Before you replace the battery, take off the button pad and rub it with cotton swabs or alcohol. These will help remove corrosion, and clean the contacts that are typically gold-colored. After the contacts have been cleaned and sanitized, you can then insert the new battery. Be careful not to mix up the two types since they have different voltages, diameters and shapes.
Next, you will need to check the voltage of the battery. A multimeter that is calibrated to the battery's voltage range will provide you with a precise reading. If the battery is at the value that is either above or below its threshold, it has to be replaced. You can also start your vehicle with a spare keys. However, this may not always work.

If the key fob doesn't function, it might be time to buy an entirely new one.

This may occur when there is a strong electrical field in the vicinity of the car or from other transmitters operating on the same frequency. When you leave the area of interference, your key fob will restart working.
Finally, the Citroen C3 key fob could cease to function due to worn buttons or signal interference, receiver module issues and a dead 12 volt battery, or a malfunctioning electronic chip.

If the issue is serious, you'll need to have it replaced. It's a relatively easy and affordable fix. But you must act quickly. If you put off fixing the issue, the more serious it becomes. It could pose a risk to passengers and yourself if the problem is not solved.
Receiver module issue
If your key fob isn't working the receiver module could have developed an issue. It could be caused by many things like water damage. This can happen if you lose your keys, or wash them. You can try to solve the issue by removing and cleaning the chip using isopropyl ethanol or electronic cleaner. This will keep the chip from corroding.
You can reset the receiver module if you disconnect it from the battery and then wait 10 seconds. You can then reconnect the battery and repeat the procedure. If this doesn't resolve the issue, you can visit a dealership to get it replaced.

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 is not correct, the receiver will not recognize the car key and display a message saying “key not recognized”. This could be a major issue especially when you attempt to start your car.

If this happens, you can reset all on-board computers by disconnecting the battery that is 12 volts for around 15 minutes. This will eliminate any remaining power, allowing the system to restart.
Before replacing the battery, it's important to make sure it's of the correct type and size. If the replacement battery is too small or has different voltage, it can damage the circuit board within the key fob. Before you install a battery you should clean the chip inside the fob in order to eliminate any contaminants that could cause corrosion. Using the right type of battery will ensure that it is properly sealed and protected from moisture. Once the key fob has been reinstalled it should function normally.
