Just got my GXP on friday. My key fob is acting up. The panic and trunk realease work perfect. But the lock and unlock act up a lot. I have to press down really hard and hold for a few seconds and itll work. But sometimes I have to press and hold a few times until it reacts. So i know the battery its not the problem. Could a new shell solve my problem? I found some on ebay that come with the shell and the buttons.
