Bryan, I can almost guarantee you that your transmitters are ok. The problem is most likely in the receiver. For some reason these things go sour after a while. I can't imagine why, but I had a problem where gradually the range has gotten to be unacceptable. I would be ok with 10 feet if it really worked at 10 feet, but in my situation it had to be point blank and into the glass, otherwise no go. I got new transmitter from Volvo (my car is still under warranty) and no real change occurred (before complaining to the dealer I tried changing batteries in the remote with no results). Finally, I talked the dealer into replacing the receiver and bingo! The thing works like a champ from at least 100 feet away and it doesn't matter if you hold the remote to the chin or shove it up your ear (I didn't really try that). Basically on my approach to the car I push the button on the remote in my pocket and the car responds. This is what I am looking for and this is the way it worked when new. IT seems with time these things diminish in performance for some reason and I would like to figure out why. If it is heat as I suspect, then maybe the receiver needs to be relocated elsewhere eve at the expense of some range (I really do not need 100 feet, I actually would prefer a somewhat shorter range to prevent accidental transmission).

This is why I am trying to tap into collective wisdom on this board.

Good luck.
