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 tough cabin is more durable than many upmarket rivals.
But if your key fob has been bathed in soapy or salt water, it may not function properly again - even after a new battery and reprogramming. The internal chip can be damaged because of exposure to water.

After retrieving your key fob from whatever puddle, pool or washing machine it's been being a part of, rid it of as much water as possible by shaking it. Lay it on its back with the button facing downwards, and let it drain for a few minutes while you clean the inside using a soft cloth. This should stop any condensation from damaging the electronic chip.
If the warning light on your dashboard that looks like a car with an engraved key symbol illuminates on your Mk 2 or Mk 3 Citroen Berlingo then this could be a sign of an immobilizer problem. It is a security device within the vehicle to deter thieves from hotwiring it. If this is the case, you will be required to visit an Citroen dealer or a trained mechanic to solve the issue.
An unending engine warning light could indicate that the electric power-assisted steering has a fault. If this is the case, then you need to stop the car and check whether the pressure of the oil is not too high and that the temperature isn't overly high prior to restarting it. If the issue continues, you will need to visit a Citroen dealer or a certified mechanic to fix the issue.
Dead Battery
A dead battery in the coin is the most frequent reason for your key fob not to function in your Berlingo. The button cell in the key can be replaced but it is crucial to select the correct voltage, size and type of battery. An uncompatible battery could damage the circuit board. A dead coin-cell can also disable the anti-theft feature. This is a safety measure 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 isn't communicating with other modules in your vehicle. An OBDII scanner can diagnose this problem.
If the key fob isn't responding, then you can try reprogramming the key fob. To do this, follow the guidelines in your owner’s manual. Once the device is reprogrammed device should be working perfectly.
Troubleshooting
The reliability of the Citroen Berlingo is generally praised by its owners. However, like any vehicle, there are occasionally faults that can arise. One of the most frequent is an inoperable key fob battery. Fortunately, it is simple to diagnose and can be replaced within a few minutes. Other problems that can arise include a worn-out button or 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 realize that not all keyfob batteries are same. Some batteries are made from inferior materials that can damage your remote or other electronics. When replacing the battery, only use a battery that is of the same type and voltage as the original. Make sure that the new one is properly fitted. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing towards the upward direction.
If you see an exclamation mark in the shape of the shape of a triangle on your dashboard, it means that there is a problem with your vehicle's electric power-assisted driving. If this warning light comes on while you're driving, we recommend that you seek out a qualified mechanic at an Citroen Berlingo dealership (incl Multispace).
Radio Interference
Radio interference could be a cause that your key fob isn't working at all times. This issue could be caused by devices using the same frequency as a remote control. For example, some wireless security systems, as well as aftermarket LED lights can interfere with RF signals. If you have any of these devices at home, consider moving them to another room to see if they help.
Environmental influences can also disrupt the key fob on the car as well as other devices with the same frequency. For instance, metal objects can alter the strength of the signal. Rainy weather can also alter the antenna of the fob, which results in a weaker radio signal. In some cases the key fob might not respond to the radio signals even though it is near to the vehicle.
Examine the battery to confirm the health of your key fob. The battery should be in good shape and the contacts shouldn't be damaged by corrosion. A corroded contact is an important reason for a key fob not responding to the radio signals. A drained battery can also cause the fob to malfunction. If the issue continues to persist after replacing the battery the antenna may be malfunctioning. A locksmith can examine the keyfob and make repairs.
