Citroen C3 Key Fob Troubleshooting The key fob of the Citroen C3 can stop working due to different reasons They can be due to worn buttons poor contact between the battery and the water and receiver module issues Check the 12 volt battery Deprogramming is a possible cause the key fobs inability to unlocking your car This happens when certain button combinations send an email 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 is dead Fobs have small coinshaped batteries that can be replaced in just a few minutes They are available at general stores home improvement stores and even auto parts stores Make sure you purchase the correct type though Batteries for fobs are typically CR2025 or CR2032 However you must consult the owners manual of your vehicle to determine which type is required Remove the button pad and then use cotton swabs or alcohol to clean it These will help remove corrosion and clean the contacts that are usually gold colored Once the contacts are cleaned you can then put in the new battery Be cautious not to mix the two batteries as they differ in voltage dimensions and shapes The next step is to examine the batterys voltage A multimeter that is set to the batterys voltage range will provide you with a precise reading If the battery is at a voltage that is higher or lower than its threshold it is required to be replaced Try starting your car with an extra key but this may not be successful in all instances If the issue continues visit an CITROEN dealer with your V5 registration certificate and personal identification documents A CITROEN dealer can find the code of your vehicles immobiliser and order the replacement battery Water damage If the key fob is submerged it may lose its signal If this occurs its a good idea to fish it out of the puddle pool or washing machine as quickly as you can Once you do dry the circuit board in the best way you can using the help of a cotton swab dipped into isopropyl alcohol or electronic cleaner If the key fob does not work it may be time to invest in an additional one Signal interference is a different cause of Citroen remote controls not working It can happen when there is an electrical field close to the car or other transmitters that operate on the same frequency Once you leave the interference area your key fob should start working again Lastly the Citroen c3 key fob can stop working due to worn buttons signal interference receiver module issues or a dead 12 Volt battery or a damaged electronic chip Youll need to have it reprogrammed in the event of this This can be done either by a qualified mechanic or a Citroen dealer If the problem is severe then youll have to get it replaced Its a relatively easy and affordable fix But G28 must be quick to act The longer you wait to fix the issue the more difficult it becomes It could be dangerous for passengers and yourself when the issue is not addressed Issue with the Receiver module If your key fob stops working it could be because the receiver module has developed a fault This could be due to several things that include water damage This can happen if you drop your keys or wash them You can try to resolve the issue by removing and cleaning the chip with isopropyl ethanol or electronic cleaner This will keep the chip from corroding You can also try to reset the receiver module by disconnecting it from the car battery and letting it sit for 10 seconds You can then reconnect the battery and repeat the procedure If this doesnt resolve the issue visit a dealership to get it replaced Another reason why your key might be unable to function is due interference It could be caused by other transmitters that operate on the same frequency as your key fob or by objects in your vehicle If youre unable to fix the issue you can visit a dealer and change the key fobs programming 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 is not right the receiver will not recognize the car key and display a message saying key not detected This can be a gruelling problem especially when youre trying to start your vehicle Dead 12 volt battery It is possible that your key fob has been damaged if it ceases to function after changing batteries This is more likely if your key fob has been dropped or stepped upon but can also be the result of a service that requires the removal of panels and the reinstallation Wires are exposed when these panels are removed If your fob has been damaged it might require replacement completely A fob that is receiving interference from other devices and locations is also a possibility This could cause the RF signals to weaken and block the car from recognizing the remote You can reset your onboard computer if this is the situation by disconnecting the 12volt battery for 15 minutes This will erase any remaining electricity allowing the system to reboot It is important to check the size and type of the battery prior to replacing it If the replacement battery isnt big enough or has an incompatible voltage it could damage the circuit board inside the fobs key You should also clean any corrosive material from the chip in the fob before installing a new battery Making sure you choose the right battery can help ensure that it is sealed and protected from moisture After the key fob has been reinstalled it should function normally In the majority of instances you can use the second key to start your vehicle even if it shows a message of key not found You may need to press the button several times before it responds
