Citroen Berlingo Key Fob Troubleshooting

Citroen's Berlingo Multispace occupies a utilitarian market in the people-carrier market. Its sliding rear door allows it to be easily inserted into bay parking spaces and its durable cabin can withstand more abuse than many upmarket rivals.

If your key fob was submerged in saltwater or soapy waters, it may not work in the future, even after replacing the battery and the reprogramming. This is because the internal chip has been damaged due to exposure to water.

Water Damage

After rescuing your key fob from whatever puddle, pool or washing machine it was swimming in, get rid of as much water as you can by shaking it. Lay it down with the button down and let it run off for a few minutes before wiping the inside with a soft cloth. This will stop any condensation from causing damage to the electronic chip.

If citroen car keys warning light that appears like a car, with a key symbol in it illuminates on your Mk 2 or Mk 3 Citroen Berlingo then this could indicate an immobilizer fault. This is a security device in the vehicle that blocks thieves from hotwiring. If this is the situation, you will need to see an Citroen dealer or a certified mechanic to address the issue.

A constant warning light for the engine may indicate that the electric power assisted steering is malfunctioning. If this is the situation, then you must stop the car and check whether the pressure of the oil is ok and that the temperature isn't too high prior to resuming it. If the issue continues, you'll need to consult a Citroen dealership or a trained mechanic to resolve the issue.

Dead Battery

A dead battery in the coin is the most common reason for your key fob to not work 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 non-compliant cell could damage the circuit. A dead coin-cell can also disable anti-theft. This is a security measure that prevents the engine from starting without the physical key.

If the key fob still does not respond to the lock button after replacing the battery it could be because the receiver module is faulty and is not communicating with other modules in your vehicle. A scanner for OBDII can detect this issue.

If the key fob still isn't working, you may try reprogramming it. Follow the directions in your owner's manual for this procedure. It should work fine once it has been reprogrammed.

Diagnosis of a Fault

The reliability of the Citroen Berlingo is generally praised by its owners. Like all vehicles, faults can occur. A key fob that is not working is one of the most common problems. Fortunately, it is simple to determine and is easily replaced in a few minutes. Other issues that can occur are a worn 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 vital to be aware that not all keyfob battery types are the same. Certain batteries are made from inferior materials and may damage your remote key fob as well as other electronic components in your vehicle. When replacing the battery, you should use a battery that is of the same type and voltage as the original. Make sure the new battery fits correctly. Make sure that the positive (+) side of the battery faces upwards when inserted into the slot for the battery.

If you notice an indicator light on your dashboard which appears like an exclamation point, this indicates that your vehicle has identified problems with its electric power-assisted steering. If this warning light illuminates when you drive and it is not able to be removed, we recommend you contact a trained mechanic at an Citroen Berlingo dealership (incl Multispace).

Radio Interference

If your key fob has stopped working at all, it could be a result of radio interference. This is a problem that can be caused by devices that use the same frequency as remote controls. Certain wireless security systems, such as LED lights sold on the market, can interfere with the RF signal. Try moving these devices to another area if you have them in your home.

Environmental elements can also impact the key fob on the car, in addition to devices with the same frequency. Metal objects, for instance can affect the strength of the signal. Weather conditions can also bend the antenna of the fob, resulting in a weaker radio signal. In some instances, even when the fob is near to the vehicle it might not respond to radio signals.

To ensure that your key fob is healthy examine the battery. It should be in good condition, and the contacts should be free of corrosion. A damaged or corroded contact can be a major cause of a key fob not responding to the vehicle's radio signals. A drained battery can also cause the fob to malfunction. If the issue is still present after replacing the battery, the antenna could be defective. Locksmiths can check the keyfob and fix it.
