Generally, seeing the blinking security light to the left of steering wheel on your Pontiac Grand Prix, or GP, is comforting. Sometimes, however, problems arise to make the security system seem like more of a hassle than a helpful feature.
When your Grand Prix starts and functions properly, you will see the security light flashing only after you get out of the car and lock it. The security system, however, also may indicate issues regarding your car's key and ignition.
Perhaps your car's engine shuts off roughly three seconds after you turn it on, or maybe it will not start. If the security light blinks, chances are good that the Grand Prix security system created the problem.
The first way to try to solve the problem is to use a spare ignition key. A key's microchip often wears out, causing the security system to reject the key. If that doesn't work, rotate the key in the ignition to the "On" position, and wait until the security light disappears. Then turn the key to the "Accessories" position and then to the "Off" position. You also could try to bypass the security system by installing a relay. If none of those methods work, consult a Pontiac dealership.
