Next, you will need to test the voltage of the battery. You can obtain a precise reading using a multimeter, which is calibrated to the battery's voltage range.

Another reason that can be cited one of the main reasons for citroen relay key fob c3 remote control not working is signal interference. This may occur when there is an intense electrical field near the car or from other transmitters operating on the same frequency. The key fob is expected to begin to work again once you leave the zone of interference.

The Citroen C3 key fob could stop working because of worn buttons signals, signal interference issues receiver module issues, a dead 12-volt battery or a damaged chip.

Receiver Module Issue

If your key fob isn't functioning, the receiver module may have developed a fault. It could be caused by several things like water damage. This can happen if you drop your keys, or wash them. You can try to solve the problem by removing your chip and cleaning it with isopropyl, or electronic cleaner. This will prevent corrosion of the chip.

You could also try to reset the receiver module by disconnecting it from the car battery and waiting for 10 minutes. Then, reconnect the battery and repeat the process. If this doesn't fix the issue, bring it to a dealer to have it replaced.

This will eliminate any remaining electricity and allow the system to restart over.

Before replacing the battery, it is important to ensure it is the correct type and size. If the battery you replace isn't big enough or has an unsuitable voltage, it could harm the circuit board inside the key fob. Before installing a battery you must clean the chip inside the fob to eliminate any contaminants that could cause corrosion.
