Citroen C3 Key Fob Troubleshooting Citroen key fobs can cease to function due to a variety of causes The most common reasons are worn buttons that are not in contact with the battery water damage and receiver module issues It is also recommended to check the 12 volt battery Deprogramming could be the reason that your key fob isnt unlocking your car This happens when certain buttons send an electronic message to the computer requesting that the key be removed from its list of keys Dead coin battery If your Citroens C3s key fob has stopped working the first thing to check is if the battery is dead The batteries in the fobs are small round coins that can be easily replaced in a matter of minutes They are available at the general stores home improvement stores and even auto parts stores Make sure you buy the correct type though The batteries for fobs are usually CR2025 or CR2032 However you must consult the owners manual for your vehicle to determine which kind of battery is needed Remove citroen keys and use cotton swabs and alcohol to clean it These will help remove corrosion and clean the contacts which are typically goldcolored Once the contacts are cleaned you are able to add the new battery Just be careful not to mix the two types as they differ in their voltages and diameters The next step is to test the voltage of the battery A multimeter set to the batterys voltage range should provide a precise reading If the battery is at an amount that is above or below its threshold it will need to be replaced You could also try to start your car using an extra key but it may not be effective in all cases If the issue continues go to a CITROEN dealership with your V5 registration number and personal identification documents A CITROEN dealer can find the code of your vehicles immobiliser and can order the replacement battery Water damage If the key fob is submerged it may lose its signal It is best to remove it as fast as possible from the pool or puddle Once you do dry the circuit board in the best way you can using an abrasive swab of cotton thats been soaked in isopropyl alcohol or electronic cleaner If the key fob does not work it may be time to invest in a new one Signal interference is a common cause of Citroen remote control not working This may occur when there is an intense electrical field near the vehicle or from other transmitters on the same frequency When you leave the area of interference your key fob should start working again The Citroen C3 key fob might not function because of worn buttons problems with signal interference receiver module problems a dead 12volt battery or a malfunctioning chip Youll need to have it replaced if this happens This can be accomplished by a qualified mechanic or at an Citroen dealership If the issue is severe it may be necessary to replace it Its a fairly simple and affordable fix But you have to be quick to act The longer you put off fixing the issue the more difficult it gets It could pose a risk to you and your passengers when the issue is not addressed Issue with the Receiver module If your key fob ceases working it could be because the receiver module has developed an issue Water damage is among the numerous causes This could happen if you lose your keys or wash them You can try to fix the problem by removing and cleaning the chip with isopropyl alcohol 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 waiting for 10 minutes Then reconnect the battery to the car and repeat the process If this isnt enough to fix the issue take it to a dealer to be repaired Another reason your key could stop working is due to interference It can be caused by other transmitters using the same frequency or by objects in your vehicle If youre not able to fix the issue you can take your key fob to a dealer and have it replaced 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 will not recognize the car key and display a message telling you key not recognized This could be a frustrating issue especially when trying to start your vehicle Dead 12 volt battery It is possible that your key fob is damaged if it stops working after a change in batteries This is more common in the event that your key fob has been thrown around or stepped on but can also be the result of a service that requires the removal of panels and the reinstallation When the panels are removed the wires are exposed If your fob was damaged it may require replacement A fob that is receiving interference from other devices or locations is a second possibility This could cause RF signals to weaken and stop the car from acknowledging the remote If this is the case you can reset all computer systems on board by disconnecting the battery that is 12 volts for approximately 15 minutes This will remove any residual power allowing the system to reboot It is crucial to determine the size and type of the battery prior to replacing it If the replacement battery isnt big enough or has a different voltage it may damage the circuit board in the fobs key Before you install a battery you should clean the chip inside the fob in order to eliminate any contaminants that could cause corrosion Using the right type of battery will ensure that it is properly sealed and shielded from moisture Once the key fobs been reinstalled it will function normally It is usually possible to use the second key if your car displays a message stating key not found You may need to press the button a few times before it responds
