Once you do dry the circuit board in the best way you can with a cotton swab dipped in isopropyl alcohol or an electronic cleaner. If it still doesn't work It could be the right time to purchase a new key fob.

Another reason that can be cited one of the main reasons for Citroen remote control c3 not working is signal interference. This may occur when there is an intense electrical field near the vehicle or from other transmitters on the same frequency. The key fob will begin to function again after you are out of the zone of interference.

Another reason why your key might be unable to function is due interference. This could be caused by other transmitters that use the same frequency as your key fob or even objects in your vehicle. If you are unable to solve the issue, take your key fob in to an authorized dealer to 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 right, the receiver will not recognize the car key and display a message saying "key not detected". This can be a frustrating issue especially when you attempt to start your vehicle.

This will clear any residual power and allow the system to begin over.

Before replacing the battery, it is essential to ensure it's of the correct type and size. The circuit board inside the fob's key could be damaged when the battery you replace is too large or has a different voltage. You should also clean any corrosive materials off the chip inside the fob before installing the new battery.
