Part: Key

The selected video shows how to change the battery in the remote control of a Citroen C4. To replace the battery, take the remote and open the casing using the internal mechanical key or a small screwdriver in the side slot. Gently pry until the two halves separate. At this point, you will have access to the battery compartment, where you will find a button cell battery, usually a CR2032. Remove it, taking care to note the position of the '+' side.
