The next step is to check the voltage of the battery. You can get a reliable reading using a multimeter, which is calibrated to the battery's voltage range. If the battery's current value is higher or lower than the threshold, it needs to be replaced. You could also start your car with a spare key. However, this might not always work.

Water damage
If the key fob is submerged, it may lose its signal. If this happens, it's a good idea to pull it out of the puddle, pool, or washing machine as quickly as you can. After this, use the cotton swab along with isopropyl or electronic cleaner to clean the circuit board. If it 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. It can happen when there is an electrical signal near the vehicle or other transmitters using the same frequency. Once you leave the area of interference, your key fob will be working normally again.

Receiver Module Issue
If your key fob isn't working the receiver module could have developed an issue. This could be due to various factors that include water damage. This can happen if you lose your keys, or wash them. You can fix it by removing the chip and cleaning it with isopropyl or electronic cleaner. This will keep the chip from becoming corroded.
You can reset the receiver module if you disconnect it from the battery and wait 10 seconds. You can then reconnect the battery and repeat the process. If this does not resolve the issue, bring it to a dealer for replacement.
Interference can also cause your key to stop working. This can be caused by other transmitters that utilize the same frequency as your key fob, or by objects inside your vehicle. If you are unable fix the issue, you can bring your key fob to a dealer to be 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. If the signal doesn't match the receiver module will not recognize the key and display an error message that states the key is not detected. This can be a frustrating problem, especially when you're trying to start your car.
Dead 12 volt battery
It is possible that the key fob you have purchased has been damaged if it ceases to function after changing batteries. This is more likely if your key fob has been dropped or stepped over, but can also be the result of a service that requires the removal of the panels and reinstallation. When these panels are removed, the wires are exposed. If your fob is damaged, you might require replacement completely.
Another possibility is that the remote receives interference from other devices or places. This could cause RF signals to become weak and prevent the car from being able to recognize the remote. If this is the case it is possible to reset all on-board computers by disconnection of the battery that is 12 volts for approximately 15 minutes. This will take away any remaining electric current, allowing your system to reboot.
It is essential to verify the size and type of the battery prior to replacing it. If the replacement battery is too small or has an unsuitable voltage, it may damage the circuit board inside the fob's key. Before installing a new battery, you should clean the chip of the fob to eliminate any harmful substances. Using the correct type of battery will ensure that it is properly sealed and shielded from moisture. After the key fob has been reinstalled, it should function normally. You should be able to use the second key even when your car displays a message stating "key not found." You may need to press the button a few times before it responds.
