Citroen Berlingo Key Fob Troubleshooting
Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding rear doors allow it to be squeezed into parking bays and its durable cabin is more resistant to crashing than the majority of upmarket competitors.
But if your key fob was bathed in soapy salt water, it may not work again - even after a fresh battery and reprogramming. The internal chip is damaged because of exposure to water.
Water Damage
Shake your key fob to drain as much water as you can. Lay it down with the button down, and let it drain for a few minutes while you wipe down the inside with a soft cloth. This should 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 looks like the car key symbol is lit, it could be indicating an issue with the immobilizer. It is a security device inside the vehicle that prevents thieves from hotwiring it. If this is the case then you must visit an Citroen dealership or a certified mechanic to resolve the issue.
A constant warning light for the engine could indicate that the electric power assisted steering system is failing. If this is the situation then you must stop the vehicle and check the temperature and pressure of the oil before restarting it. If citroen berlingo key continues to persist, you'll need to visit a Citroen dealer or trained mechanic to resolve the problem.
Dead Battery
A dead battery for your coin is the most frequent reason for your key fob to not function in your Berlingo. The button cell battery in the key is easy to replace, however you should ensure that you use the correct voltage size, type and size of battery. A battery that isn't compatible could cause damage to the circuit board. A dead coin-cell battery can also disable anti-theft. This is a safety measure that stops the engine from being 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 that the receiver module has failed and not communicating with other modules in your vehicle. This can be identified using an OBDII scan tool.
If the key fob isn't working, you can try reprogramming the key fob. Follow the steps in your owner's manual to do this. It should work as expected once it has been changed.
Fault Diagnosis
Citroen Berlingo owners are generally satisfied with the reliability of their vehicle. However, like all vehicles there are a few issues that arise. A key fob that is not working is one of the most frequently encountered issues. Fortunately, it is simple to find and is easily replaced within a matter of minutes. Other issues that could arise include a worn-out button or a water damage to the electronic chip, signal interference, or a remote keyless system receiver module that has developed a fault.
It is important to keep in mind that not all key fob batteries are to be the same. Certain batteries are made of inferior materials, which can cause damage to your remote as well as other electronic. When replacing the battery, ensure you make sure the replacement battery is of the same voltage and type as the original. Make sure that the new one is inserted correctly. Check that the positive (+) side of the battery is facing upwards when inserted into battery slot.
If you see an indicator light on your dashboard that resembles an exclamation mark, it means that the car has detected an issue with its electric power-assisted steering. If the warning light appears when you drive, we recommend that you seek out a qualified mechanic at a Citroen Berlingo dealer (incl Multispace).
Radio Interference
If your key fob stops functioning at all it could be the result of radio interference. This is a typical issue caused by devices that use the same frequency as your remote control. Certain wireless security systems, such as LED lights sold on the market, can interfere with RF signals. If you own one of these devices at home, you can try moving them into a different space to see if it helps.
In addition to devices using the same frequency, there are environmental factors that could affect the signal of a car's key fob. For instance, metal objects may influence the strength of the signal. Rainy weather can also alter the antenna of the fob, resulting in a weaker radio signal. In certain situations the key fob might not respond to the radio signals even when it is close to the vehicle.
To make sure that your key fob's health is good examine the battery. It must be in good working order, and the contacts should be free of corrosion. Contacts that are damaged by corrosion are the primary reason for a key fob not responding to the vehicle's radio signals. A depleted battery could cause the fob to malfunction. If you replace the battery, but the problem persists, it is likely that the antenna is not functioning properly. A professional locksmith will inspect the key fob and make the necessary repairs.
