"A Guide To Citroen C1 Replacement Key In 2023
Citroen Berlingo Key Fob Troubleshooting

Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding doors at the rear allow it to fit into parking bays and its durable cabin is more bashing-proof than most upmarket rival offerings.

If your key fob was exposed to soapy or salt water, it may not function properly again - even after a fresh battery and updating. This is because the internal chip has been damaged by exposure to water.

Water Damage

Shake your key fob to drain as much water as you can. Place it on the ground with the button in the downward position and let it run off for a couple of minutes before wiping the inside using a soft cloth. This will stop any condensation from damaging the electronic chip.

If the warning light on the dashboard that appears like a car and has an engraved key symbol appears on your Mk 2 or Mk 3 Citroen Berlingo then it could be an indication of an immobilizer issue. This is a security device in the vehicle that stops thieves from installing hotwires. If this is the case, then you will need to visit a Citroen dealer or a trained mechanic to fix the issue.

A constant on engine warning light could indicate that the power-assisted steering has a fault. If this is the case then you must stop the vehicle and check the oil pressure and temperature before starting it. If the problem persists then you must visit a Citroen dealership or a certified mechanic to fix the problem.

G28 for the key fob not functioning within your Berlingo is a dead battery for the coin. The button cell inside the key can be easily replaced, but it is important to use the right voltage, size and type of battery. A non-compliant cell could damage the circuit. A dead coin-cell battery could also disable the anti-theft feature. This is a safety feature that prevents the engine from starting without a physical key.

If the key fob still not responding to the lock button even after replacing the battery It could be due to an issue with the receiver module, which is not communicating with the other modules on your vehicle. This can be identified using an OBDII scan tool.

If the key fob still isn't responding, then you may try reprogramming it. To do this, follow the steps in your owner’s manual. Once the device has been reprogrammed device should function perfectly.

Diagnosis of a Fault

The reliability of the Citroen Berlingo is generally highly praised by its owners. As with all vehicles, there are a few issues that can arise. A key fob that is dead is one of the most frequent issues. Fortunately, this is easy to identify and can be fixed in a few minutes. Other problems that can arise include a worn 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 know that not all key fob batteries are created equal. Some batteries are constructed from inferior materials that can damage your remote, or other electronics. Make sure you only use batteries of the same kind and voltage as the original battery. Make sure that the new battery fits correctly. Make sure that the positive (+) side of the battery faces upwards when it is placed in the battery slot.

If you see an indicator light on your dashboard that looks like an exclamation mark, this indicates that the vehicle is detecting an issue with its electric power-assisted steering. If this warning light appears while driving, it's advised that you seek advice from a certified mechanic or Citroen Berlingo (incl Multispace) dealership.

Radio Interference

If your key fob has stopped working at all it could be a result of radio interference. This is a common problem caused by devices that operate on the same frequency as your remote control. For instance, wireless security systems and LED lights can interfere with RF signals. Try moving these devices into an alternative location if you've got them at home.

Environmental factors can also interfere with the key fob on cars and other devices using the same frequency. Metal objects, for example can affect the signal strength. Weather conditions that are rainy can cause the antenna of the key fob to bend, which can result in weaker signals. In some cases even if the fob is near to the car, it may not respond to radio signals.

To ensure that your key fob is functioning properly examine the battery. The battery should be in good working order and the contacts should not be affected by corrosion. A damaged connection is the main reason why the keyfob isn't responding to radio signals coming from vehicles. A depleted battery could cause the fob to malfunction. If you replace the battery and the problem persists, it is likely that the antenna is not functioning properly. A locksmith can inspect the keyfob and make repairs.
