Water Damage

After you have rescued your key fob from whatever puddle, pool or washing machine it was swimming in, get rid 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 wipe down the inside with a soft cloth. This will prevent 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 car key symbol appears to be lit, then it could indicate a fault with the immobilizer. It is a security device in the vehicle to prevent thieves from hotwiring it. If this is the situation you'll need to see a Citroen dealer or a trained mechanic to solve the issue.

If this is so, then you should take the car off and check whether the pressure of the oil is fine and the temperature isn't overly high before you start it. If the issue continues, you'll need to visit a Citroen dealership or a trained mechanic to address the issue.

Dead Battery

The most common cause of the key fob being inoperative on your Berlingo is a dead coin battery. The button cell inside the key can be replaced but it is crucial to use the right size, voltage and type of battery. An uncompatible battery can harm the circuit. A dead battery for a coin-cell could also disable anti-theft. This is a safety measure that prevents the engine from getting started without the physical key.

If the key fob still doesn't respond to the lock button after replacing the battery it could be that the receiver module is faulty and not communicating with other modules in your vehicle. This can be detected using an OBDII scan tool.

If the key fob is not responding, you can try reprogramming it. To do this, follow the guidelines in your owner’s manual. Once it is reprogrammed device should function as expected.


Diagnosis of a Fault

Citroen Berlingo owners are generally pleased with the vehicle's reliability. However, as with all vehicles there are some issues that can arise. One of the most frequent is a dead key fob battery. This is a straightforward issue to determine and can be repaired within a matter minutes. Other problems could be a worn button, water damage on the electronic chip, interference in the signal or a remote system receiver module that is defective.

It is important to remember that not all key fob batteries are in the same way. Some batteries are made of inferior materials and could cause damage to your remote, or other electronics. When replacing the battery, make sure you use a battery that is of the same type and voltage as the original. Also, ensure that the new battery is inserted correctly. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing upwards.

If you notice an alert light on the dashboard of your car that resembles an exclamation mark, it indicates that the vehicle is detecting an issue with its electronic power-assisted steering. If the warning light illuminates during driving, it is advised that you seek advice from a trained mechanic or Citroen Berlingo (incl Multispace) dealership.

Radio Interference

If your key fob stops working suddenly, it could be a result of radio interference. This is a frequent issue caused by devices that operate on the same frequency as your remote control. For instance, wireless security systems, as well as aftermarket LED lights can interfere with radio frequency 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 operate on the same frequency, there are also environmental factors that can affect the signal of a car's key fob. For instance, metal objects could affect the signal's strength. Weather conditions that are rainy can cause the antenna of the fob to bend, leading to weaker signals. In some instances the key fob might not be able to respond to radio signals, even if it is near to the vehicle.

Check the battery to make sure the health of your key fob. It must be in good working order and the contacts must be free of corrosion. A corroded connection is the primary reason the fob's keypad does not respond to radio signals coming from vehicles. A depleted or damaged battery can cause fobs to malfunction. If the problem persists after replacing the battery, the antenna could be defective. A locksmith can inspect the keyfob to make repairs.
