Next, you will need to assess the voltage of the battery. You can get a precise reading with a multimeter that is set to the battery’s voltage range. If the battery’s value how much is a replacement citroen key higher or lower than the threshold, then it must be replaced. You can also start your car by using a spare key.

After that, use a cotton swab and isopropyl or electronic cleaner to dry the circuit board. If it doesn’t work It could be time to get a new key fob.

Signal interference is another frequent cause of Citroen remote control not working. This can occur when there is a strong electrical field that is close to the car, or from other transmitters on the same frequency. The key fob is expected to begin working again after you leave the zone of interference.

The Citroen C3 key fob could be inoperable due to worn buttons or signal interference, receiver module issues, a dead 12 volt battery, or an indefective electronic chip.

Issue with the Receiver module

If your key fob stops working, it might be because the receiver module has developed a fault. Water damage is one of the many causes. This can occur when you drop your keys, or wash them. You can try to resolve the issue by removing and cleaning the chip with isopropyl alcohol, or electronic cleaner. This will prevent corrosion of the chip.

You can also reset the receiver module when you disconnect it from the battery for 10 seconds. Then, reconnect the battery and repeat the process. If this isn’t enough to fix the issue, take it to a retailer to be repaired.

Another reason why your key could be unable to function is due interference. It could be caused due to other transmitters that use the same frequency as your key fob, or by objects inside your vehicle.

This will remove any remaining electricity and allow the system to begin again.

Before replacing the battery it’s important to make sure it is the correct size and type. If the replacement battery isn’t big enough or has a different voltage, it could damage the circuit board inside the key fob. You should also remove any corrosive material from the chip in the fob prior to installing the new battery.
