Once the contacts are cleaned then you can put in the new battery. Be cautious not to mix the two types as they differ in voltage, dimensions and shapes.

The next step is to test the battery's voltage. You can obtain a precise reading using a multimeter that is set to the battery's voltage range. If the battery shows a voltage that is higher or lower than its threshold, it is required to be replaced. You could also try starting your car with an additional key, however this may not be successful in all instances. If the issue persists, visit an citroen berlingo key fob dealership with your V5 registration as well as personal identification documents.

Water damage

If the key fob is submerged it can lose its signal. If this occurs, it's a good idea to fish it out from the pool, puddle or washing machine as fast as possible. Once you do, dry out the circuit board as much as you can with a cotton swab dipped in isopropyl ethanol or electronic cleaner. If the key fob isn't working, it may be time to get another one.

Signal interference is another frequent cause of Citroen remote control not working. This could happen if there is an electrical field in the vicinity of the vehicle or other transmitters that operate on the same frequency. The key fob should start working again after you have left the zone of interference.

The Citroen C3 key fob might stop working because of worn buttons signals, signal interference issues receiver module issues or a dead battery or a malfunctioning chip.

You can try to fix the problem by removing and cleaning the chip using isopropyl alcohol, or electronic cleaner. This will stop the chip from getting corroded.

You can also reset the receiver module if you disconnect it from the battery and wait 10 seconds. Then, reconnect the battery to the car and repeat the procedure. If this doesn't solve the issue, you can go to a dealer to have it replaced.

Another reason your key could stop working is due to interference. This can be caused by 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, go to a dealership to get your key fob reprogrammed.

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 will not recognize the key and display an error message that states the key is not detected. This could be a frustrating issue, particularly when trying to start your vehicle.

This will remove any residual electrical energy, allowing the system to reboot.

It is essential to verify the size and quality of the battery before replacing it. The circuit board that is inside the fob's key could be damaged in the event that the replacement battery is too large or has different voltage. Before you install a battery you should clean the chip of the fob in order to eliminate any corrosive substances. The right battery type can ensure that the key fob is sealed and protected against moisture. Once the key fob has been reinstalled, it will function normally. It is possible to use the second key even in the event that your vehicle displays a message that says "key not found." You may need to press the button several times before it responds.
