One common cause for the security light to come on is the chip in the GM ignition key. First try the spare (if you have it) if that does not work it may be the contacts inside the ignition. I am not sure if it can be repaired or if the ignition must be replaced. I have heard that the problem can escalate to cutting out the motor, so it is not something to be ignored. If your ignition key does not have a black piece of rubber with a small piece of metal in it, just disregard what I said. I hope that this information will help you get to the bottom of the problem.
