The battery was low in one of 2 fobs. I replaced the battery and the fob now starts car and i can manually lock and open doors, trunk and charge door. However none of the buttons on the fob work. Our dealership wasn't much help. Has anyone had this happen? Did you resolve it? I did take it apart and put it together gain 2x so if it was just a mechanical issue that I did not press the 2 parts of the fob together tight enough I think that would have solved it but still no working buttons, including alarm button.
