Citroen Berlingo Key Fob Troubleshooting

Citroen's Berlingo Multispace occupies a utilitarian segment in the people-carrier market. Its sliding doors at the rear make it easy to squeeze into bay parking spaces and its robust cabin is more smack-proof than most upmarket rival offerings.

But if your key fob has been bathed in soapy or salt water, it might not work again - even after a fresh battery and reprogramming. The internal chip has been damaged because of exposure to water.

Water Damage

After getting your key fob back from the puddle, pool or washing machine it was swimming in, get rid of as much water as possible by shaking it. Then, lay it on the button side down and let it drain for a few minutes as you wipe the inside using a towel. This will prevent any condensation from damaging the electronic chip.

If the dashboard warning light that looks like a car with a key symbol in it is on your Mk 2 or Mk 3 Citroen Berlingo then it could be an indication of an immobilizer issue. This is a security feature in the vehicle that stops thieves from hotwiring. If this is the case, you will need to visit a Citroen dealer or a certified mechanic to resolve the problem.

A constant on engine warning light could indicate that the electric power-assisted steering is in trouble. If this is the situation you need to stop the vehicle and check the oil pressure and temperature before starting it. If the problem persists then you should visit a citroen c5 key fob dealer or a qualified mechanic to resolve the issue.

Dead Battery

The most frequent reason for the key fob not working in your Berlingo is a dead battery for the coin. The button cell inside the key can be replaced however it is essential to select the correct voltage, size, and type of battery. A cell that is not compatible can cause damage to the circuit. A dead coin battery can also disable the anti-theft system. This is a safety feature that stops the engine from being started without the physical key.

If the key fob still does not respond to the lock button even after replacing the battery it could be that the receiver module is faulty and is not communicating with other modules in your vehicle. OBDII scanners can identify this problem.

If the key fob still not responding, try reprogramming it. To do this, follow the steps in the owner's manual. After the device is reprogrammed device should function as expected.

Diagnosis of a Fault

Citroen Berlingo owners are generally pleased with the vehicle's reliability. As with all vehicles, there are a few issues that can arise. One of the most frequent is the battery for the key fob that is dead. Fortunately, this is easy to identify and can be repaired in a few minutes. Other issues that could occur include a worn button or a water damage to the electronic chip, signal interference or a remote keyless system receiver module that has developed an issue.

It is crucial to understand that not all keyfob batteries are same. Some batteries are made of inferior materials and may damage the remote key fob, or other electronic components inside your vehicle. Use only batteries that are of the same type and voltage as the original battery. Make sure that the new battery is inserted correctly. When inserting the battery into the slot, make sure the positive (+) face of the battery is facing towards the upward direction.

If you see an exclamation mark in the shape of a triangle on your dashboard, it means that there is an issue with your vehicle's electric power-assisted driving. If the warning light is illuminated when you drive, we recommend that you contact a trained mechanic at an citroen car key cover Berlingo dealer (incl Multispace).

Radio Interference

Radio interference could be the reason that your key fob isn't working at all times. This issue can be caused by devices operating on the same frequency as remote controls. Some wireless security devices, such as LED lights aftermarket, can interfere with the RF signal. If you have one of these devices at home, try moving them to another room to see if this helps.

Environmental influences can also disrupt the key fob on automobiles and other devices with the same frequency. Metal objects, for example could interfere with the signal strength. The weather can also bend the antenna of the fob, resulting in a weaker radio signal. In some cases, even when the fob's location is close to the car, it may not respond to radio signals.

To ensure that your key fob is functioning properly examine the battery. The battery should be in good working order and the contacts must not be corroded. A damaged or corroded connection is the main reason why a keyfob does not respond to radio signals coming from the vehicle. A depleted or damaged battery can cause fobs to fail. If you replace the battery but the issue persists, it's possible that the antenna is damaged. A locksmith can look over the keyfob, and make repairs.
