (in Ohms) to order the correct Gold VATS key for your car. Neither the car’s VIN, nor any codes from the key fob itself will be a substitute for this measurement. The resistance of the pellet isn’t hard to measure. A simple electrical meter will work just fine. If you don’t have a meter, you might ask a friend, a local electronics repair shop, or your local Cadillac dealer for help. The video below demonstrates the process of reading a VATS key.

Once you have measured the resistance of your current VATS ignition key, please match that value to the chart below:
