I have a 2000 Pontiac Grand prix GTP with the anti-theft system. When I start my car, the security system light will flash and the car will shut off . After turning the ignition on 6-7 times it will start and the light will stop flashing. The remote for the car won't work..it won't open the doors or lock them so I tried re-programming it, but it didn't do any good. It acts like it is being stolen, like the safety feature is on alert. I have looked in the manual, but it is very vague about the problem. They want to charge me $90 bucks at the dealer just to look at it. So If anyone knows what can be the problem..please help. I would love to get my remote unlock and lock to work too.I just got this car so I know very little about it, but I am trying!
