Replacing the key battery on a Ford C-Max

Model: Ford C Max MK 2 - Years 2010-2019
Part: Key

Using the small button on the remote, remove the cover with the Ford emblem from the remote, as shown in the video. Once done, you can also extract the manual spare key located inside (to use if you need to start the car and the battery is flat). At this point, use a small flat screwdriver to pry open the seams of the remote and separate it into two halves. Here is the battery! Now, simply pry underneath it to remove it and then replace it. Reassemble everything.
