Signal interference is another frequent cause of Citroen remote controls not working. This can occur when there is an electrical field in the vicinity of the vehicle or other transmitters that operate on the same frequency. The key fob will begin working again after you have left the zone of interference.

This will erase any remaining electricity, allowing the system to reboot.
It is essential to verify the size and type of the battery prior to replacing it. If the battery you replace isn't big enough or has an unsuitable voltage, it can damage the circuit board in the key fob.
