There is like an antitheft device/key/chip that is found underneath the steering wheel/column on my 95 gt. Its about one inch wide and 1 and a 1/2 inches long along with being circular on one end, and having some kind of computer key pattern from where you plug it under and into the steering column. I knocked this out on accident and cant find it. The car wont start without it, and am wondering what i might have to do to or how much it would be to get another one of these.
