What Citroen C1 Replacement Key Experts Want You To Know? Citroen Berlingo Key Fob Troubleshooting

Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding rear door allows it to be easily inserted into bay parking spaces, and its robust cabin can withstand more abuse than the majority of upmarket competitors.

However, if your device has been bathed in soapy or salt water, it might not be working again, even after a new battery and changing the program. The internal chip can be damaged from exposure to water.

Water Damage


Shake your key fob to drain as much water as you can. Lay it on its back with the button facing downwards and let it drain for a couple of minutes while you wipe down the inside using a soft cloth. This will stop any condensation from damaging your electronic chip.

If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which appears like a car key symbol, illuminates then this could indicate an issue with the immobilizer. This is a security feature within the vehicle to deter thieves from hotwiring it. If this is the case you'll be required to visit an Citroen dealer or a certified mechanic to address the issue.

A constant engine warning light could indicate that the electric power assisted steering system is failing. If this is the situation, then you need to stop the car and make sure that the oil pressure is in good order and that the temperature isn't too high prior to resuming it. If the issue persists, 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 being inoperative within your Berlingo is a dead coin battery. The button cell battery that is in the key is very easy to replace, however you must make sure that you select the correct voltage size, type and size of battery. A cell that is not compatible can cause damage to the circuit. A dead coin battery could also disable the anti-theft system. This is a security feature that prevents the engine from starting without a physical key.

If the key fob still isn't responding to the lock button after replacing the battery it could be because the receiver module is damaged and isn't communicating with other modules in your vehicle. This can be diagnosed with an OBDII scan tool.

If the key fob is still not responding, you can try reprogramming. To do this, follow the directions in the manual for your owner. It should work fine once it has been reprogrammed.

Diagnosis of a Fault

The reliability of the Citroen Berlingo is generally highly praised by its owners. Like all vehicles, it is possible for faults to occur. A key fob that is not working is one of the most frequent problems. It is a simple issue to determine and can be repaired in just a few minutes. Other issues that could occur include a worn-out button, water damage to the electronic chip, signal interference, or a remote keyless system receiver module that has developed a fault.

It is important to keep in mind that not all key fob batteries are made in the same way. Certain batteries are made of inferior materials, which can cause damage to your remote or other electronics. Use only batteries of the same type and voltage as the original when replacing the battery. Make sure that the new battery is inserted correctly. Check that the positive (+) side of the battery faces upwards when inserted into the slot for the battery.

If you notice an exclamation mark in the form of an equilateral triangle on the dashboard, it's a sign that there is a problem with your vehicle's electric power assisted driving. 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

Radio interference could be a cause that your key fob isn't functioning at all. This is a common problem caused by devices that operate on the same frequency as your remote control. For example, some wireless security systems and LED lights can interfere with the RF signals. If you own any of these devices at home, try moving them to another room to see if it helps.

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

Examine the battery to confirm the health of your key fob. The battery must be in good condition and the contacts shouldn't be corroded. A corroded or damaged connection is the primary reason the keyfob doesn't respond to radio signals from the vehicle. A depleted battery could cause the fob to malfunction. If G28 Car Keys persists after replacing the battery, the antenna might be damaged. A locksmith can examine the keyfob to make repairs.
