Once you do, dry out the circuit board as much as you can with a cotton swab dipped in isopropyl ethanol or electronic cleaner. If it doesn't work then it's the time to replace your key fob.

Signal interference is a different reason for Citroen remote controls not working. This can occur when there is an electrical signal near the car or other transmitters on the same frequency. Once you leave the area of interference the key fob will begin working again.

The Citroen C3 key fob might be inoperable due to worn buttons problems with signal interference, receiver module problems, a dead 12-volt battery or a damaged chip. If this happens, you'll probably require it to be reset by a professional. This can be accomplished by a qualified mechanic or at a Citroen dealership.

It is crucial to determine the size and type of the battery before replacing it. The circuit board inside the fob's key could be damaged if the replacement battery is too big or has an incompatible voltage. Before installing a new battery, you must clean the chip inside the fob to remove any corrosive substances.
