You know how hard it is to search for Key FOB? Two three letter words, impossible! Lol....
Anyway, I've been have range issues with my remote for a few months now. Actually since December. I've mentioned it to the dealer every time the truck was in for work. But every time out would work at a relatively good distance in the dealer parking lot. Mine was bad, you had to be within 10 feet of the truck. This was with new batteries in both key remotes.
Finally, the dealer did some digging and tested it away from their lot and saw the problem.
They found a TSB and a replacement part inside the remote to replace. The range is improved to a reasonable distance.
When the dealer called and said what he changed, I couldn't believe that a small gasket would make a difference. It wasn't until I changed out the second remote that I could see what was different.
The new gasket gas two small nipples on it like. These must hold the battery into a better position with the contacts. That's all I could think of.
The part number is above. I can't imagine that it would cost much.
Chime in if you change out this part and it helps the distance you key remote out key fob works.
