Once the contacts are cleaned, you can put in the new battery. Be careful not to mix up the two types since they have different voltages, diameters and shapes.

The next step is to determine the voltage of the battery. A multimeter that is calibrated to the battery's voltage range will give you an accurate reading. If the battery is at a voltage that is higher or lower than its threshold, it will need to be replaced.

Once you've done that then use an swab of cotton and isopropyl or electronic cleaner to dry the circuit board. If the key fob doesn't function, it might be time to get an entirely new one.

Signal interference is another common reason for Citroen remote control not working. It can happen when there is a strong electrical field close to the vehicle, or from other transmitters operating on the same frequency. The key fob will begin to function again after you have left the area of interference.

This will clear any residual electricity 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. The circuit board in the fob's circuit board could be damaged when the replacement battery is too large or has an unrelated voltage. It is also recommended to clean any corrosive substances from the chip inside the fob before installing the new battery.
