In this video, learn how to disassemble and replace the battery of the key fob on a Ford Focus MK3 by following these simple steps. First, take your key fob and get something thin to pry open the sides, separating the fob into two parts; this will give you access to the electronic board and the battery itself.

Now, remove the battery and replace it with a new one of the correct type (in this case, a CR 2032 3V); insert it the right way round and reassemble everything by reversing the procedure!
