I got my G6 almost a year ago now, and the remote that controls the lock/unlock and remote starter died not 3 months after buying the thing. At first it started to only work at short range and eventually would only work some days and not others. Shortly after it just completely stopped working. I am thinking the battery in it just died? Does anyone know if it's possible to replace the battery in that thing or am I screwed into having to get a new one from the dealer?
