Hi, does the red LED on the fob light up when a button is pressed?
The solder keeping all the wee bits n' pieces connected in the fob can deteriorate and stop working.
Also try folding up a wee piece of paper and placing it on top of the battery to Push Down on the battery as the cover is installed, this helped mine and works OK now.
