Citroen C1 Replacement Key Tips From The Best In The Industry
Citroen Berlingo Key Fob Troubleshooting

Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding rear doors allow it to fit into bay parking spaces and its sturdy cabin is more robust than the majority of upmarket competitors.

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

Water Damage

Shake the key fob of yours to take out as much water as you can. Then lay it with the button side down and let it dry for a few minutes while you wipe the inside down using a cloth. This will prevent any condensation from damaging the electronic chip.

If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which looks like an automobile key symbol appears to be lit, then it could indicate a fault with the immobilizer. This is a security device in the vehicle to prevent thieves from using hotwires. If this is the situation you'll have to visit a Citroen dealer or a trained mechanic to resolve the problem.

An unending engine warning light could indicate that the electric power-assisted steering has a fault. If this is the case then you should take the car off and check that the oil pressure is fine and the temperature isn't overly high prior to resuming it. If the issue continues, you will need to visit a Citroen dealership or a certified mechanic to fix the issue.

Dead Battery

The most common reason for the key fob not working within your Berlingo is an inactive coin battery. The button cell in the key can be easily replaced but it is crucial to select the correct size, voltage and type of battery. A cell that is not compatible can cause damage to the circuit. A dead coin battery may also disable the anti-theft system. This is a security feature that stops the engine from being started without a physical key.

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

If the key fob isn't responding, you could try reprogramming it. To do this, follow the guidelines in the owner's manual. It should work fine once it has been changed.

Diagnosis of a Fault

The reliability of the Citroen Berlingo is generally highly praised by its owners. However, as with all vehicles there are a few issues that arise. One of the most frequent is an inoperable key fob battery. Fortunately, this is easy to diagnose and can be replaced in a few minutes. Other issues that can occur are 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 keyfob batteries will be the same. Certain batteries are made from inferior materials and can damage your remote key fob as well as other electronic components in your car. When replacing the battery, you should make sure you use a battery of the same type and voltage as the original. Make sure the new battery fits properly. Check that the positive (+) side of the battery is facing upwards when it is inserted into the battery slot.


If you see an exclamation point in the shape of an oval on your dashboard, it indicates that there is an issue with your vehicle's electric power-assisted driving. If G28 is illuminated while you are driving and it is not able to be removed, we recommend you contact a trained mechanic at the Citroen Berlingo dealership (incl Multispace).

Radio Interference

Radio interference could be the reason that your key fob isn't working suddenly. This is a problem that could be caused by devices that use the same frequency as remote controls. Certain wireless security systems, like LED lights sold on the market, can interfere with the RF signal. If you have any of these devices at home, consider moving them to another room to see if it helps.

In addition to devices that utilize the same frequency, there are environmental factors that can hinder the operation of a key fob. Metal objects, for instance can impede the strength of the signal. The weather's rain can also make the fob's antenna bend, leading to weaker signals. In certain situations, the key fob may not respond to radio signals, even if it is within range of the vehicle.

Examine the battery to ensure your key fob's health. The battery should be in good shape and the contacts shouldn't be damaged by corrosion. A corroded connection is the main reason the keyfob isn't responding to radio signals from the vehicle. A drained battery can cause the fob to malfunction. If you replace the battery and the issue persists, it's a good indication that the antenna is damaged. A locksmith can inspect the keyfob and fix it.
