Dead coin battery
If the fob that you use to open the door on your Citroen C3 is no longer working, check first if the battery has died. The batteries in the fobs are small round coins that can be easily replaced within a few moments. They are sold in general stores, home improvement stores and auto parts stores. Make sure you buy the correct one, however. Batteries for fobs are usually CR2025 or CR2032, however, you should consult the owner's manual of your vehicle to determine what type is required.
Remove the button pad, and use cotton swabs and alcohol to clean it. These will help remove corrosion and clean the contacts, which are typically colored gold. Once the contacts have been cleaned, it is now time to add the new battery. Just be careful not to mix the two types because they differ in their voltages and diameters.
The next step is to assess the voltage of the battery. A multimeter calibrated to the battery's voltage range will give you a reliable reading. If the battery is at a value above or below its threshold, it is required to be replaced. You may also try getting your car started using an extra key, but it may not work in all situations. If the issue persists, visit a citroen Nemo key dealership with your V5 registration and identification documents. A citroen ds3 replacement key dealer will be able to retrieve the code for your vehicle's immobiliser system, and purchase an alternative battery.
Water damage
When the key fob goes underwater it may lose its signal to the car. If this occurs, it's a good idea to fish it out from the pool, puddle, or washing machine as soon as you can. After this make use of the cotton swab along with isopropyl or electronic cleaner to clean the circuit board. If the circuit board is still not working, it may be the right time to purchase a new key fob.
Another reason that is commonly cited one of the main reasons for Citroen c3 remote control not working is signal interference. This may occur when there is an intense electrical field near the car, or from other transmitters on the same frequency. When you leave the interference area your key fob should be working normally again.
Lastly, the citroen berlingo key fob C3 key fob might stop working due to worn buttons and receivers, signal interference, module issues or a dead 12 Volt battery, or a malfunctioning electronic chip. You'll have to get it replaced if this happens. This can be done by a trained mechanic or at a Citroen dealership. If the issue is significant it may be necessary to replace the device. It's a relatively easy and inexpensive fix. But you must get it done quickly. If you put off fixing the issue, the worse it becomes. It could pose a risk to passengers and yourself when the issue is not solved.
Issue with the Receiver module
If your key fob stops functioning, it could be because the receiver module has developed an issue. This can be caused by various factors that include water damage. This could happen if you lose your keys or wash them. You can repair the issue by removing the chip and cleaning it with isopropyl or an electronic cleaner. This will keep the chip from becoming corroded.
You can also reset the receiver module when you disconnect it from the battery for 10 seconds. Then, reconnect the battery to the car and repeat the procedure. If this doesn't resolve the issue, go to a dealer to have it replaced.
Another reason why your key could stop working is due to interference. This can be caused either by other transmitters using the same frequency or objects in your vehicle. If you are unable to resolve the problem, you can go to a dealership to have your key fob reset.
The key fob contains a short-range radio transmitter/radio-frequency identification (RFID) chip and antenna, which sends a distinct coded signal to the receiver module in your car. If the signal isn't correct the receiver module will not recognize the key and will display a message that says "Key Not Detected. This can be a gruelling problem, especially when you're trying to start your car.
Dead 12 volt battery
If your key fob ceases working after the battery has been changed the device could be damaged. This is most likely to happen in the event that the key fob was dropped or stepped on, but it also can occur after servicing on your car which requires the removal and reinstallation of panels. Wires become exposed when panels are removed. If your fob is damaged, you might require replacement completely.
Another possibility is that the remote is getting interference from other devices or places. The RF signals can cause to weaken and block the car from recognizing the remote. If this is the case you can reset the on-board computers by disconnecting the battery with 12 volts for approximately 15 minutes. This will eliminate any remaining electricity, allowing the system to restart.
Before replacing the battery it's important to make sure that it's the right type and size. If the replacement battery is too small or has an incompatible voltage, it may damage the circuit board in the fob's key. You should also remove any corrosive materials off the chip in the fob prior to installing the new battery. The correct type of battery can ensure that the key fob is sealed and protected from moisture. Once the key fob is reinstalled, it should work normal. You can usually use the second key if your car displays a message saying "key is not recognized." It is possible to press the button a few times before it responds.
