Before you replace the battery, remove the button pad and rub it with cotton swabs or alcohol. This will help remove corrosion and clean the contacts which are usually colored gold. Once the contacts are cleaned then you can put in the new battery. Be careful not to mix up the two types since they have different voltages, dimensions, and shapes.

The next step is to test the battery's voltage. You can get an accurate reading with a multimeter that is set to the battery voltage range. If the battery shows a voltage that is higher or lower than its threshold, it will need to be replaced. You could also start your car using a spare key. However, this might not always work. If the problem persists visit an CITROEN dealership with your V5 registration number and personal identification documents. A citroen key code dealer can locate the code for the immobiliser on your vehicle and request a replacement battery.

Water damage

If the key fob is submerged it may lose its signal. If this happens, it's a great idea to get it out of the pool, puddle or washing machine as fast as you can. After you've done this using an swab of cotton and isopropyl or electronic cleaner to dry the circuit board. If the circuit board is still not working, it may be the right time to purchase a new key fob.

Signal interference is a different cause of Citroen remote controls not working. This could happen if there is an electrical field in the vicinity of the vehicle or other transmitters using the same frequency. The key fob should begin working again after you leave the area of interference.

If your key fob stops working, it could be because the receiver module has developed a fault. Water damage is one of the numerous causes. This can happen when you accidentally drop your keys or wash them. You can try to resolve the issue by removing and cleaning the chip using isopropyl alcohol, or electronic cleaner. This will help to prevent corrosion of the chip.

You can also reset the receiver module by disconnecting it from the car battery and letting it sit for 10 minutes. Then, reconnect the battery and repeat the procedure. If this doesn't solve the issue, you can go to a dealer to have it replaced.
