Citroen Berlingo Key Fob Troubleshooting
Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding rear door makes it easy to fit into bay parking spaces, and its tough cabin is more durable than many of the more expensive competitors.
If your key fob was submerged in soapy water or saltwater it might not function in the future, even after replacing the battery and programming. The internal chip has been damaged because of exposure to water.
Water Damage
Shake your key fob to drain as much water as you can. Then, lay citroen c4 car keys on the button side down and allow it to drain for a couple of minutes while you wipe the inside down using a cloth. This should stop any condensation from damaging 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, appears to be lit, then it could indicate a fault with the immobilizer. This is a security device in the vehicle that prevents thieves from wiring hotspots. If this is the situation you'll need to visit a Citroen dealer or a trained mechanic to solve the issue.
An unending engine warning light could indicate that the steering system with electric power has a fault. If this is the situation, then you should stop the car and make sure whether the pressure of the oil is ok and that 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 fix the issue.
Dead Battery
A dead battery in the coin is the most common reason for your key fob not to work in your Berlingo. The button cell battery inside the key is very simple to replace, however you should ensure that you are using the correct voltage and size battery. A battery that isn't compatible could cause damage to the circuit board. A dead coin-cell battery could also disable the anti-theft feature. This is a security function that prevents the engine from being started without the physical key.
If the key fob still not responding to the lock button after replacing the battery, it could be an unreliable receiver module that isn't communicating with other modules in your car. A scanner for OBDII can detect the issue.
If the key fob still isn't working, you could try reprogramming it. Follow the directions in your owner's manual to do this. It should work as expected once it is changed.
Fault Diagnosis
Citroen Berlingo owners are generally happy with the reliability of the car. Like all vehicles, problems can happen. A dead key fob is among of the most frequent issues. Fortunately, this is easy to identify and can be repaired within a few minutes. Other problems that can arise include a worn-out button, water damage to the electronic chip, signal interference, or a remote keyless system receiver module that has developed a fault.
It is important to remember that not all key fob batteries are identical. Some batteries are constructed from inferior materials, which can cause damage to your remote, or other electronics. When replacing the battery, ensure you make sure the replacement battery is of the same type and voltage as the original. Also, make sure the new battery is fitted correctly. Check that the positive (+) side of the battery is facing upwards when it is inserted into the slot for the battery.
If you see the warning light on your car's dashboard that looks like an exclamation mark on it, this means that the car is detecting problems with its electric power-assisted steering. If this warning light comes on while you're driving then we recommend that you seek out a certified mechanic at the Citroen Berlingo dealer (incl Multispace).
Radio Interference
If your key fob is not working at all it could be the result of radio interference. This is a frequent issue caused by devices that use the same frequency as your remote control. For example, some wireless security systems, as well as aftermarket LED lights can interfere with RF signals. If you own one of these devices at home, try moving them into a different space to see if they help.
Environmental factors can also affect the key fob of a car, in addition to devices that operate on the same frequency. Metal objects, for instance can impede the signal strength. In addition, rainy weather can cause the antenna of the key fob to bend, which can result in an weakened signal. In some instances even if the fob's location is close to the vehicle it may not respond to radio signals.
To ensure that your key fob is healthy, check the battery. The battery is in good condition and the contacts should not be damaged by corrosion. Contacts that are corroded are the primary reason for key fobs not responding to radio signals. A depleted battery may cause the fob to malfunction. If you replace the battery and the issue persists, it is likely that the antenna is damaged. A locksmith can look over the keyfob to make repairs.
