Citroen Berlingo Key Fob Troubleshooting
Citroen's Berlingo Multispace occupies a utilitarian market in the people-carrier market. Its sliding doors at the rear make it easy to squeeze into bay parking spaces and its sturdy cabin is more smack-proof than the majority of upmarket competitors.
If your key fob was submerged in saltwater or soapy liquid it might not function in the future, even after replacing the battery and changing the program. This is because the internal chip has been damaged by exposure to water.
Water Damage
After rescuing your key fob from whatever puddle, pool or washing machine it was swimming in, get rid of the most water you can by shaking it. Lay it flat with the button side facing up and leave it to drain for a couple of minutes while you wipe the inside using a cloth. This will stop any condensation from causing damage to your electronic chip.
If the dashboard warning light that appears like a car, with an image of a key illuminates on your Mk 2 or Mk 3 Citroen Berlingo then it could be an indication of an immobilizer problem. This is a security function in the vehicle that prevents thieves from using hotwires. If this is the case you'll need to see an Citroen dealer or a certified mechanic to solve the issue.
A constant warning light could indicate that the electric power-assisted steering has a problem. If this is the case then you need to take the car off and check whether the pressure of the oil is not too high and that the temperature is not too high before you restart it. If the issue continues, you will need to see a Citroen dealership or a trained mechanic to fix the problem.
Dead Battery
The most common reason for the key fob that isn't working within your Berlingo is a dead battery for the coin. The button cell battery within the key is simple to replace, but you must make sure that you are using the correct voltage size, type and size of battery. A non-compatible cell can damage the circuit. A dead coin battery could also disable the anti-theft system. This is a security measure that stops the engine from being started without the physical key.
If the key fob is still not responding to the lock button even after replacing the battery it could be due to an issue with the receiver module, which is not communicating with the other modules of your vehicle. This can be diagnosed with an OBDII scan tool.
If the key fob is still not responding, you can try reprogramming. Follow the steps in your owner's manual for this procedure. After it is reprogrammed device should work perfectly.
Fault Diagnosis
The reliability of the Citroen Berlingo is generally praised by its owners. However, like any vehicle there are some issues that arise. One of the most frequent is an inoperable key fob battery. Fortunately, it is simple to diagnose and can be fixed within a few minutes. G28 that could occur could be caused by a worn or damaged button or 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 created in the same way. Some batteries are made of inferior materials, and can cause damage to your remote key fob or other electronic components inside your vehicle. Use only batteries of the same type and voltage as the original when replacing the battery. Also, make sure that the new battery is fitted correctly. 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 point in the form of the shape of a triangle on the dashboard, it's a sign that there is an issue with the electric power-assisted driving system in your vehicle. If the warning light appears when you drive, we recommend that you speak with a certified mechanic at a Citroen Berlingo dealership (incl Multispace).
Radio Interference
Radio interference could be the cause of your key fob not working at all times. This is a common problem caused by devices that operate on the same frequency as your remote control. Certain wireless security devices, such as LED lights that are sold aftermarket, may interfere with RF signal. If you have one of these gadgets at home, consider moving them to a different room to see if this helps.
In addition to devices that utilize the same frequency, there are also environmental factors that can interfere with the car's key fob. For instance, metal objects can interfere with the signal's strength. In addition, rainy weather can cause the antenna of the fob to bend, which can result in an weakened signal. In some instances even if the fob is located close to the vehicle, it may not respond to radio signals.
Check the battery to make sure the health of your key fob. The battery is in good condition and the contacts should not be corroded. A damaged or corroded contact can be the primary reason for a key fob not responding to the vehicle's radio signals. A drained battery can cause the fob to malfunction. If you replace the battery and the issue persists, it's a good indication that the antenna is damaged. A professional locksmith can inspect the key fob and make necessary repairs.
