Citroen C3 Key Fob Troubleshooting
Citroen c3 key fobs can cease to function due to different reasons. The most common reasons are worn buttons that are not in contact with the battery, water damage, and receiver module problems. You should also check the battery's 12 volts.
If your key fob does not unlock your car, it could be experiencing deprogramming. This happens when certain buttons send an electronic message to the 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 working, first determine if the battery is dead. The batteries in the fobs are tiny, round coins that can be replaced within a few moments. They are available at home improvement stores, as well as some auto parts stores. Make sure you purchase the right type. The majority of fobs require CR2025 or CR2032 however, you must refer to the owner's manual of your vehicle to see the exact type of battery your car requires.
Take off 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 insert the new battery. Be careful not to mix the two batteries as they have different voltages, sizes and diameters.
The next step is to test the battery's current voltage. You can get an accurate reading with a multimeter that is set to the battery voltage range. If the battery has a value above or below its threshold, it has to be replaced. You could also start your car with a spare key. However, this might not always work. If the problem persists, visit a CITROEN dealer with your V5 registration form and personal identification documents. A CITROEN Dealer can locate the code for your vehicle's immobiliser and order a new battery.
Water damage
When the key fob gets under water, it could lose its signal to the car. If this happens, it's a good idea to remove it from the pool, puddle, or washing machine as quickly as possible. Once you've done that make use of an swab of cotton and isopropyl or electronic cleaner to dry the circuit board. If the key fob does not work, it may be time to buy an additional one.
Another reason that can be cited the most common reason for Citroen remote control c3 not working is signal interference. It can happen when there is an intense electrical field that is close to the car, or from other transmitters operating on the same frequency. Once you leave the area of interference, your key fob will begin working again.
The Citroen C3 key fob could be inoperable due to worn buttons or signal interference issues, receiver module issues or a dead 12-volt battery or a malfunctioning chip. You'll need to have it replaced if this happens. This can be done by a trained mechanic or a Citroen dealer. If the problem is serious, you may need to replace the device. This is a fairly easy and inexpensive fix, but it's essential to act quickly. The longer you take to correct the issue the more deteriorated it becomes. If the issue isn't resolved, it can be dangerous for the passengers and yourself.
Receiver Module Issue
If your key fob ceases functioning, it could be due to the receiver module having developed an issue. Water damage is among the numerous reasons. This can occur when you lose your keys or wash them. You can try to fix the issue by taking off and cleaning the chip with isopropyl ethanol or electronic cleaner. This will prevent corrosion of the chip.
You can also reset the receiver module when you disconnect it from the battery and then wait 10 seconds. Then, reconnect the battery and repeat the process. If this doesn't resolve the issue, you can visit a dealership to get it replaced.
Another reason your key may stop working is due to interference. It could be caused due to other transmitters that use the same frequency as your key fob or by objects within your vehicle. If you're unable to fix the issue, visit a dealer to change the key fob's programming.
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 is not accurate the receiver won't recognize the car key and display a message stating "key not recognized". This could be a major issue particularly when trying to start your car.
Dead 12 volt battery
It is possible that your key fob has been damaged if it ceases to function after a change of batteries. This is especially common when the key fob has been dropped or stepped on. However, it can also happen following servicing on your car which requires the removal and reinstallation of panels. When the panels are removed, the wires are exposed. If your fob is damaged, you may need to replace it completely.
A remote that receives interference from other devices and locations is another possibility. This can make RF signals weaker and block the car from being able to recognize the remote. You can reset the onboard computer if this is the situation. You can do this by disconnecting the 12-volt battery for 15 minutes. This will take away any remaining power, allowing the system to reboot.
www.g28carkeys.co.uk is essential to verify the size and quality of the battery prior to replacing it. If the replacement battery is too small or has an unsuitable voltage, it could damage the circuit board inside the key fob. It is also recommended to clean any corrosive material from the chip in the fob prior to installing a new battery. Making sure you choose the right battery will ensure that it is properly sealed and protected from moisture. Once the key fob has been reinstalled, it will function normally. In most instances, you will be able to use the second key to start your car when it displays a message of "key not detected." You may have to press the button a few times before it responds.
