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 sturdy cabin is more bashing-proof than the most expensive rivals.
However, if your device has been bathed in soapy or salt water, it might not function again, even after a fresh battery and reprogramming. This is because the internal chip has been damaged by exposure to water.
Water Damage
After retrieving your key fob from whatever puddle, pool or washing machine it's been swimming in, clear it of as much water as you can by shaking it. Then lay it with the button side facing up and let it dry for a short time while you wipe the inside down with a clean cloth. This will prevent any condensation from damaging your electronic chip.
If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which looks like an automobile key symbol lights up, it could be an issue with the immobilizer. This is a security feature within the vehicle to deter thieves from stealing it. If this is the case you'll need to see a Citroen dealer or a certified mechanic to solve the issue.
A constant engine warning light could indicate that the steering system with electric power has a problem. If this is the situation, then you should take the car off and check that the oil pressure is not too high and that the temperature isn't overly high before you start it. If the problem persists then you will need to see a Citroen dealership or a trained mechanic in order to resolve the problem.
Dead Battery
The most frequent cause of the key fob not functioning inside your Berlingo is an inactive coin battery. The button cell inside the key can be easily replaced however it is essential to use the right voltage, size, and type of battery. A battery that is not compatible can cause damage to the circuit board. A dead coin battery can also disable the anti-theft system. This is a security function that stops the engine from starting without a 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 defective and is not communicating with other modules in your vehicle. OBDII scanners can identify this issue.
If the key fob still not responding, try reprogramming. Follow the steps in the owner's manual for this procedure. It should work as expected once it is updated.
Diagnosis of a Fault
Citroen Berlingo owners are generally satisfied with the reliability of the car. As with all vehicles there are a few issues that can arise. A dead key fob is among of the most frequently encountered issues. Fortunately, this is easy to determine and can be replaced in a few minutes. Other problems could be a worn button, water damage on the electronic chip, interference in the signal, or a remote system receiver module with a fault.
It is vital to be aware that not all keyfob batteries are same. Some batteries are constructed from inferior materials that could damage your remote as well as other electronic. Make sure to use only batteries of the same kind and voltage as the original when replacing the battery. Make sure that the new battery is properly fitted. Make sure that the positive (+) side of the battery is facing upwards when it is inserted into the slot for the battery.
If you see an indicator light on your dashboard that looks like an exclamation mark on it, this signifies that the vehicle is detecting an issue with its electronic power-assisted steering. If the warning light is illuminated while you are driving and it is not able to be removed, we recommend you seek out a qualified mechanic at a Citroen Berlingo dealer (incl Multispace).
Radio Interference
If your key fob has stopped working at all, it could be a result of radio interference. This is a problem that can be caused by devices using the same frequency as remote controls. Some wireless security systems, for instance LED lights that are sold aftermarket, may interfere with RF signal. If you own any of these devices at home, try moving them to a different room to see if this helps.
Environmental influences can also disrupt the key fob in the car in addition to other devices with the same frequency. Metal objects, like a car can impede the signal strength. Rainy weather may also bend the antenna of the fob, resulting in a weaker radio signal. In certain situations, the key fob may not be able to respond to radio signals even though it is located near the vehicle.
Check the battery to make sure your key fob's health. The battery should be in good shape and the contacts shouldn't be affected by corrosion. A damaged connection is the primary reason the keyfob isn't responding to radio signals coming from the vehicle. A drained battery can also cause the fob to malfunction. If the problem persists after replacing the battery the antenna could be defective. G28 Car Keys will examine the key fob and make the required repairs.
