Citroen C3 Key Fob Troubleshooting The Citroen c3 keyfob may stop working for a variety of reasons Some of these include worn buttons and poor contact with the battery water damage and receiver module problems Also you should check the 12 volt battery If your key fob does not unlock your car you could be experiencing deprogramming This happens when certain key sequences send a signal to the onboard computer to remove the key from its access list Dead coin battery If your Citroen C3s key fob has stopped working the first thing to examine is whether the battery is dead The batteries inside the fobs are small round coins that can be easily changed in a matter of seconds They are available at general stores home improvement stores and some auto parts stores Be sure to purchase the correct type though Fobs typically require CR2025 or CR2032 However it is recommended to check the owners manual to find out the specific kind of battery your vehicle requires Take off the button pad and then use cotton swabs or alcohol to clean it They will remove the corrosion and clean the contacts which are usually colored gold Once the contacts are cleaned you are able to put in the new battery Just be careful not to mix the two kinds because they differ in their voltages and diameters The next step is to test the voltage of the battery A multimeter that is calibrated to the batterys voltage range will give you a reliable reading If the battery shows an amount that is above or below its threshold it will need to be replaced Try getting your car started using a spare key however this might not work in all cases If G28 persists go to a CITROEN dealer with your V5 registration certificate and personal identification documents A CITROEN Dealer can locate the code of the immobiliser on your vehicle and purchase an upgrade to your battery Water damage If the key fob is under water it could lose its signal to the car Its best to remove it as fast as you can from the pool or puddle Once you have done that dry the circuit board as best you can using an abrasive swab of cotton thats been soaked in isopropyl alcohol or electronic cleaner If its still not working then its time for a new key fob Another common cause that can be the reason behind Citroen c3 remote control not working is signal interference This could happen if there is an electrical field close to the vehicle or other transmitters operating on the same frequency The key fob is expected to begin working once you leave the zone of interference The Citroen C3 key fob might stop working because of worn buttons problems with signal interference receiver module issues or a dead battery or a defective chip If this happens then youll have to have it replaced by a skilled technician This can be done by a trained mechanic or at an Citroen dealership If the issue is serious its time to have it replaced Its a relatively easy and inexpensive fix But you must take action quickly The longer you take to correct the issue the worse it will become If the issue isnt fixed it could pose a danger for you and your passengers Issue with the Receiver module If your key fob stops functioning it could be because the receiver module has developed an issue Water damage is among the numerous reasons This can happen when you drop your keys or wash them It is possible to repair the issue by removing the chip and cleaning it with isopropyl or electronic cleaner This will stop the chip from corroding You can also reset the receiver module if you disconnect it from the battery and then wait 10 seconds You can then reconnect the battery and repeat the process If this doesnt fix the issue take it to a retailer to be repaired Another reason why your key might stop working is due to interference This can be caused by other transmitters that operate on the same frequency as your key fob or by objects in your vehicle If you are unable to resolve the issue visit a dealer to get 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 display the message Key not detected This could be a major issue especially when trying to start your vehicle Dead 12 volt battery If your key fob ceases working after the battery has been changed the device could be damaged This is especially true when the key fob is dropped or stepped on but it also can occur after service on your car which requires the removal and reinstallation of panels When these panels are removed the wires are exposed If your fob was damaged it may require replacement completely Another possibility is that the remote is receiving interference from other devices or places This can cause RF signals to weaken and stop the car from recognizing the remote If this is the case you can reset all onboard computers by disconnecting the battery at 12 volts for around 15 minutes This will take away any remaining electrical energy allowing the system to restart Before replacing the battery it is important to ensure its the correct type and size If the battery you replace is too small or has an incompatible voltage it could harm the circuit board in the key fob Before installing a battery you must clean the chip inside the fob to remove any harmful substances Using the correct type of battery can help ensure that it is sealed and protected from moisture After the key fob has been put back in place it should function normal You should be able to use the second key even if your car displays a message saying key is not recognized It might be necessary to press the button multiple times before it responds
