Diagnosis of a Fault
The reliability of the Citroen Berlingo is generally highly praised by its owners. However, as with all vehicles there are some issues that do occur. One of the most frequent is a dead battery on the key fob. Fortunately, it is simple to find and can be replaced within a matter of minutes. Other issues that can occur include a worn button or button, water damage to the electronic chip, signal interference, or a remote keyless system receiver module that has developed an issue.
It is vital to be aware that not all keyfob batteries are the same. Certain batteries are made from inferior materials and may damage your remote key fob as well as other electronic components in your car. When replacing the battery, ensure you make sure that the battery is of the same type and voltage as the original. Also, make sure the new battery is installed correctly. Check that the positive (+) side of the battery is facing upwards when it is placed in the battery slot.
If you see an exclamation point in the form of a triangle on your dashboard, it means that there is an issue with the electric power-assisted driving system in your vehicle.

Radio Interference
If your key fob isn't functioning at all, it could be a 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, like LED lights aftermarket, can interfere with RF signals. If you own any of these devices at home, consider shifting them to a different area to see if this helps.
In addition to devices using the same frequency, there are environmental factors that could affect the signal of a car's key fob. Metal objects, like a car can affect the signal strength. The weather's rain can also cause the antenna of the key fob to bend, which can result in an ineffective signal. In some instances the key fob might not be able to respond to radio signals even though it is within range of the vehicle.
To ensure that your key fob is functioning properly make sure you check the battery. It must be in good working order, and the contacts should be free of corrosion. Contacts that are corroded are the primary reason for the fob's key not responding to the radio signals. A depleted battery could cause a fob to malfunction. If you replace the battery, but the problem persists, it's possible that the antenna is not functioning properly. A locksmith can examine the keyfob to make repairs.
