I went to the dealership here in town and they charged me 69 bux. then 40 bux an hour to program but it only took the guy like 15 minutes so he only charged me a grand total of 82.33 after tax. order one from O'reilly's or something. In the back of your user manual, you can order the GM book with exact details on your GP, better than chiltons or the other books too. Sorry to not mention, but i live in Grand Forks ND, and our dealership is named Rydell's...cheverolet buICK and gmc now.
