2000 jimmy. a few months back my original keyfob I got with my truck took a dirt nap. so I bought 2 NEW ones off ebay. I programed them using the key on, off, on, off, ect. and they both worked perfect. then a few days ago (after the 30 day return of course) the one I was using stopped working. I changed the battery and it didn't help. reprogrammed them and it helped for one click. I found out they both do work BUT ONLY from the INSIDE of the truck. once I close the door it BARELY works if im lucky. an given the fact that they both only work from the inside leads me to belive it maybe an issue with my truck, but I don't know where to start. anyone know what maybe going on here?
