Citroen Berlingo Key Fob Troubleshooting

Citroen's Berlingo Multispace occupies a utilitarian market in the people-carrier market. Its sliding rear door makes it easy to fit into bay parking spaces and its tough cabin can withstand more abuse than most upmarket competitor offerings.

If your key fob has been bathed in soapy or salt water, it might not function properly again - even after a fresh battery and updating. The internal chip may be damaged due to exposure to water.

Water Damage

After getting your key fob back from whatever pool, puddle or washing machine it's been swimming in, clear it of as much water as you can by shaking it. Then lay it with the button side facing up and leave it to drain for a couple of minutes while you wipe the inside using a cloth. This will stop any condensation from causing damage to the electronic chip.

If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which looks like an automobile key symbol illuminates then this could indicate an issue with the immobilizer. This is a security component within the vehicle to deter thieves from hotwiring it. If this is the case then you need to go to an Citroen dealer or a trained mechanic in order to resolve the problem.

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 check that the oil pressure is in good order and that the temperature is not too high prior to restarting it. If the issue continues and you are unable to resolve it, visit a citroen key fob dealership or trained mechanic to resolve the problem.

Dead Battery

The most frequent reason for the key fob being inoperative on your Berlingo is a dead battery for the coin. The button cell inside the key can be replaced, but it is important to use the right size, voltage, and type of battery. A non-compatible cell can damage the circuit. A dead coin battery could also disable the anti-theft system. This is a security measure that prevents the engine being started without a physical key.

If the key fob still isn't responding to the lock button after replacing the battery it could be because the receiver module is faulty and isn't communicating with other modules in your vehicle. This can be confirmed using an OBDII scan tool.

If the key fob isn't responding, you can try reprogramming the key fob. To do this, follow the directions in the owner's manual. After it is reprogrammed device should work perfectly.

Diagnostics of a fault

Citroen Berlingo owners are generally pleased with the reliability of the vehicle. As with all vehicles it is possible for faults to occur. One of the most common is an inoperable key fob battery. It is a simple issue to determine and can be fixed within a matter minutes. Other problems include a worn-out button, water damage to the electronic chip, interference in the signal, or a remote system receiver module that is defective.

It is important to remember that not all key fob batteries are created identical. Some batteries are made from inferior materials that could damage your remote or other electronics. Use only batteries that are the same size and voltage as the original when replacing the battery. Also, make sure the new battery is properly fitted. When inserting the battery into the slot, make sure the positive (+) face of the battery is facing towards the upward direction.

If you see a warning light on the dashboard of your car that appears to be an exclamation mark, this indicates that the vehicle has detected problems with its electric power-assisted steering. If the warning light is illuminated when driving, it is advised to seek help by a trained mechanic or Citroen Berlingo (incl Multispace) dealership.

Radio Interference

Radio interference could be a cause of your key fob not working immediately. This is a typical issue caused by devices that use the same frequency as your remote control. Some wireless security devices, such as LED lights from the aftermarket, could interfere with RF signals. Move these devices to another room if you have them in your home.

Environmental influences can also disrupt the key fob of automobiles in addition to other devices that operate on the same frequency. Metal objects, like a car can affect the signal strength. The weather can also bend the antenna of the fob, resulting in a weaker radio signal. In some instances even if the fob is located close to the vehicle it may not respond to radio signals.

To make sure that your key fob's health is good make sure you check the battery. The battery should be in good working order and the contacts shouldn't be damaged by corrosion. A corroded connection is the main reason the keyfob doesn't respond to radio signals from the vehicle. A drained battery can also cause the fob to malfunction. If you replace the battery and the issue persists, it's a good indication that the antenna is defective. A locksmith can examine the keyfob, and make repairs.
