Citroen Berlingo Key Fob Troubleshooting
Citroen's Berlingo Multispace occupies a utilitarian niche in the people carrier market. Its sliding rear doors allow it to easily squeeze into parking bays, and its durable cabin is more smack-proof than many of the more expensive rivals.
If your key fob was submerged in saltwater or soapy water it might not function in the future, even after replacing the battery and programming. The internal chip is damaged due to exposure to water.
Water Damage
After getting your key fob back from whatever pool, puddle or washing machine it's been swimming in, clean it of as much water as you can by shaking it. Then, lay it on the button side down and let it drain for a couple of minutes while you wipe the inside using a towel. This should prevent any condensation from damaging the electronic chip.
If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which looks like a car key symbol, lights up, it could be a fault with the immobilizer. This is a security element in the vehicle to prevent thieves from stealing it. If this is the case then you will need to go to an Citroen dealer or a trained mechanic to fix the issue.
A constant engine warning light may indicate that the electric power assisted steering is malfunctioning. If this is the case, you should stop the vehicle and check the oil pressure and temperature prior to resuming it. If the issue continues then you must visit a Citroen dealer or a qualified mechanic to resolve the issue.
Dead Battery
The most frequent cause of the key fob not working in your Berlingo is the battery in the coin is dead. The button cell in the key can be replaced easily, but it is important to use the right size, voltage and type of battery. A cell that is not compatible can cause damage to the circuit. A dead coin-cell battery can also disable the anti-theft feature. This is a security function that prevents the engine from starting without a physical key.
If the key fob isn't responding to the lock button after replacing the battery it could be that the receiver module is faulty and isn't communicating with other modules in your vehicle. An OBDII scanner can help diagnose this problem.
If the key fob isn't working, you can try reprogramming the key fob. To do this, follow the steps in your owner’s manual. It should be working fine after it is changed.
Fault Diagnosis
Citroen Berlingo owners are generally satisfied with the reliability of the car. However, as with all vehicles there are a few issues that arise. One of the most common is the battery for the key fob that is dead. It is a simple issue to recognize and can be repaired in a matter of minutes. Other problems that can arise are a worn button or button, water damage to the electronic chip, signal interference, or a remote keyless system receiver module that has developed a fault.
It is important to realize that not all keyfob batteries will be the same. Certain batteries are made of inferior materials, which can cause damage to your remote, or other electronics. Make sure to use only batteries of the same kind and voltage as the original when replacing the battery. Make sure that the new one fits properly. Ensure the positive (+) side of the battery faces upwards when inserted into the slot for the battery.
If G28CarKeys notice an exclamation point in the shape of the shape of a triangle on your dashboard, it is a sign that there is a problem with the electric power-assisted driving system in your vehicle. If this warning light comes on while you're driving, we recommend that you seek out a certified mechanic at an Citroen Berlingo dealer (incl Multispace).
Radio Interference
If your key fob isn't working all of a sudden it could be as a result of radio interference. This issue could be caused by devices operating on the same frequency as a remote control. Certain wireless security devices, such as LED lights from the aftermarket, could interfere with the RF signal. If you have any of these at home, try shifting them to a different area to see if they help.
Environmental elements can also impact the key fob in cars as well as other devices with the same frequency. Metal objects, for instance can impede the strength of the signal. Rainy weather may also bend the antenna of the fob, resulting in a weaker radio signal. In some instances the key fob might not respond to radio signals even when it is located near the vehicle.
To make sure that your key fob is functioning properly examine the battery. The battery should be in good working order and the contacts should not be affected by corrosion. A corroded or damaged connection is the main reason the keyfob isn't responding to radio signals from vehicles. A drained battery can also cause the fob to malfunction. If the issue persists after replacing the battery the antenna may be faulty. A locksmith can examine the keyfob and make repairs.
