If it doesn't work it could be time for a new key fob.

Signal interference is another frequent reason for Citroen remote control not working. It can happen when there is an intense electrical field in the vicinity of the vehicle, or from other transmitters operating on the same frequency. The key fob should begin working again after you leave the zone of interference.

This will erase any remaining electricity, allowing the system to restart.

Before replacing the battery, it is important to ensure it's the correct size and type. If the battery you replace is too small or has a different voltage, it may damage the circuit board inside the fob's key.
