Citroen Berlingo Key Fob Troubleshooting
Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding doors at the rear allow it to fit into parking bays and its robust cabin is more resistant to crashing than many of the more expensive rivals.
If your key fob was submerged in saltwater or soapy liquid It may not work in the future, even after replacing the battery and the reprogramming. This is because the internal chip has been damaged by exposure to water.
Water Damage
After you have rescued your key fob from whatever pool, puddle or washing machine it was swimming in, get rid of the most water you can by shaking it. Lay it on its back with the button facing downwards, and let it drain for a couple of minutes while you clean the inside using a soft cloth. This will stop any condensation from damaging your electronic chip.
If the dashboard warning light that looks like a vehicle with an engraved key symbol is on your Mk 2 or Mk 3 Citroen Berlingo then this could indicate an immobilizer fault. This is a security device in the vehicle to prevent thieves from using hotwires. If this is the situation you'll need to see an Citroen dealer or a certified mechanic to solve the issue.
A constant on engine warning light could indicate that the power-assisted steering is not working properly. If this is the case it is recommended to stop the vehicle and examine the oil pressure and temperature before restarting it. If the issue continues, you'll have to visit an authorized Citroen dealer or mechanic to address the issue.
Dead Battery
The most frequent cause of the key fob that isn't working inside your Berlingo is a dead coin battery. 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 cell can damage the circuit. A dead coin-cell can also disable anti-theft. This is a safety measure that prevents the engine from getting started without a physical key.
If the key fob still doesn't respond to the lock button even after replacing the battery it could be because the receiver module is defective and is not communicating with other modules in your vehicle. OBDII scanners can identify this issue.
If the key fob isn't working, you could try reprogramming it. To do this, follow the directions in the manual for your owner. It should work once it has been changed.
Troubleshooting
The reliability of the Citroen Berlingo is generally highly praised by its owners. However, like citroen key maintenance , there are occasionally faults that arise. A key fob that is dead is one of the most frequent issues. It is a simple issue to diagnose and can easily be repaired in just a few minutes. Other problems could be a worn button, water damage to the electronic chip or signal, interference or a remote system receiver module that is malfunctioning.
It is important to keep in mind that not all key fob batteries are to be the same. Some batteries are made from inferior materials and could cause damage to your remote, or other electronics. When replacing the battery, make sure you make sure the replacement battery is of the same type and voltage as the original. Make sure the new battery fits properly. When inserting the battery into the slot, make sure the positive (+) face of the battery is facing upwards.
If you see an exclamation mark in the shape of a triangle on your dashboard, it is a sign that there is a problem with the electric power-assisted driving system in your vehicle. If this warning illuminates during driving, it is advised that you seek advice by a trained mechanic or Citroen Berlingo (incl Multispace) dealership.
Radio Interference
If your key fob stops functioning at all it could be the result of radio interference. This issue can be caused by devices using the same frequency as remote controls. For example, some wireless security systems and aftermarket LED lights can interfere with RF signals. Consider moving these devices to an alternative location if you've got them at home.
Environmental influences can also disrupt the key fob in automobiles, in addition to devices using the same frequency. Metal objects, for example could interfere with the strength of the signal. Rainy weather may also bend the antenna of the fob, which results in a weaker radio signal. In some cases, even when the fob's location is close to the vehicle it may not respond to radio signals.
Check the battery to ensure the health of your key fob. The battery should be in good working order and the contacts must not be affected by corrosion. A damaged or corroded contact can be a major cause of a key fob that is not responding to radio signals. A depleted battery could cause the fob to malfunction. If the issue is still present after replacing the battery the antenna may be malfunctioning. A professional locksmith can examine the key fob and make necessary repairs.
