Water Damage

After you have rescued your key fob from whatever pool, puddle or washing machine it's been swimming in, get rid of as much water as possible by shaking it. Then lay it with the button facing down and let it dry for a couple of minutes while you wipe the inside using a cloth. This will stop any condensation from damaging the electronic chip.

If the warning light on your dashboard that looks like a car, with the key symbol is on your Mk 2 or Mk 3 Citroen Berlingo then this could indicate an immobilizer problem. This is a security feature in the vehicle that blocks thieves from using hotwires. If this is the case, you will need to visit a Citroen dealer or a trained mechanic to address the issue.

An unending engine warning light could mean that the steering system with electric power is in trouble.

Dead Battery

A dead coin battery is the most common reason for your key fob to not work in your Berlingo. The button cell in the key can be easily replaced however it is essential 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 precautionary measure that stops the engine from being started without an actual key.

If the key fob isn't responding to the lock button after replacing the battery, it could be that the receiver module is defective and is not communicating with other modules in your vehicle. This can be confirmed using an OBDII scan tool.

If the key fob still not responding, you can try reprogramming. Follow the instructions in your owner's manual for this procedure. After it has been reprogrammed, your device should be working perfectly.


Diagnostics of a fault

The reliability of the Citroen Berlingo is generally praised by its owners. As with all vehicles problems can happen. One of the most frequent is a dead key fob battery. Fortunately, this is easy to determine and can be repaired in a few minutes. Other problems include a worn-out button, water damage to the electronic chip or signal, interference or a remote system receiver module that is defective.

It is important to know that not all keyfob batteries are same. Some batteries are made from inferior materials, which can cause damage to your remote or other electronic components. Make sure you use batteries that are of the same type and voltage as the original battery. Also, ensure the new battery is inserted correctly. Ensure the positive (+) side of the battery is facing upwards when it is inserted into the battery slot.

If you see an exclamation mark in the form of an oval on your dashboard, it is a sign that there is a problem with the vehicle's electric power-assisted driver. If the warning light appears while you're driving and you notice it, we suggest that you speak with a certified mechanic at the 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 using the same frequency as a remote control. Some wireless security systems, such as LED lights that are sold aftermarket, may interfere with the RF signal. If you have any of these at home, consider moving them to a different room to see if they help.

Environmental factors can also interfere with the key fob of the car in addition to other devices that operate on the same frequency. Metal objects, for example could interfere with the signal strength. Weather conditions that are rainy can cause the fob's antenna to bend, leading to an ineffective signal. In some cases the key fob might not respond to radio signals even when it is within range of the vehicle.

To make sure that your key fob is healthy make sure you check the battery. It should be in good shape and the contacts must be free of corrosion. A damaged or corroded connection is the main reason why a keyfob does not respond to radio signals coming from the vehicle. A depleted battery may cause fobs to fail. If the issue continues to persist after replacing the battery the antenna may be malfunctioning. A professional locksmith can inspect the key fob and make the necessary repairs.
