Citroen C3 Key Fob Troubleshooting Citroen c3 key fob can stop working due to many reasons Some of these include worn buttons or poor contact with the battery water damage and receiver module issues You should also check the batterys 12 volts If the key fob will not unlock your car you could be experiencing deprogramming This happens when certain button combinations send an alert to the onboard computer asking that the key be removed from its list of keys Dead coin battery If the fob that you use to open the door on your Citroen C3 is no longer functioning first check if the battery has died The batteries in the fobs are small round coins that can be replaced in a matter of minutes They are available in general stores home improvements stores and auto parts stores Make sure you purchase the right type Batteries for fobs are usually CR2025 or CR2032 however you must consult the owners manual of your vehicle to determine what kind is required Before you replace the battery take off the button pad and rub it with cotton swabs and alcohol This will help remove corrosion and clean the contacts that typically have a gold color After the contacts have been cleaned it is now time to add the new battery Be careful not to mix up the two types since they differ in voltage sizes and diameters The next step is to check the batterys voltage A multimeter set to the batterys voltage range should provide you with a precise reading If the batterys current value is above or below threshold it should be replaced You can also try the cars start using an additional key however this might not be effective in all cases If the issue continues visit a CITROEN dealership with your V5 registration and personal identity documents A CITROEN Dealer can locate the code for your vehicles immobiliser and then order an upgrade to your battery Water damage If the key fob is submerged it may lose its signal If this occurs its a good idea to remove it of the pool puddle or washing machine as soon as you can Once you have done that dry out the circuit board as best you can with a cotton swab that has been dipped in isopropyl alcohol or an electronic cleaner If citroen key immobiliser is still not working it may be time for a new key fob Signal interference is a different cause of Citroen remote control not working This may occur when there is a strong electrical field close to the car or from other transmitters operating on the same frequency The key fob should begin working once you have left the zone of interference Finally the Citroen c3 key fob can stop working due to worn buttons or signal interference receiver module issues or a dead 12 Volt battery or a malfunctioning electronic chip It will need to be changed to a new program when this happens This can be accomplished by a qualified mechanic or at an Citroen dealership If the issue is serious you may have to replace the device Its a simple and affordable fix But you must be quick to act The longer you wait to fix the issue the more serious it gets If the issue isnt resolved it can be dangerous for you and your passengers Receiver Module Issue If your key fob ceases working it might be due to the receiver module having developed a fault Water damage is among the numerous reasons This can occur when you drop your keys or wash them You can attempt to fix the issue by taking off and cleaning the chip with isopropyl alcohol or electronic cleaner This will keep the chip from corroding You can also reset the receiver module by disconnecting it from the car battery and then waiting for 10 minutes Then reconnect the battery and repeat the procedure If this doesnt fix the issue visit a dealership to have it replaced Interference can also cause your key to stop working This can be caused either by other transmitters using the same frequency or objects in your vehicle If youre unable fix the issue go to a dealer to have your key fob reprogrammed The key fob contains a shortrange radio transmitterradiofrequency identification RFID chip and antenna which sends a distinct coded signal to the receiver module in your car If the signal isnt right the receiver module wont recognize the key and will display a message that says Key Not Detected This can be a frustrating problem especially when trying to start your car Dead 12 volt battery If your key fob ceases working after an upgrade to a battery it could be damaged This is more likely when your key fob has been thrown or stepped on but can also occur after a service that requires the removal of the panels and reinstallation When these panels are removed wires are exposed If your fob is damaged you may have to replace it completely Another possibility is that the fob is receiving interference from other devices or places This could make RF signals weaker and hinder the cars recognition of the remote You can reset the onboard computer in this scenario by disconnecting your 12volt battery for 15 minutes This will eliminate any remaining electrical charge and allow the system to begin from scratch It is essential to verify the size and type of the battery before replacing it If the battery you replace is too small or has an incompatible voltage it could harm the circuit board within the fobs key It is also recommended to clean any corrosive material from the chip in the fob prior to installing a new battery Using the right type of battery can help ensure that it is sealed and protected from moisture Once the key fob is been installed it should work normally You can usually use the second key in the event that your vehicle displays a message that says key not found It is possible to press the button a few times before it responds
