Dead coin battery
If your Citroen C3's main fob no longer works, the first thing to look for is if the battery is dead. The batteries in the fobs are small round coins that can be changed in a matter of seconds.

Once the contacts have been cleaned, you can insert the new battery. Just be careful not to mix the two kinds because they differ in their voltages and diameters.
The next step is to check 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 an amount that is above or below its threshold, it has to be replaced. You may also try getting your car started using an additional key, however this might not work in all situations.

Water damage
If the key fob is underwater, it may lose its signal to the car. It is best to remove it as fast as possible from the pool or puddle. Once you have done that, dry out the circuit board as much as you can using the help of a cotton swab, dipped into isopropyl alcohol or an electronic cleaner. If it still doesn't work it could be the time to replace your key fob.
Signal interference is a different reason for Citroen remote controls not working. This may occur when there is an intense electrical field close to the vehicle, or from other transmitters on the same frequency. Once you leave the area of interference the key fob will start working again.
The Citroen C3 key fob may be inoperable due to worn buttons, signal interference issues, receiver module issues or a dead 12-volt battery or a malfunctioning chip. If this happens, you'll need to get it reset by a professional. This can be done either by a trained mechanic or a Citroen dealer. If the issue is serious the vehicle will need to be it replaced.

Receiver module issue
If your key fob ceases working, it could be due to the receiver module having developed an issue. Water damage is among the numerous causes. This could happen if you lose your keys or wash them. You can fix the problem by removing and cleaning the chip with isopropyl alcohol, or electronic cleaner. This will keep the chip from becoming corroded.
You can also try to reset the receiver module by disconnecting it from the car battery and then waiting for 10 seconds. You can then reconnect the battery and repeat the procedure. If this does not fix the problem, you can take it to a retailer to be repaired.
Another reason why your key might not work is due to interference. It could be caused by other transmitters using the same frequency as your key fob or even objects in your vehicle. If you're not able to fix the problem, you can visit a dealer to get your key fob reprogrammed.
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 isn't correct, the receiver module won't recognize the key and display the message "Key not detected. This can be a gruelling issue, especially if you're trying to start your car.
Dead 12 volt battery
It is possible that your key fob is damaged if it ceases to function after changing batteries.

If this is the case you can reset the on-board computers by disconnection of the battery at 12 volts for around 15 minutes. This will take away any remaining electricity, allowing the system to reboot.
Before replacing the battery it is essential to ensure that it's the right size and type. If the battery you replace is too small or has different voltage, it may damage the circuit board within the key fob. You should also clean any corrosive materials from the chip inside the fob before installing a new battery. The correct type of battery can ensure that the key fob is properly sealed and protected from moisture. After the key fob has been installed, it will function normally. It is possible to use the second key even when your car displays a message that reads "key is not recognized." It could be necessary to press the button several times before it responds.
