I am new to this Forum but a long time member of the Corvette Forum. I try & help with Tech. questions when I can so I thought that I would give this Forum a try.
I have a 2002 Envoy that my Wife drives, one of the Key Fobs stopped working so I changed the battery & it still didn't work. I was told the the Dealer had to re-program it so I changed the other battery out & took them both to our local dealer along with the Envoy of cource. They programed them & they worked fine for about three days & first one stopped working then the next day the other stopped working. I have had this done three times by the dealer & it keeps on happening, the last time they kept the Envoy for the whole day & they worked fine. Well it happened again & the Dealership doesn't really know what is causing it or how to fix it, HELP!!!
Thanks
