Citroen C3 Key Fob Troubleshooting Citroen c3 key fob can stop working for a variety of reasons. These include worn buttons poor contact with the battery, water damage and receiver module issues. It is also recommended to check the 12 volt battery. Deprogramming could be the cause of your key fob not unlocking your car. This occurs when certain buttons send a signal to the onboard computer to erase the key from its access list. Dead coin battery If your Citroen's C3's key fob is not working, the first thing to check is if the battery is dead. The batteries in the fobs are small, round coins that can be replaced within a few moments. You can find these at general stores, home improvement stores, and even auto parts stores. Be sure to purchase the correct type, though. Fobs usually require CR2025 or CR2032, but you should refer to the owner's manual of your vehicle to determine the type of battery that your car requires. Remove the button pad and use cotton swabs and alcohol to clean it. These will help remove corrosion and clean the contacts that typically have a gold color. Once the contacts are cleaned then you can put in the new battery. Be careful not to mix up the two kinds as they differ in voltage, sizes and diameters. Next, you will need to determine the voltage of the battery. A multimeter calibrated to the battery's voltage range should give you an accurate reading. If the battery is at an amount that is above or below its threshold, it has to be replaced. You may also try the car's start using a spare key, however this might not be successful in all instances. If the problem persists go to an CITROEN dealership with your V5 registration and personal identification documents. A CITROEN dealer can obtain the code for your vehicle's immobiliser and order a replacement battery. Water damage When the key fob gets submerged, it could lose its signal to the car. If this occurs, it's a good idea to fish it out from the pool, puddle or washing machine as fast as possible. After that dry the circuit board as well as you can with the help of a cotton swab, dipped into isopropyl ethanol or electronic cleaner. If it still doesn't work, it may be time for a new key fob. Signal interference is another frequent cause of Citroen remote controls not working. This could happen if there is an electrical field in the vicinity of the car or other transmitters operating on the same frequency. The key fob will begin to work again once you are out of the area of interference. The Citroen C3 key fob might cease to function due to worn buttons or signal interference issues, receiver module issues or a dead battery or a damaged chip. citroen c3 keys 'll have to get it changed to a new program in the event of this. This can be accomplished by a qualified mechanic or a Citroen dealer. If the issue is serious, you may need to replace it. It's a relatively easy and affordable fix. But you have to get it done quickly. If you put off fixing the problem, the worse it gets. If the issue isn't fixed the issue could be a hazard for the passengers and yourself. Receiver Module Issue If your key fob isn't working, the receiver module may have developed a fault. It could be caused by a number of things like water damage. This could happen if you drop your keys, or wash them. It is possible to solve the problem by removing your chip and cleaning it with isopropyl or an electronic cleaner. This will stop the chip from corroding. You can 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 fails to fix the issue, you can visit a dealership to get it replaced. Interference can also cause your key to stop working. It can be caused by other transmitters operating on the same frequency or objects in your vehicle. If you are unable to resolve the issue, you can go to a dealership to change the key fob's programming. 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 in order the receiver module will not recognize the key and display an error message that states the key is not detected. This is a problem that can be frustrating particularly when trying to start your vehicle. Dead 12 volt battery If your key fob ceases working after an upgrade to a battery, it may be damaged. This is most likely to happen if the key fob was dropped or stepped on. However, it also can occur after maintenance on your vehicle that requires removal and reinstallation of panels. When these panels are removed, wires are exposed. If your fob is damaged, you might require a complete replacement. A remote that is receiving interference from other devices and locations is a different possibility. This can make RF signals less effective and hinder the car from recognizing the remote. If this happens you can reset the on-board computers by disconnection of the battery that is 12 volts for around 15 minutes. This will erase any remaining power, allowing the system to reboot. It is essential to verify the size and type of the battery prior to replacing it. If the battery you replace isn't big enough or has an unsuitable voltage, it could harm the circuit board inside the fob's key. Before you install a battery you should clean the chip of the fob to remove any contaminants that could cause corrosion. The correct battery type will ensure that the key fob is sealed and protected from moisture. After the key fob has been reinstalled, it should function normally. It is possible to use the second key in the event that your vehicle displays a message that reads “key not found.” It is possible to press the button a few times before it responds.
