Citroen Berlingo Key Fob Troubleshooting
Citroen's Berlingo Multispace occupies a utilitarian niche in the people carrier market. Its sliding rear door allows it to be easily inserted into bay parking spaces and its robust cabin is more durable than most upmarket competitor offerings.
If your key fob was submerged in saltwater or soapy liquid the device may not function in the future, even after replacing the battery and the reprogramming. The internal chip can be damaged by exposure to water.
Water Damage
After getting your key fob back from whatever puddle, pool or washing machine it's been swimming in, clear it of the most water you can by shaking it. Then, lay it on the button facing down and allow it to drain for a couple of minutes while you wipe the inside using a towel. This should stop any condensation from causing damage to the electronic chip.
If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which appears like the symbol of a car key, is lit, it could be indicating a fault with the immobilizer. This is a security element inside the vehicle that prevents thieves from stealing it. If this is the case, then you need to go to an Citroen dealer or a trained mechanic to resolve the problem.
A constant warning light could mean that the power-assisted steering is in trouble. 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 too high prior to resuming it. If the problem continues to persist, you will need to visit a Citroen dealer or a qualified mechanic to resolve the issue.
Dead Battery
A dead battery in the coin is the most frequent reason for your key fob not to work in your Berlingo. The button cell inside the key can be replaced, but it is important to select the correct size, voltage and type of battery. A non-compatible battery can damage the circuit board. A dead coin battery could also disable the anti-theft system. This is a security measure that prevents the engine from getting started without the physical key.
If the key fob is 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 in your car. This can be diagnosed with an OBDII scan tool.
If the key fob isn't responding, then you may try reprogramming it. Follow the directions in your owner's manual for this procedure. It should work as expected once it has been reset to its original program.
Diagnosis of a Fault

Citroen Berlingo owners are generally satisfied with the reliability of the car. As with all vehicles problems can happen. A dead key fob is among of the most frequent problems. It is a simple issue to identify and can be repaired in a matter of minutes. Other issues include a worn out button, water damage to the electronic chip, interference in the signal or a remote system receiver module that has a problem.
It is important to keep in mind that not all key fob batteries are created to be the same. Some batteries are made from inferior materials that can damage your remote, or other electronics. When replacing the battery, you should use a battery that is of the same voltage and type as the original. Make sure that the new battery fits correctly. When inserting the battery into the slot, make sure the positive (+) face of the battery is facing upwards.
If you see an exclamation point in the form of a triangle on your dashboard, it is a sign that there is an issue with the electric power-assisted driving system in your vehicle. If this warning light comes on while you are driving and you notice it, we suggest that you speak with a certified mechanic at the Citroen Berlingo dealership (incl Multispace).
