Once the contacts have been cleaned and sanitized, you can then insert the new battery. Be careful not to mix the two types as they have different voltages and sizes.

Next, you will need to check the voltage of the battery. You can get an accurate reading using a multimeter, which is set to the battery voltage range. If the battery shows a value above or below its threshold, it is required to be replaced. You can also try to start your car using a spare key, however it may not work in all situations.

A CITROEN dealer can find the code for your vehicle's immobiliser and order a new battery.

Water damage

If the key fob is under water, it could lose its signal to the car. It is advised to get it out as soon as possible from the pool or puddle. After this make use of the cotton swab along with isopropyl or electronic cleaner to clean the circuit board. If it's still not working then it's time for a new key fob.


Another common cause the most common reason for Citroen c3 remote control not working is signal interference. This could happen when there is a strong electrical field near the vehicle, or from other transmitters operating on the same frequency. Once you leave the interference area your key fob will begin working again.

Additionally, the Citroen c3 key fob can stop working due to worn buttons signals, signal interference, receiver module issues or a dead 12 volt battery, or a defective electronic chip. You'll have to get it reset in the event of this. This can be accomplished by a qualified mechanic or at an Citroen dealership. If the issue is significant, you'll need to have it replaced.

Receiver Module Issue

If your key fob stops working, it could be due to the receiver module having developed an issue. Water damage is one of the numerous causes. This can happen if drop your keys or wash them. You can try to fix it by removing the chip and cleaning it with isopropyl or an electronic cleaner. This will help to avoid the chip from becoming damaged.

You can also reset the receiver module by disconnecting it from the car battery and letting it sit for 10 seconds. Then reconnect the battery to the vehicle and repeat the process. If this doesn't fix the issue, you can go to a dealership and have it replaced.

Another reason why your key might not work is due to interference. It could be caused by other transmitters on the same frequency, or by objects in your vehicle. If you are unable to solve the issue, take your key fob in to a dealer and have it 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 doesn't match the receiver module won't recognize the key and display an error message that states the key is not detected. This could be a very frustrating issue, especially if you're trying to start your vehicle.

Another possibility is that the remote is receiving interference from other devices or places. This can cause RF signals to become weak and prevent the car from understanding the remote. You can reset the onboard computer if this is the situation, by disconnecting the 12-volt battery for 15 minutes. This will eliminate any remaining electricity, allowing the system to reboot.

It is essential to confirm the size and quality of the battery before replacing it. If the replacement battery is too small or has an incompatible voltage, it could damage the circuit board in the key fob. You should also clean any corrosive materials off the chip in the fob before installing the new battery. Making sure you choose the right battery can help ensure that it is sealed and shielded from moisture. Once the key fob is put back in place, it should function normally.
