Citroen Berlingo Key Fob Troubleshooting
Citroen's Berlingo Multispace occupies a utilitarian segment in the people-carrier market. Its sliding rear door makes it easy to fit into parking bays, and its robust cabin is more durable than the majority of upmarket competitors.
But if your key fob has bathed in soapy or salt water, it might not function properly again - even after a fresh battery and updating. This is because the internal chip has been damaged due to exposure to water.
Water Damage
Shake your key fob to drain as much water as you can. Lay it flat with the button facing down and leave it to drain for a few minutes as you clean the inside using a cloth. This will prevent any condensation from causing damage to the electronic chip.
If the dashboard warning light that appears like a car and has a key symbol in it illuminates on your Mk 2 or Mk 3 Citroen Berlingo then it could be an indication of an immobilizer issue. This is a security feature inside the vehicle that prevents thieves from stealing it. If this is the case you'll need to visit a Citroen dealer or a trained mechanic to address the issue.
An unending engine warning light could mean that the electric power-assisted steering has a problem. If this is the case then you should stop the car and make sure that the pressure in the oil is ok and that the temperature isn't too high before you start it. If the issue continues, you'll have to visit a Citroen dealer or trained mechanic in order to resolve the problem.
Dead Battery
The most common cause of the key fob that isn't working on your Berlingo is the battery in the coin is dead. The button cell battery in the key is very simple to replace, however you should ensure that you use the correct voltage, size and type of battery. A cell that is not compatible can cause damage to the circuit. A dead coin-cell can also disable anti-theft. This is a security measure that stops the engine from being started without the physical key.
If the key fob isn't responding to the lock button after replacing the battery, it could be that the receiver module has failed and isn't communicating with other modules in your vehicle. An OBDII scanner can diagnose this issue.
If the key fob still isn't working, you could try reprogramming it. To do this, follow the directions in the manual for your owner. It should work as expected once it is reprogrammed.
Troubleshooting
The reliability of the Citroen Berlingo is generally praised by its owners. Like all vehicles, it is possible for faults to occur. One of the most common is the battery for the key fob that is dead. Fortunately, it is simple to find and can be 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 a fault.
It is important to know that not all keyfob batteries are same. Some batteries are made of inferior materials that can damage your remote or other electronic components. Use only batteries that are of the same type and voltage as the original when replacing the battery. Also, ensure that the new battery is installed correctly. Ensure the positive (+) side of the battery faces upwards when inserted into the battery slot.
If you see an exclamation mark in the shape of an equilateral triangle on your dashboard, it means that there is an issue with the electric power-assisted driving system in your vehicle. If citroen ds3 key illuminates while you're driving, we recommend that you contact a trained mechanic at an Citroen Berlingo dealer (incl Multispace).
Radio Interference
Radio interference could be the cause that your key fob isn't working suddenly. This is a problem that could be caused by devices that operate on the same frequency as remote controls. For instance, wireless security systems and aftermarket LED lights can interfere with radio frequency signals. If you own one of these devices at home, you can try moving them to a different 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. For instance, metal objects could alter the strength of the signal. Rainy weather can also alter the antenna of the fob, resulting in a weaker radio signal. In certain situations, the key fob may not respond to the radio signals even if it is near to the vehicle.
Check the battery to make sure your key fob's health. The battery should be in good working order and the contacts shouldn't be corroded. A corroded contact is the primary reason for key fobs not responding to radio signals. A depleted or damaged battery can cause a fob to malfunction. If you replace the battery but the problem persists, it is likely that the antenna is not functioning properly. A professional locksmith will inspect the key fob and make the necessary repairs.
