Citroen C3 Key Fob Troubleshooting The Citroen c3 keyfob may not function for various reasons These include worn buttons poor contact between the battery and the water and receiver module issues Also you should check the 12 volt battery If your key fob does not unlock your car you might be experiencing deprogramming This occurs when certain buttons send a signal to the onboard computer to erase the key from its list of access Dead coin battery If the key fob on your Citroen C3 is no longer working first make sure the battery has gone out Fobs are small coinsshaped batteries that can be replaced in just a few minutes They are available in general stores home improvements stores and auto parts stores Make sure you buy the correct type though Batteries for fobs are usually CR2025 or CR2032 however you should refer to the owners manual of your vehicle to determine what kind of battery is needed Before replacing the battery take off the button pad and rub it with cotton swabs and alcohol This will help remove corrosion and clean the contacts which are usually colored gold After the contacts have been cleaned you are able to insert the new battery Be careful not to mix up the two types as they differ in voltage diameters and shapes The next step is to test the batterys current voltage You can obtain a precise reading using a multimeter which is calibrated to the batterys voltage range If the batterys voltage is in the middle or above the threshold then it needs to be replaced You can also try getting your car started using an additional key however this may not work in all cases If the issue continues you should visit a CITROEN dealer with your V5 registration document and personal identification documents A CITROEN dealer can locate the code for your vehicles immobiliser and get an alternative battery G28 If the key fob is submerged it could lose its signal Its best to remove it as soon as possible from the puddle or pool After youve done this use an swab of cotton and isopropyl or electronic cleaner to dry the circuit board If its still not working It could be the time to replace your key fob Signal interference is another common cause of Citroen remote control not working This could happen when there is a strong electrical field close to the car or from other transmitters on the same frequency Once you have left the interference area your key fob should start working again Lastly the Citroen C3 key fob could 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 replaced if this happens This can be done by a skilled mechanic or at a Citroen dealership If the problem is serious you may have to replace the device This is a fairly easy and inexpensive fix but its important to act quickly The longer you delay to correct the issue the more serious it will get It can be dangerous to you and your passengers If the issue isnt solved Receiver Module Issue If your key fob isnt functioning it could be because the receiver module might have developed a fault Water damage is one of the many causes This could happen if you lose your keys or wash them You can fix the problem by removing and cleaning the chip with isopropyl ethanol or electronic cleaner This will help to keep the chip from getting damaged You can also reset the receiver module by disconnecting it from the car battery and letting it sit for 10 seconds Then reconnect the battery to the car and repeat the process If this fails to fix the issue go to a dealer to have it replaced Another reason why your key could stop working is due interference It could be caused by other transmitters using the same frequency as your key fob or by objects in your vehicle If youre unable to fix the problem you can 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 doesnt match the receiver module wont recognize the key and display a message that says Key Not Detected This can be a frustrating issue especially when you attempt to start your car Dead 12 volt battery If your key fob ceases working after a battery change the device could be damaged This is more likely when your key fob has been dropped or stepped upon or stepped on but it could also be the result of 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 require replacement completely Another possibility is that the remote is receiving interference from other devices or places This can cause RF signals to become weaker and block the cars recognition of the remote If this is the case you can reset all onboard computers by disconnecting the battery at 12 volts for approximately 15 minutes This will clear any residual power and allow the system to restart from scratch It is crucial to determine the size and type of the battery before replacing it The circuit board that is inside the fobs key can become damaged when the battery you replace is too big or has an incompatible voltage Before installing a battery you should clean the chip of the fob in order to eliminate any corrosive substances The proper type of battery will ensure that the key fob is sealed and protected against moisture After the key fob has been installed it will function normal It is possible to use the second key if your car displays a message that says key not detected You may need to press the button a few times before it responds
