I just purchased a 1999 Tahoe and posted some problems I was having with the front doors remote locks not working. I figured "what the hell" if the key works thats fine. I tried all the locks and the key does not work! I am assuming that the doors have been replaced as well as the hatch. What I would like to know is it possible to have keys made that fit or do I need to replace the whole door lock shootin match?By the way, the remote does slightly move the front latches and it unlocks the rear doors and the hatch??
