Signal interference is a common reason for Citroen remote controls not working. This can occur when there is an intense electrical field in the vicinity of the Car Key Locksmith, or from other transmitters operating on the same frequency. Once you have left the area of interference your key fob will begin working again.

The Citroen C3 key fob could cease to function due to worn buttons or signal interference issues, receiver module issues or a dead 12-volt battery or a malfunctioning chip.

Receiver module issue

If your key fob stops working, it might be because the receiver module has developed an issue. Water damage is one of the numerous reasons. This can happen if you drop your keys, or wash them. You can fix the problem by removing and cleaning the chip using isopropyl alcohol, or car key locksmith electronic cleaner. This will avoid the chip from becoming damaged.

You can reset the receiver module when you disconnect it from the battery and wait 10 seconds. Then, reconnect the battery and repeat the procedure. If this fails to fix the issue, visit a dealership to get it replaced.

Another reason why your key might be unable to function is due interference. It could be caused due to other transmitters using the same frequency as your key fob or by objects within your vehicle. If you're not able to fix the issue, you can bring your key fob to a dealer to be changed to a different frequency.

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 will display a key not detected message. This could be a major issue particularly 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. This is especially true in the event that the key fob was dropped or stepped on, but it can also happen following maintenance on your vehicle which requires the removal and reinstallation of panels.

A fob that is receiving interference from other devices and locations is also a possibility. This can cause RF signals to become less effective and hinder the car's recognition of the remote. If this is the case it is possible to reset all on-board computers by disconnecting the battery with 12 volts for around 15 minutes. This will eliminate any remaining power, allowing the system to reboot.

Before replacing the battery, it is essential to ensure it's the correct type and size. If the replacement battery isn't big enough or has a different voltage, it may damage the circuit board in the fob's key. Also, you should clean any corrosive substances from the chip in the fob before installing the new battery. The correct battery type will ensure that the key fob is sealed and shielded from moisture. Once the key fob has been reinstalled, it should function normally. It is possible to use the second key if your car displays a message that reads "key not found." It is possible to press the button multiple times before it responds.
