Citroen C3 Key Fob Troubleshooting

The key fob of the Citroen C3 can not function for a variety of reasons. This includes worn buttons, poor contact between the battery and the water and receiver module problems. Examine the 12 volt batteries.

If the key fob will not unlock your car, you could be experiencing deprogramming. This happens when certain button sequences send an instruction to the onboard computer to remove the key from its list of access.

Dead coin battery

If the key fob on your Citroen C3 is no longer working, first make sure the battery has died. Fobs are small, coin-shaped batteries that can be replaced within a few minutes. These can be found in general stores, home improvement stores and auto parts stores. Make sure you buy the correct one, however. The batteries for fobs are usually CR2025 or CR2032, however you should check the owner's manual for your vehicle to determine which kind of battery is needed.

Take off the button pad and then use cotton swabs or alcohol to clean it. They will remove the corrosion, and clean the contacts which are typically gold-colored. Once the contacts are cleaned then you can put in the new battery. Just be careful not to mix the two types as they have different voltages and diameters.

The next step is to determine 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 is at an amount that is above or below its threshold, it has to be replaced. You can also start your vehicle with a spare key. However, this might not always work. If the issue persists, visit an CITROEN dealer with your V5 registration document and personal identifi cation documents. A CITROEN Dealer can locate the code of your vehicle's immobiliser and can order a new battery.

Water damage

If the key fob is submerged, it may lose its signal. If replacement citroen key fob happens, it's a good idea to remove it of the puddle, pool or washing machine as soon as you can. After this, use an swab of cotton and isopropyl or electronic cleaner to clean the circuit board. If the key fob still doesn't function, it might be time to invest in a new one.


Signal interference is another common cause of Citroen remote control not working. It can happen when there is an intense electrical field that is close to the vehicle or from other transmitters operating on the same frequency. The key fob is expected to begin to work again once you have left the zone of interference.

Lastly, the Citroen C3 key fob may be inoperable due to worn buttons, signal interference, receiver module issues or a dead 12 Volt battery, or a damaged electronic chip. It will need to be reprogrammed when this happens. This can be done by a trained mechanic or at a Citroen dealership. If the problem is severe it's time to have it replaced. It's a relatively easy and inexpensive fix. But you have to act quickly. The longer you put off fixing the issue, the more difficult it becomes. It could be dangerous for passengers and yourself If the issue isn't resolved.

Receiver Module Issue

If your key fob ceases functioning, it could be due to the receiver module having developed a fault. Water damage is among the numerous reasons. This can happen when you drop your keys or wash them. It is possible to repair the issue by removing the chip and cleaning it with isopropyl and electronic cleaner. This will stop the chip from corroding.

You can also reset the receiver module when you disconnect it from the battery and wait 10 seconds. Then reconnect the battery to the car and repeat the process. If this does not fix the issue, take it to a dealership to be replaced.

Another reason why your key might stop working is due to interference. This can be caused either by other transmitters that operate on the same frequency, or by objects inside your vehicle. If you are unable fix the issue, bring your key fob to a dealer and have it 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 right it will not recognize the car key and display a message telling you "key not detected". This could be a major issue, especially when trying to start your vehicle.

Dead 12 volt battery

If your key fob ceases working after the battery has been changed, it may be damaged. This is most likely to happen in the event that your key fob has been dropped or stepped over However, it can happen after a service that requires the removal of panels and then reinstallation. When these panels are removed, the wires are exposed. If your fob is damaged, you might require replacement completely.

A fob that is receiving interference from other devices or locations is a second possibility. This can cause RF signals to weaken and stop the car from acknowledging the remote. If this is the case you can reset all computer systems on board by disconnecting the battery with 12 volts for approximately 15 minutes. This will take away any remaining electrical energy, allowing the system to reboot.

Before replacing the battery it's crucial to ensure it's the correct size and type. If the battery you replace is too small or has a different voltage, it could harm the circuit board in the key fob. Before installing a new battery, you must clean the chip of the fob to eliminate any harmful substances. The correct battery type will ensure that the key fob is sealed and protected from moisture. Once the key fob is installed, it will function normally. It is possible to use the second key even the car displays a message stating "key not detected." You may need to press the button several times before it responds.
