VAT is an acronym for Vehicle Anti-theft System. It is usually referred to as a pass key which stands for (Personal Automotive Security System) and is a security feature adopted by several different GM model vehicles from 1986 to 2005. Every VATS key produced with a unique resistor on the key blade and possesses a possible codes of 1 out of 15 values. By assigning a vats key with the correct resister pellet, the driver inserts the key blade into the ignition lock, which then make a contact with the resister pellet on the key so the electronic VATS system can reads its value. If the key has a match resister pellet, then the car will start, otherwise, then the engine will be disabled.

2. The resister is protrudes out on both sides of the blade and the resister pellet function the same on a single sided or double sided vats key.
3. To buy the correct key, a driver must know the right VATS code. This code cannot be programmed, configured or changed. Replacing the ignition switch for a VATs equipped vehicle does not change the code, since the code for a particular vehicle determined by the electronics and not by the ignition.
4. 10 cut VATs keys and vehicles that was manufactured since 1990 can only use codes 2 through 15.
5. 6 cut VATs keys uses codes 1 through 15.
