Signal interference is another common cause of Citroen remote controls not working. It can happen when there is an intense electrical field near 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.

Finally, the citroen relay key fob programming C3 key fob may stop working due to worn buttons and receivers, signal interference, module issues or a dead 12 volt battery, or a defective electronic chip.

Issue with the Receiver module

If your key fob ceases working, it could be due to the receiver module having developed an issue. This can be caused by a number of things like water damage. This could happen if you drop your keys, or wash them. You can solve the problem by removing your chip and cleaning it with isopropyl or electronic cleaner. This will keep the chip from corroding.

You can also reset the receiver module by disconnecting it from the car battery and then waiting for 10 minutes. You can then reconnect the battery and repeat the process. If this isn't enough to fix the problem, you can take it to a dealer to have it replaced.

Another reason why your key might stop working is due to interference. It could be caused by other transmitters using the same frequency or objects in your vehicle. If you're unable fix the issue, you can 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 module will not recognize the key and display a key not detected message. This is a problem that can be frustrating especially when you attempt to start your vehicle.

Dead 12 volt battery

If your key fob ceases working after changing the battery the device could be damaged. This is particularly true if the key fob was dropped or stepped on, but it can also happen after service on your car that requires removal and reinstallation of the panels. Wires are exposed when the panels are removed. If your fob was damaged, it may require replacement completely.

Another possibility is that the fob is getting interference from other devices or locations. This could cause RF signals to weaken, preventing the car from being able to recognize the remote. If this is the case you can reset the on-board computers by disconnecting the 12 volt battery for around 15 minutes. This will take away any remaining power, allowing the system to reboot.

Before replacing the battery, it is important to ensure it's of the correct size and type. If the battery you replace isn't big enough or has different voltage, it can damage the circuit board in the fob's key. It is also recommended to clean any corrosive materials from the chip in the fob prior to 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 replaced, it should work normally.
