If it's still not working It could be time to get a new key fob.

Signal interference is another frequent reason for citroen c2 key programming remote controls not working. This could happen if there is an electrical field in the vicinity of the car or other transmitters operating on the same frequency.

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

It is essential to verify the size and quality of the battery prior to replacing it.
