Wondering if that is the route I am also going to have to go? I have 900 miles on my 09 Srt8, going on 4 months in my possesion and when it's hot the key fob will not ever work, but starts right up when its cool. Figured it was the heat long before seeing this thread, just because it was so obvious. I am going to take it in tomorrow to see what they say and go from there...
