My factorykeyless entry stop working I thoughtit was the battery in the remote but replaced it and still nothing. I even reprogrammed it and the remote responds but afterwards still nothing.

 

remote responds???? how do you know if it is not working....I had one awhile back just worked intermittent, figured I dropped it and broke a connecton on the little computer board inside, it worked if I tapped it, Try a new one, see if it works, if not something in the truck is not talking to the remote

 

Those remotes do break the boards on the inside all the time. I would suspect that before anything else. JHH
