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 robust cabin is more durable than many of the more expensive competitors.


However, if your device was exposed to soapy or salt water, it may not function properly again - even after a new battery and reprogramming. This is because the internal chip has been damaged by exposure to water.

After rescuing your key fob from whatever pool, puddle or washing machine it's been swimming in, clean it of the most water you can by shaking it. Then, lay it on the button facing down and let it drain for a few minutes while you wipe the inside with a cloth. This will prevent any condensation from damaging the electronic chip.

If the dashboard warning light that looks like a car and has the key symbol is on your Mk 2 or Mk 3 Citroen Berlingo then it could be an indication of an immobilizer problem. This is a security component within the vehicle to deter thieves from stealing it. If this is the case you'll be required to visit a Citroen dealer or a trained mechanic to solve the issue.

A constantly flashing engine warning light could indicate that the electric power assisted steering system is malfunctioning. If this is the case it is recommended to stop the vehicle and check the temperature and pressure of the oil before restarting it. If the problem persists then you will need to see an expert Citroen technician or mechanic to address the issue.

Dead Battery

The most frequent reason for the key fob that isn't working on your Berlingo is a dead battery for the coin. The button cell inside the key can be replaced however it is essential to select the correct size, voltage and type of battery. An uncompatible battery could damage the circuit board. A dead battery for a coin can also disable the anti-theft system. This is a precautionary measure that stops the engine from being started without a physical key.

If the key fob is still not responding to the lock button despite replacing the battery it could be an incompatible receiver module that is not communicating with the other modules on your vehicle. An OBDII scanner can diagnose this problem.

If the key fob still is not responding, you can try reprogramming it. Follow the directions in your owner's manual for this procedure. After it has been reprogrammed device should be working perfectly.

Fault Diagnosis

The reliability of the Citroen Berlingo is generally praised by its owners. However, like any vehicle, there are occasionally faults that can arise. One of the most frequent is a dead battery on the key fob. Fortunately, it is simple to determine and can be repaired within a few minutes. Other issues that could occur are a worn button or button, water damage to the electronic chip, signal interference or a remote keyless system receiver module that has developed an issue.

It is important to realize that not all keyfob battery types are the same. Some batteries are made of inferior materials that can damage your remote as well as other electronic. When replacing the battery, you should use a battery that is of the same voltage and type as the original. Also, ensure that the new battery is fitted correctly. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing upwards.

If you see the warning light on your car's dashboard which appears like an exclamation mark on it, this signifies that the vehicle has discovered a problem with its electric power-assisted steering. If this warning illuminates while driving, it is recommended that you seek assistance by a trained mechanic or Citroen Berlingo (incl Multispace) dealership.

Radio Interference

If your key fob has stopped functioning at all, it could be a result of radio interference. This is a common issue caused by devices that use the same frequency as your remote control. For instance, certain wireless security systems as well as aftermarket LED lights can interfere with radio frequency signals. Move these devices to another room if you have them at home.

Environmental factors can also affect the key fob on cars as well as other devices using the same frequency. Metal objects, for instance, can interfere with the signal strength. The weather can also bend the antenna of the fob, which results in a weaker radio signal. In some cases, even when the fob's location is close to the vehicle it might not respond to radio signals.

Examine the battery to ensure the health of your key fob. It must be in good health, and the contacts should be free of corrosion. Contacts that are damaged by corrosion are an important reason for a key fob not responding to the radio signals. A depleted battery could cause the fob to malfunction. If the issue is still present after replacing the battery the antenna may be faulty. A professional locksmith will inspect the key fob and make the necessary repairs.
