Once the contacts are cleaned, you are able to insert the new battery. Be careful not to mix the two types since they differ in voltage, dimensions, and shapes.

Next, you will need to test the voltage of the battery. You can get an accurate reading using a multimeter which is calibrated to the battery's voltage range. If the battery is at an amount that is above or below its threshold, it will need to be replaced. Try getting your car started using an additional key, however it may not be effective in all cases.

If it's still not working, it may be the time to replace your key fob.

Another common reason the most common reason for Citroen remote control c3 not working is signal interference. This can occur when there is a strong electrical field close to the vehicle or from other transmitters on the same frequency. The key fob should start to function again after you are out of the area of interference.

The Citroen C3 key fob could not function because of worn buttons or signal interference issues, receiver module problems as well as a dead 12-volt battery or a malfunctioning chip. You'll have to get it changed to a new program when this happens. This can be accomplished by a trained mechanic or an Citroen dealer. If the issue is severe, you may need to replace it. It's a relatively easy and inexpensive fix. However, you need to act quickly. The longer you wait to fix the issue, the more severe it will be. If the issue doesn't get resolved the issue could be a hazard for the passengers and yourself.

Receiver module issue

If your key fob ceases working, it might be due to the receiver module having developed a fault. Water damage is one of the many reasons. This could happen if you drop your keys or wash them. You can resolve the issue by removing and cleaning the chip using isopropyl alcohol or an electronic cleaner. This will stop the chip from corroding.

You can also reset the receiver module when you disconnect it from the battery and wait 10 seconds. Then, reconnect the battery to the car and repeat the process. If this does not fix the issue, take it to a dealership for replacement.

Interference can also cause your key to stop working. This can be caused by other transmitters that operate on the same frequency as your key fob, or by objects inside your vehicle. If you are unable to fix the issue, you can take your key fob in to an authorized dealer and have it changed to a different frequency.

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 will not recognize the car key and display a message that reads "key not detected". This could be a major issue especially when you attempt to start your car.

Dead 12 volt battery

It is possible that your key fob is damaged if it stops working after a change in batteries. This is most likely to happen if the key fob was dropped or stepped upon, but it can also happen following maintenance on your vehicle which requires the removal and reinstallation of the panels. Wires become exposed when panels are removed. If your fob has been damaged, it may require replacement.

A fob that receives interference from other devices and locations is another possibility. This can cause RF signals to become weak and prevent the car from acknowledging the remote. You can reset the onboard computer if this is the situation, by disconnecting the 12-volt battery for 15 minutes. This will take away any remaining power, allowing the system to reboot.

Before replacing the battery it is important to ensure it's of the correct size and type. If the battery you replace isn't big enough or has a different voltage, it can damage the circuit board inside the fob's key. Also, you should clean any corrosive materials off the chip inside the fob prior to installing a new battery. Using the right type of battery can help ensure that it is properly sealed and protected from moisture. After the key fob has been reinstalled, it will function normally. In the majority of instances, you will be able to use the second key to start your car even in the event that it displays an error message that reads "key not detected."
