Once the contacts are cleaned, you can add the new battery. Be careful not to mix the two types because they have different voltages and diameters.

Next, you will need to assess the voltage of the battery. You can get a precise reading using a multimeter, which is calibrated to the battery's voltage range.

Once you've done that then use a cotton swab and isopropyl or electronic cleaner to dry the circuit board. If the key fob still isn't working, it could be time to invest in a new one.

Signal interference is a common reason for Citroen remote control not working.

Interference can also cause your key to stop working. It could be caused due to other transmitters that operate on the same frequency as your key fob, or by objects within your vehicle. If you're unable to fix the issue, visit a dealer and have your key fob reset.

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.

This will eliminate any remaining power and allow the system to start again.

Before replacing the battery, it is important to ensure it is the correct type and size. The circuit board on the key fob can be damaged when the battery you replace is too big or has different voltage. Before installing a battery you should clean the chip of the fob to get rid of any harmful substances. Using the right battery will ensure that it is properly sealed and protected from moisture. Once the key fob has been reinstalled it should function normally. You can usually use the second key if your car displays a message that reads "key not found."
