How do you reset security system on 1998 Pontiac Bonneville?
how do i restate my security system in my 2000 Bonneville
How do you disengage or reset the security system on a 92 Pontiac Bonneville when neither key works which causes the car not to start?
I am not sure about the mercury sable but my car does that also, 2003 Pontiac grand am gt, it tells you how to reset in owners manual. I have to turn the key to the on position, wait about 10 minutes and the security light in the dash starts blinking, when that happens...turn the key off and try to start it. Hope this helps
