After the contacts have been cleaned, you can then install the new battery. Be careful not to mix up the two kinds as they differ in voltage, dimensions and shapes.

The next step is to check the voltage of the battery. A multimeter calibrated to the battery's voltage range will give you a reliable reading. If the battery's current value is in the middle or above the threshold, it needs to be replaced. You can also start your car with a spare key. However, this may not always work.

Once you do, dry out the circuit board as much as you can using an abrasive swab of cotton that's been soaked in isopropyl alcohol or electronic cleaner. If it doesn't work it could be time for a new key fob.

Another common cause the most common reason for citroen c5 key fob remote control c3 not working is signal interference. It can happen when there is an intense electrical field near the car, or from other transmitters on the same frequency. The key fob will begin working once you have left the zone of interference.

The Citroen C3 key fob can stop working because of worn buttons signals, signal interference issues receiver module problems or a dead 12-volt battery or a defective chip. If this happens, you'll require it to be reprogrammed by an expert. This can be accomplished by a qualified mechanic or at a citroen ds3 replacement key cost dealership.

Issue with the Receiver module

If your key fob ceases working, it might be due to the receiver module having developed an issue. Water damage is among the numerous causes. It can happen when you lose your keys, or wash them. You can attempt to fix the issue by taking off and cleaning the chip with isopropyl alcohol, or electronic cleaner. This will keep the chip from getting corroded.

You can also reset the receiver module if you disconnect it from the battery for 10 seconds. You can then reconnect the battery and repeat the process. If this fails to fix the issue, you can visit a dealership to have it replaced.

Another reason why your key could not work is due to interference. This can be caused either by other transmitters that operate on the same frequency or by objects inside your vehicle. If you're unable to solve the issue, take your key fob to a 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 in order, the receiver module won't recognize the key and display a key not detected message. This could be a very frustrating issue, especially when trying to start your car.

Dead 12 volt battery

If your key fob ceases working after a battery change, it may be damaged. This is particularly true if the key fob was dropped or stepped on, however it could also occur following repair on your vehicle which requires the removal and reinstallation of the panels. When these panels are removed, wires are exposed. If your fob is damaged, you may need to replace it completely.

Another possibility is that the fob is receiving interference from other devices or places. This can cause RF signals to become weak and prevent the car from acknowledging the remote. It is possible to reset the onboard computer in this situation, by disconnecting the 12-volt battery for 15 minutes. This will erase any remaining electricity and allow the system to start from scratch.

Before replacing the battery, it's important to make sure it's of the correct size and type. The circuit board on the key fob can be damaged in the event that the replacement battery is too large or has an incompatible voltage. Before installing a new battery, you should clean the chip of the fob in order to eliminate any contaminants that could cause corrosion. Using the correct type of battery will ensure that it is sealed and shielded from moisture. Once the key fob has been reinstalled, it will function normally. You can usually use the second key even if your car displays a message that reads "key not found." It is possible to press the button a few times before it responds.
