GM “No Start” Anti-Theft Systems & Diagnostics
Did you know Passlock was standard equipment on 1996 and up Cavaliers and Sunfires?
General Motors first introduced (VATS), an anti-theft system, which proved to reduce vehicle theft in 1986 on Corvette models. Vehicle theft has increased since the original VATS system, and as a result, various anti-theft systems have been installed on most GM vehicles since then. The original VATS have changed and there are five different systems that have been used over the years.
