Citroen Berlingo Key Fob Troubleshooting
Citroen's Berlingo Multispace occupies a utilitarian niche in the people carrier market. Its sliding rear door makes it easy to fit into bay parking spaces, and its robust cabin can withstand more abuse than many of the more expensive competitors.
But if your key fob has been bathed in soapy or salt water, it may not function properly again - even after a new battery and updating. The internal chip can be damaged from exposure to water.
Water Damage
Shake your key fob to remove as much water as you can. Lay it down with the button in the downward position and let it dry for a couple of minutes while you wipe down the inside with a soft cloth. This should prevent any condensation from causing damage to the electronic chip.
If the dashboard warning light that looks like a car, with the key symbol appears on your Mk 2 or Mk 3 Citroen Berlingo then this could be a sign of an immobilizer issue. This is a security feature inside the vehicle that prevents thieves from hotwiring. If this is the situation, you will have to visit an Citroen dealer or a trained mechanic to solve the issue.
A constant warning light could indicate that the steering system with electric power is in trouble. If this is so, then you need to stop the car and ensure that the oil pressure is not too high and that the temperature isn't too high before you restart it. If the issue continues, you'll have to visit an authorized Citroen dealer or mechanic to address the issue.
Dead Battery
A dead battery for your coin is the most common reason for your key fob to not function in your Berlingo. The button cell in the key can be replaced easily however, it is essential to use the right voltage, size, and type of battery. A battery that isn't compatible could cause damage to the circuit board. A dead battery for a coin can also disable the anti-theft system. This is a security function that stops the engine from starting without a physical key.
If the key fob still not responding to the lock button despite replacing the battery it could be an incompatible receiver module that isn't communicating with other modules in your car. This can be detected using an OBDII scan tool.
If the key fob still isn't responding, you could try reprogramming it. To do this, follow the directions in your owner’s manual. It should work fine once it is reprogrammed.
Diagnostics of a fault
Citroen Berlingo owners are generally happy with the reliability of the car. As with all vehicles there are a few issues that can arise. One of the most frequent is a dead battery on the key fob. Fortunately, it is simple to identify and can be fixed in a few minutes. Other issues that could occur could be caused by a worn or damaged button or a water damage to an electronic chip, signal interference, or a remote keyless system receiver module that has developed an issue.
It is important to remember that not all key fob batteries are created equal. Some batteries are made of inferior materials, and can cause damage to the remote key fob, or other electronic components in your vehicle. When replacing the battery, ensure you make sure the replacement battery is of the same voltage and type as the original. Also, make sure that the new battery is inserted correctly. Make sure that the positive (+) side of the battery is facing upwards when it is inserted into the slot for the battery.
If you notice an alert light on your car's dashboard that appears to be an exclamation mark, it means that the car is detecting problems with its electric power-assisted steering. If this warning light comes on when you drive then we recommend that you speak with a certified mechanic at an Citroen Berlingo dealer (incl Multispace).
Radio Interference
Radio interference could be the reason of your key fob not working suddenly. citroen car keys is a typical issue caused by devices that operate on the same frequency as your remote control. For instance, wireless security systems as well as aftermarket LED lights can interfere with radio signals. Try moving these devices to another room if you have them at home.
Environmental influences can also disrupt the key fob on the car as well as other devices that operate on the same frequency. Metal objects, for example can affect the signal strength. The weather can also bend the antenna of the fob, which results in a weaker radio signal. In some instances the key fob might not respond to radio signals, even if it is located near the vehicle.
Examine the battery to confirm your key fob's health. The battery should be in good working order and the contacts should not be corroded. A corroded connection is the main reason why a keyfob does not respond to radio signals coming from a vehicle. A depleted battery may cause a fob to malfunction. If the issue is still present after replacing the battery, the antenna could be defective. A professional locksmith will inspect the key fob and make any necessary repairs.
