Override Anti-Theft Lock on 2002 Chevy Cavalier


Asked by Jul 28, 2016 at 11:17 AM about the 2002 Chevrolet Cavalier Base Coupe

Question type: Maintenance & Repair

Bought a beater car just to get from Illinois to Texas, took out the passenger
seat for more cargo room, went to start the engine and the Theft System light
came on and it wouldn't even try to start. Tried several crazy work arounds
from the internet -- turned ignition on, pressed the gas for 60 seconds, off for
60, unlocked door with the original key, left then right, then left again,
unplugged battery, plugged back in... nothing. Battery had corrision, so put a
new battery in, still nothing. Any ideas? Anyone with similar experience on
unlocking the "Theft System" in a 2002 Cavalier??? Any help is greatly

Don't really know why removing the seat would trigger the security system. If you clipped some wires that might have done it. HTH. -Jim
