Once the contacts are cleaned, you can then put in the new battery. Be careful not to mix the two types as they have different voltages, diameters and shapes.

The next step is to test the voltage of the battery. A multimeter that is calibrated to the battery's voltage range should give you a reliable reading. If the battery's voltage is higher or lower than the threshold, it needs to be replaced. You may also be able to start your car with a spare keys. However, this may not always work. If the issue continues go to an CITROEN dealer with your V5 registration document and personal identification documents.

Water damage

When the key fob goes submerged, it could lose its signal to the car. If this occurs, it's a good idea to fish it out of the pool, puddle, or washing machine as fast as you can. After that make use of a cotton swab and isopropyl or electronic cleaner to clean the circuit board. If the key fob still isn't working, it may be time to invest in a new one.

Signal interference is another common cause of Citroen remote control not working. This can occur when there is an electrical field in the vicinity of the vehicle or other transmitters using the same frequency. The key fob should start to function again after you leave the zone of interference.

The Citroen C3 key fob could stop working because of worn buttons signals, signal interference issues receiver module problems, a dead 12-volt battery or a defective chip. If this happens, you'll need to get it reprogrammed by an expert. This can be done by a trained mechanic or at a Citroen dealership. If the issue is serious then you'll have to get it replaced.

If your key fob isn't functioning the receiver module could have developed a fault. Water damage is among the many reasons. This could happen if you drop your keys or wash them. You can resolve the issue by removing and cleaning the chip with isopropyl alcohol or an electronic cleaner. This will keep the chip from corrosion.

You can also try to reset the receiver module by disconnecting it from the car battery and letting it sit for 10 seconds. Then reconnect the battery to the car and repeat the procedure. If this isn't enough to fix the issue, you can bring it to a dealer to have it replaced.

Another reason your key could stop working is due interference. This can be caused by other transmitters that use the same frequency as your key fob or by objects in your vehicle. If you are unable to fix 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 isn't correct the receiver module won't recognize the key and will display the message "Key not detected. This is a problem that can be frustrating especially when trying to start your vehicle.

Dead 12 volt battery


If your key fob ceases working after a battery change It could be damaged. This is most likely to happen in the event that the key fob was dropped or stepped on.

If your fob is damaged, you may have to replace it completely.

Another possibility is that the fob receives interference from other devices or locations. This can make the RF signals weaker and block the car's recognition of the remote. You can reset your on-board computer if this is the situation. You can do this by disconnecting the 12-volt battery for 15 minutes. This will eliminate any remaining electric current, allowing your system to restart.

Before replacing the battery, it is essential to ensure it's of the correct type and size. The circuit board inside the fob's circuit board could be damaged when the replacement battery is too big or has an unrelated voltage. Before you install a battery you should clean the chip inside the fob to get rid of any harmful substances. The correct battery type will ensure that the key fob is sealed and protected against moisture. Once the key fob is been reinstalled it should function normally.
