Water damage

If the key fob is submerged, it could lose its signal. It is recommended to remove it as fast as you can out of the pool or puddle. Once you have done that dry the circuit board as much as you can using a cotton swab dipped in isopropyl ethanol or electronic cleaner. If the circuit board is still not working then it's the right time to purchase a new key fob.

Another reason that is commonly cited that can be the reason behind Citroen remote control c3 not working is signal interference. This can happen when there is an electrical signal near the car or other transmitters that operate on the same frequency.

Interference can cause your key to stop working. This could be caused by other transmitters using the same frequency as your key fob, or by objects within your vehicle. If you're unable to fix the issue, you can visit a dealer and change the key fob's programming.

The key fob contains a short-range radio transmitter/radio-frequency identification (RFID) chip and antenna, which sends a distinct coded signal to the receiver module in your car. If the signal isn't correct the receiver module will not recognize the key and will display a key not detected message. This could be a very frustrating issue, especially if you're trying to start your car.

If this happens it is possible to reset all on-board computers by disconnection of the battery that is 12 volts for around 15 minutes. This will remove any residual electricity, allowing the system to reboot.

Before replacing the battery it's important to make sure it's of the correct type and size. The circuit board in the fob's circuit board could be damaged if the replacement battery is too big or has different voltage.
