Fault Diagnosis
Citroen Berlingo owners are generally pleased with the vehicle's reliability. As with all vehicles, problems can happen. One of the most common is an inoperable key fob battery.

If you notice a warning light on your car's dashboard that looks like a triangle with an exclamation mark, it means that the car has detected problems with its electric power-assisted steering. If this warning light illuminates while you're driving then we recommend that you seek out a certified mechanic at a Citroen Berlingo dealership (incl Multispace).
Radio Interference
Radio interference could be a cause of your key fob not working suddenly. This is a common issue caused by devices that use the same frequency as your remote control. Some wireless security systems, like LED lights from the aftermarket, could interfere with RF signal. If you own one of these devices at home, consider moving them into a different space to see if they help.
In addition to devices that use 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. The weather can also bend the antenna of the fob, resulting in a weaker radio signal. In some instances even if the key fob is close to the vehicle it may not respond to radio signals.
To make sure that your key fob is healthy and functioning properly, test the battery. It should be in good shape, and the contacts should be free of corrosion. Contacts that are corroded are an important reason for the fob's key not responding to the radio signals. A depleted battery could cause the fob to malfunction. If the issue is still present after replacing the battery the antenna may be malfunctioning. A professional locksmith will inspect the key fob and make the required repairs.
