1994 Pontiac Firebird Security light

Does your key have a chip in it? It could be just the key, or the secuitry wire in the ignition. If it is the ignition what you have to do is replace the ignition. It is a royale pain but it only costs about $65. You will need a haynes book b/c removing the steering wheel is no fun. You can rent a puller from advanced, or buy one. The only thing that costs a lot is that the ignition does not come with a key. It comes with a key diagram and you have to go tto a dealer or other authorized key maker to have the new key made. You could see if you have any loose wires under your dash. The security wire should be gray with a yellow sticker on it running from you clomn to a wire harness.
