Citroen Berlingo Key Fob Troubleshooting
Citroen Berlingo Multispace fills a niche in the market for people carriers. citroen key shell sliding doors at the rear make it easy to squeeze into parking bays and its robust cabin is more smack-proof than the majority of upmarket competitors.
But if your key fob was bathed in soapy salt water, it could not function properly again - even after a fresh battery and changing the program. The internal chip is damaged because of exposure to water.
Water Damage
After rescuing your key fob from the puddle, pool or washing machine it's been swimming in, clean it of the most water you can by shaking it. Place it on the ground with the button facing downwards, and let it drain for a few minutes while you clean the inside with a soft cloth. This will prevent any condensation from causing damage to the electronic chip.
If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which appears like the car key symbol illuminates then this could indicate a fault with the immobilizer. This is a security feature within the vehicle to deter thieves from hotwiring it. If this is the case, you will need to see a Citroen dealer or a trained mechanic to resolve the problem.
A continuous engine warning light may indicate that the electric power assisted steering system is failing. If this is the situation, then you should stop the car and make sure that the oil pressure is not too high and that the temperature isn't too high prior to resuming it. If the issue persists, you'll need to consult an authorized Citroen dealer or mechanic to address the issue.
Dead Battery
A dead battery in the coin is the most common reason for your key fob to not work in your Berlingo. The button cell in the key can be replaced however, it is essential to select the correct size, voltage, and type of battery. A battery that isn't compatible could cause damage to the circuit board. A dead coin-cell battery can also disable anti-theft. This is a precautionary measure that prevents the engine being started without the physical key.
If the key fob isn't responding to the lock button even after replacing the battery it could be because the receiver module has failed and is not communicating with other modules in your vehicle. A scanner for OBDII can detect this problem.
If the key fob still isn't responding, then you can try reprogramming the key fob. Follow the steps in your owner's manual for this procedure. It should be working fine after it has been reprogrammed.
Diagnostics of a fault
The reliability of the Citroen Berlingo is generally praised by its owners. As with all vehicles there are a few issues that can arise. One of the most common is an inoperable key fob battery. This is an easy issue to recognize and can be resolved in just a few minutes. Other issues include a worn out button, water damage to the electronic chip or signal, interference or a remote system receiver module that is defective.
It is vital to be aware that not all keyfob batteries are the same. Some batteries are made from inferior materials, which can cause damage to your remote, or other electronics. When replacing the battery, only use a battery that is of the same type and voltage as the original. Also, ensure the new battery is fitted correctly. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing towards the upward direction.
If you see an exclamation mark in the shape of the shape of a triangle on the dashboard, it's a sign that there is a problem with your vehicle's electric power assisted driving. If the warning light is illuminated when you drive, we recommend that you seek out a qualified mechanic at an Citroen Berlingo dealer (incl Multispace).
Radio Interference
If your key fob stops working at all it could be as a result of radio interference. This issue can be caused by devices that use the same frequency as remote controls. Some wireless security systems, like LED lights from the aftermarket, could interfere with RF signals. If you own one of these gadgets at home, you can try shifting them to a different area to see if it helps.
Environmental factors can also interfere with the key fobs of cars and other devices that use the same frequency. For instance, metal objects may alter the strength of the signal. Rainy weather can also cause the antenna of the fob to be bent, resulting in a weaker signal. In some instances the key fob might not respond to the radio signals even though it is within range of the vehicle.
To make sure that your key fob is functioning properly examine the battery. It should be in good condition, and the contacts should be free of corrosion. A damaged or corroded connection is the main reason why the fob's keypad does not respond to radio signals coming from the vehicle. A depleted battery can also cause fobs to fail. If you replace the battery and the issue persists, it's a good indication that the antenna is faulty. Locksmiths can check the keyfob, and make repairs.
