Before you replace the battery, remove the button pad and rub it using cotton swabs and alcohol. This will help remove corrosion and clean the contacts which are usually colored gold. Once the contacts have been cleaned, you can then install the new battery. Just be careful not to mix the two batteries because they have different diameters and voltages.

The next step is to check the voltage of the battery. A multimeter that is set to the battery's voltage range should give you an accurate reading. If the battery shows an amount that is above or below its threshold, it needs to be replaced. Try starting your car with an additional key, however it may not work in all situations.

Signal interference is another frequent cause of Citroen remote controls not working. This can occur when there is an electrical field near the vehicle or other transmitters using the same frequency. The key fob will begin working again after you have left the area of interference.

Lastly, the Citroen C3 key fob could be inoperable due to worn buttons signals, signal interference, receiver module issues and a dead 12 volt battery, or a defective electronic chip. If this happens, you'll likely need to get it reprogrammed by an expert. This can be accomplished by a qualified mechanic or at an Citroen dealership.

It could be dangerous for passengers and yourself in the event that the issue isn't fixed.

Receiver module issue


If your key fob isn't functioning it could be because the receiver module might have developed a fault. It could be caused by various factors, including water damage. It can happen when you drop your keys or wash them. You can try to resolve the issue by removing and cleaning the chip using isopropyl alcohol or an electronic cleaner. This will prevent corrosion of the chip.

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 process. If this isn't enough to fix the issue, take it to a dealership to be repaired.

Interference can cause your key to stop working. This can be caused either by other transmitters that operate on the same frequency or objects in your vehicle. If you're not able to fix the issue, you can go to 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 right, the receiver will not recognize the car key and display a message that reads "key not recognized". This could be a frustrating problem, especially when 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 the change of batteries. This is most likely to happen in the event that the key fob was dropped or stepped on, however it can also happen after servicing on your car which requires the removal and reinstallation of panels. When these panels are removed, wires are exposed. If your fob is damaged, it might need to be replaced entirely.

A remote that receives interference from other devices and locations is another possibility. This could make RF signals less effective and hinder the car from recognizing the remote. You can reset the onboard computer if this is the situation by disconnecting the 12-volt battery for 15 minutes. This will erase any remaining electrical charge and allow the system to restart from scratch.

Before replacing the battery, it's crucial to ensure that it's the right size and type. The circuit board inside the key fob can be damaged when the replacement battery is too big or has a different voltage. You should also clean any corrosive materials off the chip in the fob before installing a new battery. The correct battery type will ensure that the key fob is sealed and shielded from moisture. Once the key fob is replaced, it should work normally. In most instances, you can use the second key to start your vehicle even when it displays a message saying "key not recognized." It is possible to press the button a few times before it responds.
