Replacing the key remote battery on Citroen C4

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

In this description, we will see how to dismantle and replace the battery of the remote key for a second generation Citroen C4, in simple steps. Take the remote in hand and use a sharp object to pry open the slots on the sides, as shown in the video; this will open the remote into two parts and give access to the remote battery. Then, remove it by prying and replace it with a new one of the correct type (in this case, a CR 2032 3V). Finally, insert it the right way round and reassemble everything!
