Fault Diagnosis
The reliability of the Citroen Berlingo is generally loved by its owners. Like all vehicles, there are a few issues that can arise. One of the most common is a dead battery on the key fob. Fortunately, it is simple to identify and is easily replaced in a few minutes. Other issues that can occur 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.

Radio Interference
Radio interference could be the reason of your key fob not functioning at all. This is a common issue caused by devices that use the same frequency as your remote control. Some wireless security systems, for instance LED lights that are sold aftermarket, may interfere with the RF signal. If you own any of these at home, try moving them to a different room to see if this helps.
Environmental factors can also affect the key fob of the car in addition to other devices with the same frequency. For instance, metal objects could alter the strength of the signal. Weather conditions can also bend the antenna of the fob, which results in a weaker radio signal. In some instances, even when the fob's location is close to the car, it may not respond to radio signals.
To make sure that your key fob is in good health, check the battery. It must be in good working order and the contacts must be free of corrosion. A damaged or corroded connection is the primary reason the keyfob doesn't respond to radio signals from the vehicle. A depleted battery can also cause fobs to fail. If the issue is still present after replacing the battery the antenna might be damaged. A locksmith can inspect the keyfob, and make repairs.
