Water damage
If the key fob is submerged it may lose its signal. If this happens, it's a good idea to fish it out from the pool, puddle or washing machine as quickly as you can. After that, dry out the circuit board in the best way you can using an abrasive swab of cotton that's been soaked in isopropyl alcohol or electronic cleaner. If the key fob still does not work, it may be time to buy another one.
Another common reason for Citroen remote control c3 not working is signal interference. This could happen if there is an electrical field in the vicinity of the vehicle or other transmitters on the same frequency. Once you leave the interference area, your key fob will start working again.
