I have a 2009 GMC Acadia remote control for sale (4 buttons - Lock, open, Remote start and alarm). 35$ OBO. I bought it online for 60$. My loss is Your treasure. It was used for 1 week and we ended up trading the car - so condition is like new with the new battery. It is easy to program it and no have to take it to the dealer. I can provide You the guidelines on the best ways to program it or I can even program it for You- whatever works.

　　Thanks for looking.
