Hi all. Just bought a 2008 G6 GT. Previous owner said that both fobs worked but now they don't. NO functions on the fobs work. She said it started around the time that she got her car battery replaced. Both fob batteries are new. They look like they are in good shape too. I checked the fuse associated with the receiver and it was ok. It's not often that BOTH fobs don't work like this so I'm getting the impression that the issue might be something within the vehicle itself. Any ideas what it might be???
