Citroen C3 Key Fob (Http://Www.Softjoin.Co.Kr/Gnu5/Bbs/Board.Php?Bo_Table=Qa&Wr_Id=1363650) Troubleshooting

Citroen c3 key fob can stop working for various reasons. There are a variety of reasons, including worn buttons that are not in contact with the battery, water damage and receiver module issues. You should also examine the battery's 12 volts.

Deprogramming could be the reason the key fob's not unlocking your car. This occurs when certain button combinations send an electronic message to the computer requesting that the key be removed from its list of keys.

Dead coin battery

If your Citroen C3's key fob is not working the first thing you should determine is if the battery is dead. Fobs have small coins-shaped batteries that can be replaced in a few minutes. They are sold in general stores, home improvements stores and auto parts stores. Be sure to buy the correct type. Fobs typically require CR2025 or CR2032 however, you must look through the owner's guide to determine the type of battery your car requires.

Before you replace the battery, remove the button pad and rub it with cotton swabs and alcohol. These will help remove corrosion, and clean the contacts, which typically have a gold color. After cleaning the contacts and sanitized, you can then insert the new battery. Be careful not to mix up the two kinds as they have different voltages, diameters and shapes.

The next step is to check the battery's voltage. You can get an accurate reading using a multimeter which is set to the battery voltage range. If the battery has an amount that is above or below its threshold, it needs to be replaced. You could also start your car with a spare key. However, this may not always work. If the issue continues, visit a CITROEN dealership with your V5 registration as well as personal identity documents. A CITROEN Dealer can retrieve the code for your vehicle's immobiliser, and then order new batteries.

Water damage

If the key fob is submerged it could lose its signal. It is best to remove it as fast as you can out of the pool or puddle. After this, use an swab of cotton and isopropyl or electronic cleaner to clean the circuit board. If it doesn't work, it may be time to get a new key fob.

Signal interference is a common reason for Citroen remote controls not working. This can occur when there is an electrical field near the car or other transmitters on the same frequency. Once you leave the area of interference, your key fob will be working normally again.

The Citroen C3 key fob can cease to function due to worn buttons, signal interference issues, receiver module issues, a dead 12-volt battery or a defective chip. If this happens, you'll likely require it to be changed by a certified expert. This can be done by a trained mechanic or at an citroen key replacement cost dealership. If the problem is serious you may have to replace it. It's a simple and inexpensive fix. But you have to take action quickly. The longer you delay to resolve the issue, the more serious it will get. If the issue doesn't get resolved the issue could be a hazard for you and your passengers.

Issue with the Receiver module

If your key fob is not functioning the receiver module could have developed an issue. It could be caused by a number of things such as water damage. It can happen when you drop your keys, or wash them. You can resolve the issue by removing and cleaning the chip using isopropyl alcohol, or electronic cleaner. This will help to keep the chip from getting damaged.

You can reset the receiver module if you disconnect it from the battery, and wait 10 seconds. Then, reconnect the battery to the vehicle and repeat the process. If this doesn't fix the issue, visit a dealership to get it replaced.

Another reason your key could be unable to function is due interference. It could be caused by other transmitters operating on the same frequency, or by objects in your vehicle. If you are unable to fix the issue, bring your key fob to an authorized dealer to have it 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 is not accurate the receiver will not recognize the car key and display a message that reads "key not detected". This can be a gruelling problem, especially when you're trying to start your vehicle.

Dead 12 volt battery

If your key fob ceases working after the battery has been changed it could be damaged. This is more likely if your key fob has been thrown around or stepped on or stepped on, but it could also occur following a repair that requires the removal of panels and reinstallation. When these panels are removed, wires are exposed. If your fob was damaged, it might require replacement completely.

A fob that is receiving interference from other devices and locations is a different possibility. This can cause RF signals to become less effective and hinder the car from recognizing the remote. If this is the case, you can reset all on-board computers by disconnection of the battery that is 12 volts for around 15 minutes. This will clear any residual power and allow the system to start again.

Before replacing the battery it is essential to ensure it is the correct type and size. If the replacement battery isn't big enough or has different voltage, it can damage the circuit board in the fob's key. You should also clean any corrosive materials off the chip in the fob before installing the new battery. The right battery type can ensure that the key fob is sealed and protected from moisture. Once the key fob is been reinstalled, it should function normally. You should be able to use the second key even if your car displays a message saying "key is not recognized." It is possible to press the button several times before it responds.
