Pontiac Problems? Ask a Mechanic for Answers ASAP
Hi! Welcome to JustAnswer. I'm Ron Z and I'll be helping you with your question today.
The ignition key has a chip in it correct? Looks like a little black square with a silver chip in the center?
Do you happen to know if a by-pass was installed on this vehicle?
Ok. From what you are describing here, it sounds like the problem is in the Security System. Do you happen to have the original key that has the chip in it?
Ok. When you attempt to start the vehicle, and it shuts off with the Security light flashing, does it flash for longer than 10 seconds?
