Citroen C3 Key Fob Troubleshooting Citroen key fobs can stop working due to a number of causes. These include worn buttons poor battery contact, water damage and receiver module problems. Check the 12 volt batteries. If the key fob will not unlock your car, it could be experiencing deprogramming. This happens when certain buttons send an email to the onboard computer, asking that the key be removed from its list of keys. Dead coin battery If your Citroen C3's main fob isn't working the first thing to check is if the battery is dead. Fobs utilize small, coin-shaped batteries that can be replaced within a few minutes. You can find these at home improvement stores, and a few auto parts stores. Be sure to buy the correct kind. Batteries for fobs are typically CR2025 or CR2032 However you must consult the owner's manual of your vehicle to determine which kind of battery is needed. Before replacing citroen key remote , take off the button pad and rub it with cotton swabs and alcohol. They will remove the corrosion and clean the contacts which typically have a gold color. Once the contacts have been cleaned it is time to insert the new battery. Be careful not to mix the two types as they differ in voltage, dimensions, and shapes. The next step is to check the battery's voltage. You can get a reliable reading using a multimeter which is set to the battery voltage range. If the battery has a value above or below its threshold, it has to be replaced. You can also start your car using a spare key. However, this may not always work. If the problem persists then visit a CITROEN dealer with your V5 registration certificate and personal identification documents. A CITROEN Dealer can retrieve the code of the immobiliser on your vehicle and purchase new batteries. Water damage When the key fob gets under water, it could lose its signal to the car. It is best to remove it as quickly as you can out of the pool or puddle. After that dry the circuit board as well as you can using an abrasive swab of cotton that's been soaked in isopropyl alcohol or electronic cleaner. If the circuit board is still not working It could be the time to replace your key fob. Another common reason for Citroen c3 remote control not working is signal interference. This could happen when there is a strong electrical field near the car, or from other transmitters operating on the same frequency. When you leave the interference area the key fob will begin working again. The Citroen C3 key fob might stop working because of worn buttons signals, signal interference issues receiver module issues as well as a dead 12-volt battery or a malfunctioning chip. You'll need to have it reset when this happens. This can be done by a certified mechanic or at an Citroen dealership. If the issue is serious it may be necessary to replace it. It's a simple and inexpensive fix, but it's imperative to act swiftly. The longer you wait to fix the issue, the more severe it will be. If the problem isn't addressed it could be a risk for passengers and you. Receiver Module Issue If your key fob ceases working, it could be due to the receiver module having developed a fault. This can be caused by various factors such as water damage. This can happen when you drop your keys or wash them. You can try to fix the problem by taking off the chip and cleaning it with isopropyl, or electronic cleaner. This will stop the chip from getting corroded. You can also reset the receiver module by disconnecting it from the car battery and waiting for 10 seconds. Then reconnect the battery to the car and repeat the process. If this isn't enough to fix the problem, you can bring it to a dealer for replacement. Interference can also cause your key to stop working. This can be caused either by other transmitters operating on the same frequency, or by objects inside your vehicle. If you are unable to resolve the issue, you can visit a dealer and have your key fob reset. 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 correct the receiver will not recognize the car key and display a message telling you “key not detected”. This could be a frustrating issue, especially when trying to start your car. Dead 12 volt battery If your key fob ceases working after a battery change, it may be damaged. This is most likely to happen when the key fob has been dropped or stepped upon, but it could also occur following maintenance on your vehicle that requires the removal and reinstallation of the panels. Wires are exposed when these panels are removed. If your fob was damaged, it may need to be replaced entirely. Another possibility is that the remote receives interference from other devices or locations. This can make the RF signals less effective and hinder the car's recognition of the remote. You can reset the on-board computer if this is the scenario by disconnecting your 12-volt battery for 15 minutes. This will eliminate any remaining electricity, allowing the system to reboot. Before replacing the battery, it is essential to ensure that it's the right type and size. The circuit board that is inside the key fob can be damaged if the replacement battery is too large or has an unrelated voltage. It is also recommended to clean any corrosive substances from the chip inside the fob before installing the new battery. The correct battery type will ensure that the key fob is sealed and protected against moisture. Once the key fob has been reinstalled, it should function normally. In the majority of instances, you will be able to use the second key to start your car, even when it displays an error message that reads “key not found.” You may have to press the button a few times before it responds.
