It's not related to a longroof, but a general GM question. My mom lost the key fob that controls the unlock/lock/trunk function for her 1995 Seville. I'm going to the junkyard tomorrow, and was wondering if any other gm unit might work? I know it would need to be programmed to fit her car, and I think I remember seeing a thread for that here somewhere. Anyway, any info would be appreciated. Her local mechanic told her that through Cadillac that the part and programing would be over $100. I'd like to help her out if I can. Thanks, Mark.
