- 1999 Buick Century Custom
My 99 Buick has a VATS key but I don't believe GM has been using that system in like 20 years. My old 2001 Chevy also had VATS. The VATS key has a specific resistance that the vehicle needs to measure in order to start. Just wondering what GM switched to after VATS? What is it called and how does it work?
