My 2012 key FOB stopped working.
We tried replacing the battery.
Nothing works not the door unlock or remote start.

 

I have problems out of mine from time to time. Right now, all it takes is to brush you finger along the surface of the thing and it'll lock or unlock depending on where it's touched. I think it's likely full of pocket lint - think I'm gonna open it up and use some compressed air to try and clean it out.
