Another common reason that can be the reason behind Citroen remote control c3 not working is signal interference. It can happen when there is a strong electrical field that is close to the vehicle or from other transmitters operating on the same frequency. The key fob should start to work again once you have left the area of interference.

Issue with the Receiver module

If your key fob stops working, it might be due to the receiver module having developed a fault. It could be caused by many things like water damage. This could happen if you drop your keys, or wash them. It is possible to fix the problem by taking off the chip and cleaning it with isopropyl or electronic cleaner. This will keep the chip from getting corroded.

You can also reset the receiver module by disconnecting it from the car battery and letting it sit for 10 minutes. Then, reconnect the battery and repeat the process. If this does not resolve the problem, you can take it to a retailer to be repaired.

Another reason why your key could stop working is due interference. This can be caused by other transmitters that operate on the same frequency as your key fob, or by objects in your vehicle. If you're not able to fix the problem, you can visit a dealer and have your key fob 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 isn't right the receiver module will not recognize the key and display the message "Key not detected. This can be a gruelling issue, especially when trying to start your car.

Dead 12 volt battery

It is possible that the key fob you have purchased has been damaged if it stops working after a change of batteries.

You can reset the onboard computer if this is the situation. You can do this by disconnecting the 12-volt battery for 15 minutes. This will take away any remaining power, allowing the system to reboot.

It is essential to verify the size and type of the battery prior to replacing it. If the replacement battery isn't big enough or has an incompatible voltage, it can damage the circuit board within the fob's key. You should also remove any corrosive substances from the chip in the fob prior to installing the new battery. The right battery type can ensure that the key fob is properly sealed and shielded from moisture. Once the key fob's been reinstalled, it will function normally.
