After that dry the circuit board as much as you can with a cotton swab dipped in isopropyl alcohol or an electronic cleaner. If it still doesn't work, it may be time to get a new key for citroen c4 key fob.

Another reason that is commonly cited for Citroen c3 remote control not working is signal interference. This could happen if there is an electrical signal near the car or other transmitters using the same frequency. Once you have left the area of interference the key fob will begin working again.

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 is not correct the receiver won't recognize the car key and display a message telling you "key not detected". This could be a frustrating issue, especially when trying to start your car.

Dead 12 volt battery

It is possible that your key fob is damaged if it stops working after changing batteries.

This will remove any residual electrical energy, allowing the system to reboot.

It is crucial to determine the size and type of the battery prior to replacing it. The circuit board on the fob's key can become damaged in the event that the replacement battery is too big or has an unrelated voltage. You should also clean any corrosive materials off the chip in the fob prior to installing the new battery. The proper type of battery will ensure that the key fob is sealed and protected against moisture. Once the key fob's been reinstalled, it should function normally.
