Citroen Berlingo Key Fob Troubleshooting

Citroen's Berlingo Multispace occupies a utilitarian segment in the people-carrier market. Its sliding doors at the rear make it easy to squeeze into parking bays, and its sturdy cabin is more resistant to crashing than many of the more expensive rivals.

If your key fob was submerged in saltwater or soapy waters the device may not function again, even after a new battery and the reprogramming. The internal chip is damaged because of exposure to water.

Water Damage

After getting your key fob back from whatever pool, puddle or washing machine it was being a part of, rid it of as much water as possible by shaking it. Then lay it with the button side down and leave it to drain for a couple of minutes while you wipe the inside down with a cloth. This should prevent any condensation from causing damage to the electronic chip.

If the warning light on your dashboard that looks like a car, with the key symbol illuminates on your Mk 2 or Mk 3 Citroen Berlingo then this could indicate an immobilizer malfunction. This is a security feature inside the vehicle that prevents thieves from using hotwires. If this is the case then you should see a Citroen dealer or a trained mechanic to fix the issue.

An unending engine warning light could indicate that the electric power-assisted steering is not working properly. If this is the case then you must stop the car and ensure whether the pressure of the oil is ok and that the temperature isn't too high before you restart it. If the issue continues then you should visit a citroen c1 replacement key dealer or a certified mechanic to fix the issue.

Dead Battery

A dead battery for your coin is the most frequent reason for your key fob not to work in your Berlingo. The button cell in the key can be easily replaced however it is essential to select the correct voltage, size, and type of battery. A battery that is not compatible can cause damage to the circuit board. A dead coin battery could also disable the anti-theft system. This is a measure of safety which prevents the engine from being started without the physical key.

If the key fob still doesn't respond to the lock button after replacing the battery it could be that the receiver module is damaged and not communicating with other modules in your vehicle. An OBDII scanner can diagnose the issue.

If the key fob still not responding, try reprogramming it. To do this, follow the instructions in your owner’s manual. Once it has been reprogrammed, your device should work perfectly.

Diagnosis of a Fault

Citroen Berlingo owners are generally pleased with the vehicle's reliability. Like all vehicles, it is possible for faults to occur. A key fob that is dead is one of the most common problems. Fortunately, it is simple to identify and is easily replaced in a few minutes. Other issues that could occur include a worn-out button or button, water damage to the electronic chip, signal interference, or a remote keyless system receiver module that has developed a fault.

It is vital to be aware that not all keyfob battery types are the same. Some batteries are made from inferior materials that could damage your remote or other electronics. Make sure you use batteries that are of the same type and voltage as the original battery. Make sure that the new one is inserted correctly. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing upwards.

If you notice an alert light on your car's dashboard that appears to be a triangle with an exclamation mark, it signifies that the vehicle has discovered an issue with its electronic power-assisted steering. If the warning light is illuminated while you're driving then we recommend that you contact a trained mechanic at the Citroen Berlingo dealer (incl Multispace).

Radio Interference

If your key fob stops working all of a sudden it could be a result of radio interference. This issue can be caused by devices using the same frequency as a remote control. For example, some wireless security systems as well as aftermarket LED lights can interfere with radio signals. If you have any of these at home, consider shifting them to a different area to see if they help.

In addition to devices using the same frequency, there are environmental factors that could interfere with a car's key fob. For instance, metal objects can influence the strength of the signal. Rainy weather may also bend the antenna of the fob, which results in a weaker radio signal. In some cases even if the fob's location is close to the vehicle it may not respond to radio signals.

Check the battery to ensure your key fob's health. The battery should be in good working order and the contacts must not be affected by corrosion. A damaged or corroded contact can be one of the main reasons for the fob's key not responding to radio signals. A depleted or damaged battery can cause a fob to malfunction. If the issue persists after replacing the battery the antenna might be damaged. A professional locksmith can inspect the key fob and make the necessary repairs.
