How Much Do Citroen C1 Replacement Key Experts Make? Citroen Berlingo Key Fob Troubleshooting

Citroen's Berlingo Multispace occupies a utilitarian space in the people carrier market. Its sliding rear doors allow it to fit into parking bays, and its robust cabin is more resistant to crashing than many of the more expensive rivals.

But if your key fob was exposed to soapy or salt water, it could not work again - even after a new battery and changing the program. The internal chip can be damaged due to exposure to water.

Water Damage

After retrieving your key fob from the puddle, pool or washing machine it was swimming in, get rid of as much water as you can by shaking it. Then lay it with the button side down and let it dry for a short time while you clean the inside using a towel. This will prevent any condensation from damaging the electronic chip.

If the warning light on your dashboard that looks like a car and has an engraved key symbol is on your Mk 2 or Mk 3 Citroen Berlingo then it could be an indication of an immobilizer issue. This is a security element inside the vehicle that prevents thieves from hotwiring it. If this is the situation, you will have to visit a Citroen dealer or a certified mechanic to solve the issue.

A constant on engine warning light could mean that the steering system with electric power has a problem. If this is the situation it is recommended to stop the vehicle and check the temperature and pressure of the oil before starting it. If the issue continues, you'll have to visit an authorized Citroen dealer or mechanic to address the problem.

Dead Battery

The most common reason for the key fob not working in your Berlingo is a dead coin battery. The button cell battery within the key is simple to replace, but you must ensure that you choose the right voltage and size battery. A non-compliant cell could damage the circuit. A dead coin-cell battery can also disable anti-theft. G28 is a security measure which prevents the engine from being started without an actual key.

If the key fob still isn't responding to the lock button, even after replacing the battery it could be because the receiver module is defective and isn't communicating with other modules in your vehicle. OBDII scanners can identify this issue.

If the key fob isn't responding, you can try reprogramming the key fob. Follow the steps in the owner's manual for this procedure. After the device has been reprogrammed, the device should work perfectly.


Fault Diagnosis

The reliability of the Citroen Berlingo is generally appreciated by its owners. However, like all vehicles there are occasional issues that arise. One of the most common is an inoperable key fob battery. Fortunately, this is easy to determine and can be fixed in a few minutes. Other problems include a worn-out button, water damage on the electronic chip and interference in the signal, or a remote system receiver module that is malfunctioning.

It is important to remember that not all key fob batteries are created identical. Some batteries are made of inferior materials and may damage your remote key fob as well as other electronics in your vehicle. Make sure to use only batteries of the same type and voltage as the original when replacing the battery. Also, ensure that the new battery is inserted correctly. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing upwards.

If you see an indicator light on the dashboard of your car which appears like a triangle with an exclamation mark, it indicates that the vehicle is detecting a problem with its electric power-assisted steering. If the warning light appears when you drive and it is not able to be removed, we recommend you seek out a certified mechanic at the Citroen Berlingo dealer (incl Multispace).

Radio Interference

Radio interference could be the cause that your key fob isn't working immediately. This issue can be caused by devices that operate on the same frequency as a remote control. Certain wireless security systems, such as LED lights that are sold aftermarket, may interfere with RF signals. Move these devices to another room if you have them at home.

In addition to devices using the same frequency, there are environmental factors that can hinder the operation of a key fob. Metal objects, for instance could interfere with the signal strength. Rainy weather can also cause the fob's antenna to bend, leading to an weakened signal. In some cases even if the fob is located close to the car it might not respond to radio signals.

Examine the battery to confirm your key fob's health. The battery must be in good condition and the contacts must not be affected by corrosion. A corroded or damaged connection is the primary reason the keyfob doesn't respond to radio signals coming from the vehicle. A depleted battery may cause fobs to malfunction. If you replace the battery, but the issue persists, it is likely that the antenna is not functioning properly. A professional locksmith can examine the key fob and make necessary repairs.
