Citroen Berlingo Key Fob TroubleshootingCitroen’s Berlingo Multispace occupies a utilitarian niche in the people carrier market. Its sliding doors at the rear allow it to be squeezed into parking bays and its sturdy cabin is more bashing-proof than many of the more expensive rivals.However, if the device has bathed in soapy or salt water, it might not function again, even after a new battery and programming. The internal chip has been damaged by exposure to water.Water DamageAfter you have rescued your key fob from the puddle, pool or washing machine it was swimming in, clean it of as much water as you can by shaking it. Lay it down with the button facing down, and let it drain for a couple of minutes before wiping the inside using a soft cloth. This should stop any condensation from causing damage to the electronic chip.If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which looks like an automobile key symbol is lit, it could be indicating an issue with the immobilizer. This is a security device in the vehicle that prevents thieves from wiring hotspots. If this is the situation you’ll have to visit a Citroen dealer or a trained mechanic to solve the issue.A constant engine warning light could indicate that the electric power assisted steering system is failing. If this is the situation you need to stop the car and test the temperature and pressure of your oil before restarting it. If the issue continues, you’ll need to consult an expert Citroen technician or mechanic in order to resolve the problem.Dead BatteryThe most frequent reason for the key fob not functioning inside your Berlingo is a dead coin battery. The button cell battery in the key is very simple to replace, but you must ensure that you choose the right voltage size and type of battery. A non-compatible cell can damage the circuit. A dead coin-cell battery could also disable anti-theft. This is a security function that prevents the engine from starting without a physical key.If the key fob does not respond 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. An OBDII scanner can help diagnose the issue.If the key fob is still not responding, try reprogramming. Follow the steps in your owner’s manual for this procedure. It should work as expected once it is updated.Diagnosis of a FaultCitroen Berlingo owners are generally pleased with the reliability of the car. However, like all vehicles there are a few issues that occur. A dead key fob is among of the most common problems. Fortunately, this is easy to find and is easily replaced 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 important to know that not all key fob batteries are made identical. Some batteries are made of inferior materials and can damage the remote key fob, or other electronic components in your vehicle. Make sure you use batteries that are of the same type and voltage as the original when replacing the battery. Make sure The Keylab is inserted correctly. Ensure the positive (+) side of the battery faces upwards when it is placed in the slot for the battery.If you notice a warning light on your dashboard which appears like an exclamation point, this signifies that the vehicle has detected problems with its electric power-assisted steering. If this warning light comes on while you are driving then we recommend that you seek out a certified mechanic at a Citroen Berlingo dealer (incl Multispace).Radio InterferenceIf your key fob has stopped working at all it could be a result of radio interference. This is a problem that could be caused by devices that operate on the same frequency as remote controls. For instance, wireless security systems as well as aftermarket LED lights can interfere with radio signals. If you have one of these gadgets at home, you can try moving them to another room to see if they help.Environmental factors can also affect the key fob of the car, in addition to devices that use the same frequency. For instance, metal objects may interfere with the signal’s strength. Rainy weather can also cause the antenna of the key fob to be bent, resulting in an ineffective signal. In some cases, even when the fob is located close to the vehicle it may not be able to respond to radio signals.To ensure that your key fob is functioning properly examine the battery. It should be in good condition and the contacts must be free of corrosion. A damaged connection is the main reason the keyfob isn’t responding to radio signals coming from a vehicle. A depleted battery could cause a fob to malfunction. If the issue is still present after replacing the battery, the antenna may be faulty. A professional locksmith can examine the key fob and make the necessary repairs.
