Next, you will need to check the voltage of the battery. You can get a reliable reading using a multimeter, which is set to the battery's voltage range. If the battery has a voltage that is higher or lower than its threshold, it has to be replaced. You can also start your vehicle using a spare key. However, this might not always work.

Water damage

If the key fob is submerged, it may lose its signal. It's best to remove it as fast as you can out of the pool or puddle. After this then use a cotton swab and isopropyl or electronic cleaner to clean the circuit board. If the key fob still isn't working, it could be time to get an additional one.

Another common cause that can be the reason behind Citroen remote control c3 not working is signal interference. It can happen when there is a strong electrical field near the vehicle or from other transmitters on the same frequency. The key fob should begin to function again after you have left the zone of interference.

The citroen c1 spare key cost C3 key fob can stop working because of worn buttons signals, signal interference issues receiver module problems as well as a dead 12-volt battery or a defective chip.

Receiver Module Issue

If your key fob is not functioning, the receiver module may have developed an issue. This can be caused by a number of things like water damage. This can happen if you drop your keys or wash them. You can fix the issue by taking off and cleaning the chip with isopropyl ethanol or electronic cleaner. This will help to keep the chip from getting damaged.

You can also try to reset the receiver module by disconnecting it from the car battery and then waiting for 10 seconds. Then, reconnect the battery and repeat the procedure. If this doesn't fix the issue, visit a dealership to have it replaced.

You can reset the on-board computer if this is the situation, by disconnecting the 12-volt battery for 15 minutes. This will take away any remaining electrical energy, allowing the system to restart.

Before replacing the battery it is essential to ensure it's of the correct size and type. If the replacement battery is too small or has a different voltage, it can damage the circuit board within the fob's key. You should also clean any corrosive substances from the chip in the fob before installing the new battery.
