How to Replace the Key Battery of the Ford C Max

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

To open the casing of your key, you will need a flathead screwdriver to lever in the gap between the two sides. This will separate the two halves of the key, giving you access to the side where the battery is located and the other side where the control circuit is. You can now replace the battery or make any necessary changes. To close the casing, simply align the two parts and press them together until they click into place. Now, test the key with the new battery.
