Once you have done that dry the circuit board as much as you can using a cotton swab that has been dipped in isopropyl alcohol, or electronic cleaner. If the key fob isn't working, it may be time to invest in a new one.

Another common cause the most common reason for Citroen c3 remote control not working is signal interference. This can occur when there is an electrical field near the vehicle or other transmitters that operate on the same frequency. Once you leave the area of interference, your key fob will begin working again.

Receiver module issue

If your key fob ceases functioning, it could be due to the receiver module having developed a fault. This could be due to various factors like water damage. This can happen if lose your keys, or wash them. You can fix the problem by removing and cleaning the chip using isopropyl alcohol or an electronic cleaner. This will prevent the chip from getting corroded.

You could also try to reset the receiver module by disconnecting it from the car battery and letting it sit for 10 seconds. Then, reconnect the battery and repeat the process. If this fails to fix the issue, go to a dealership and have it replaced.

Another reason why your key could stop working is due interference. This could be caused by other transmitters that utilize the same frequency as your key fob, or by objects within your vehicle. If you are unable to fix the issue, take your key fob to a dealer and have it reset.

This will remove any remaining power and allow the system to begin from scratch.

Before replacing the battery it is essential to ensure it's of the correct size and type. If the battery you replace is too small or has an unsuitable voltage, it can damage the circuit board within the key fob.
