After that then use a cotton swab, isopropyl or electronic cleaner to dry the circuit board. If it's still not working then it's time for a new key fob.

Signal interference is a different cause of Citroen remote controls not working. This can occur when there is an intense electrical field that is close to the vehicle, or from other transmitters operating on the same frequency. The key fob should start to work again once you are out of the area of interference.

Lastly, the Citroen C3 key fob could be inoperable due to worn buttons, signal interference, receiver module issues, a dead 12 volt battery, or an indefective electronic chip.

Receiver module issue

If your key fob is not functioning it could be because the receiver module might have developed an issue. Water damage is one of the numerous reasons. This can happen when you accidentally drop your keys or wash them. It is possible to solve the issue by removing and cleaning the chip using isopropyl ethanol or electronic cleaner. This will avoid the chip from becoming damaged.

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 doesn't match the receiver module won't recognize the key and will display the message "Key not detected. This can be a frustrating issue, particularly when trying to start your vehicle.

Dead 12 volt battery

You can reset your on-board computer if this is the scenario by disconnecting your 12-volt battery for 15 minutes. This will erase any remaining electricity and allow the system to start from scratch.

It is essential to verify the size and quality of the battery prior to replacing it. The circuit board in the fob's key could be damaged in the event that the replacement battery is too large or has an unrelated voltage. You should also clean any corrosive material from the chip inside the fob prior to installing the new battery. The correct battery type will ensure that the key fob is properly sealed and protected from moisture. After the key fob has been installed, it should work normally.
