If the key fob still isn't working, it may be time to buy a new one.

Another reason that can be cited one of the main reasons for Citroen c3 remote control not working is signal interference. It can happen when there is a strong electrical field in the vicinity of the vehicle or from other transmitters on the same frequency.

If this happens you can reset the on-board computers by disconnecting the battery that is 12 volts for about 15 minutes. This will remove any residual electric current, allowing your system to reboot.

It is important to check the size and type of the battery prior to replacing it. If the replacement battery is too small or has a different voltage, it could damage the circuit board within the fob's key. Before installing a battery you should clean the chip of the fob to get rid of any corrosive substances.
