Open up the fob, remove the battery and check for any corrosion on the battery terminal; you might also clean the area using an electronic spray cleaner.

Could be time for a new fob. I just had to replace the fob on my 2010 vehicle as it just stopped working. After I got the new ones programmed I took the old fob apart and found the tiny switches inside were just falling apart.

Usually these keyless entry systems work on a rolling code system. The vehicle computer knows what code to expect next when you use the fob next. If the fob gets out of sync with the vehicle computer for some reason it will stop working. These "tricks" that are all over the internet rarely work. They're usually part of another repair and/or the poster doesn't understand how the system works! Your local locksmith, if it's a good one, or your local Ford Dealer is your best bet. Jim
