Security on 1999 Pontiac Grand Am

At random times, the car will not start and the security light is flashing. If we wait 5-10 minutes the light goes out and the car will run. Any recomendations?

Chances are you will need to replace the ignition lock cylinder. The lock cylinder contains the security system sensor that picks up the signal that the key is in the ignition. With out the correct signal from the passlock sensor the car will not start or will start and die.
