my 1994 camaro won't start and the security light blinks

Hi Chris and Thank You for your service! You probably can't avoid the dealer on this one. I'm guessing that there's a break in the wire at the ignition lock cylinder. You are going to need a dealer to handle that repair in all likelihood (if that is indeed the issue). You should have it towed there. The security system involved several other systems and needs to be handled by someone who knows what they are doing. There really is no way for an owner to disable it in the field. Good luck!
