After that using the cotton swab along with isopropyl or electronic cleaner to dry the circuit board. If it doesn't work then it's time to get a new key fob.

Signal interference is another common cause of Citroen remote controls not working. This can happen when there is an electrical signal near the car or other transmitters on the same frequency. Once you have left the area of interference, your key fob will be working normally again.

The Citroen c3 key fob can stop working due to worn buttons or signal interference, receiver module issues and a dead 12 volt battery, or a damaged electronic chip. If this happens, you'll likely require it to be changed by a certified expert. This can be done by a qualified mechanic or a Citroen dealer. If the issue is significant you may have to replace it.

Receiver Module Issue

If your key fob ceases functioning, it could be due to the receiver module having developed an issue. It could be caused by many things such as water damage. This can happen if you drop your keys, or wash them. You can attempt to solve the issue by removing and cleaning the chip with isopropyl alcohol, or electronic cleaner. This will stop the chip from corroding.

You can also reset the receiver module when you disconnect it from the battery and then wait 10 seconds. Then, reconnect the battery to the vehicle and repeat the process. If this doesn't fix the issue, you can visit a dealership to have it replaced.

This will clear any residual electrical charge and allow the system to restart again.

Before replacing the battery, it's important to make sure that it's the right size and type. If the replacement battery is too small or has a different voltage, it can damage the circuit board in the fob's key. Before installing a battery, you should clean the chip inside the fob to get rid of any contaminants that could cause corrosion.
