Dead coin battery
If your Citroen C3's main fob is not working the first thing you should check is if the battery is dead. Fobs are small, coin-shaped batteries that can be replaced within a few minutes. You can find these at general stores, home improvement stores, and even auto parts stores. Make sure you purchase the correct battery, however. Batteries for fobs are usually CR2025 or CR2032, however you should check the owner's manual of your vehicle to determine what kind is required.

The next step is to determine the voltage of the battery. A multimeter that is set to the battery's voltage range should provide a precise reading. If the battery's current value is above or below threshold, then it needs to be replaced. You could also start your car with a spare key. However, this may not always work. If the problem persists you should visit a CITROEN dealer with your V5 registration document and personal identifi cation documents. A CITROEN dealer can locate the code for your vehicle's immobiliser system, and request an alternative battery.
Water damage
If the key fob is submerged, it can lose its signal. It is best to remove it as soon as you can out of the pool or puddle. Once you have done that, dry out the circuit board as best you can with the help of a cotton swab, dipped into isopropyl ethanol or electronic cleaner. If the key fob still isn't working, it may be time to buy a new one.
Signal interference is another common cause of Citroen remote controls not working. It can happen when there is an intense electrical field close to the car or from other transmitters on the same frequency. The key fob is expected to begin to work again once you are out of the area of interference.
Finally, the Citroen C3 key fob might not function due to worn buttons signals, signal interference, receiver module issues or a dead 12 volt battery, or a malfunctioning electronic chip. You'll need to have it replaced if this happens. This can be accomplished by a qualified mechanic or at a Citroen dealership. If the issue is significant, you may need to replace it. It's an easy and affordable fix. However, you need to get it done quickly. The longer you put off taking action to resolve the issue, the more deteriorated it becomes. It could pose a risk to passengers and you when the issue is not resolved.
Receiver module issue
If your key fob stops functioning, it could be due to the receiver module having developed a fault. Water damage is one of the numerous reasons. This can happen when you drop your keys, or wash them. You can try to fix the problem by removing and cleaning the chip using isopropyl ethanol or electronic cleaner. This will stop the chip from corroding.
You can also reset the receiver module by disconnecting it from the car battery and waiting for 10 seconds. You can then reconnect the battery and repeat the process. If this fails to fix the issue, you can visit a dealership to have it replaced.
Another reason your key may stop working is due interference. It could be caused due to other transmitters using the same frequency as your key fob or even objects in your vehicle. If you are unable to resolve the issue, go to a dealership to have 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 will not recognize the car key and display a message stating "key not recognized". This can be a frustrating issue, especially if you're trying to start your vehicle.
Dead 12 volt battery
If your key fob ceases working after a battery change, it may be damaged. This is particularly true when the key fob has been dropped or stepped on. However, it could also occur following servicing on your car which requires the removal and reinstallation of panels. When these panels are removed, the wires are exposed. If your fob is damaged, you might require a complete replacement.
A fob that is receiving interference from other devices and locations is also a possibility. This could cause RF signals to weaken and block the car from understanding the remote. If this is the case, you can reset all on-board computers by disconnecting the battery at 12 volts for around 15 minutes. This will take away any remaining electric current, allowing your system to reboot.
It is essential to confirm the size and type of the battery before replacing it. If the battery you replace isn't big enough or has an unsuitable voltage, it can damage the circuit board in the fob's key. You should also clean any corrosive materials off the chip in the fob before installing a new battery. The right battery type can ensure that the key fob is properly sealed and protected against moisture. Once the key fob is reinstalled, it should work normal. You should be able to use the second key if your car displays a message that reads "key is not recognized." It is possible to press the button a few times before it responds.
