How to Replace the Remote Battery of a Citroen

Model: Citroen C4 MK 2 - Years 2010-2018
Part: Key

If you cannot start the vehicle or enter it, it is likely that the issue is a flat remote battery. In such cases, simply replace it with a new one. For example, take the key/remote of a Citroen C4. First, insert a flathead screwdriver into the small slot and lever it to open the shell cover. Next, remove the central body and then extract the battery. At this point, insert a new battery and reassemble everything.
