Citroen Berlingo Key Fob Troubleshooting

If your key fob has been bathed in soapy or salt water, it might not be working again, even after a fresh battery and changing the program. The internal chip may be damaged by exposure to water.
Water Damage
Shake your key fob to get rid of as much water as you can. Lay it on the floor with the button in the downward position and let it dry for a couple of minutes before wiping the inside with a soft cloth. This will stop any condensation from damaging the electronic chip.
If the warning light on your dashboard that looks like a vehicle with the key symbol is on your Mk 2 or Mk 3 Citroen Berlingo then this could be a sign of an immobilizer problem.

Dead Battery
The most frequent cause of the key fob not functioning in your Berlingo is the battery in the coin is dead. The button cell battery within the key is easy to replace, however it is important to ensure that you are using the correct voltage and size battery. A non-compliant cell could damage the circuit.

Troubleshooting
The reliability of the Citroen Berlingo is generally appreciated by its owners. Like all vehicles, problems can happen. A dead key fob is one of the most frequently encountered issues.

Other problems include a worn-out button, water damage to the electronic chip or the signal being distorted, or a remote system receiver module with a fault.
It is important to note that not all key fob batteries are made equal. Some batteries are constructed from inferior materials and could cause damage to your remote as well as other electronic. Make www.g28carkeys.co.uk to use only batteries of the same type and voltage as the original when replacing the battery. Make sure the new battery is properly fitted. Check that the positive (+) side of the battery is facing upwards when it is placed in the slot for the battery.
If you notice a warning light on your car's dashboard that resembles a triangle with an exclamation point, this indicates that your vehicle has identified problems with its electric power-assisted steering. If this warning light illuminates while you are driving, we recommend that you contact a trained mechanic at an Citroen Berlingo dealership (incl Multispace).
Radio Interference
Radio interference could be a cause of your key fob not working at all times. This is a common problem caused by devices that use the same frequency as your remote control. For instance, some wireless security systems as well as aftermarket LED lights can interfere with the RF signals. If you have one of these gadgets at home, you can try moving them into a different space to see if it helps.
Environmental factors can also affect the key fob on cars as well as other devices using the same frequency. Metal objects, like a car could interfere with the strength of the signal. Rainy weather can also make the fob's antenna turn, which results in a weaker signal. In certain situations, the key fob may not be able to respond to radio signals, even if it is near to the vehicle.
To ensure that your key fob's health is good, check the battery. The battery should be in good working order and the contacts shouldn't be damaged by corrosion. A damaged or corroded contact can be the primary reason for the fob's key not responding to the radio signals. A depleted battery could cause the fob to malfunction. If the issue continues to persist after replacing the battery, the antenna may be malfunctioning. A professional locksmith can inspect the key fob and make the required repairs.
