2006 Rendezvous 3.6 xl Key fobs only work right by the driver mirror. I have tried changing batteries (several times) bought new fobs and I am pretty convinced it is not the fobs. I have seen where posts said it could be the receiver antenna, RKE, or remote control door lock receiver. I have searched for hours trying to find the location of it, and I cannot find the part either. Please Help

I'd call the dealer to inquire if any service technical bulletins exist regarding this issue for the 06 Rendezvous.
How did you program the fob/* ? A TechII scan tool is normally required and I'm wondering if this is a programming issue.
Dealer should be also able to advise re locations and parts if any are needed.

I programed the key fobs by inserting and removing key two times and putting the key back in, let go of the door lock, and held lock/unlock buttons on the fob. I will check with the dealer, thanks
