Citroen Berlingo Key Fob Troubleshooting
Citroen's Berlingo Multispace occupies a utilitarian niche in the people carrier market. Its sliding rear door allows it to be easily inserted into bay parking spaces and its durable cabin is more durable than many of the more expensive competitors.
If your key fob was submerged in saltwater or soapy liquid the device may not function again even after a new battery and the reprogramming. The internal chip is damaged from exposure to water.
Water Damage
Shake your key fob to drain as much water as you can. Lay it flat with the button side down and leave it to drain for a short time while you wipe the inside using a cloth. This will stop any condensation from causing damage to your electronic chip.
If the dashboard warning light that appears like a vehicle with an image of a key illuminates on your Mk 2 or Mk 3 Citroen Berlingo then it could indicate an immobilizer malfunction. This is a security feature inside the vehicle that prevents thieves from wiring hotspots. If this is the situation, you will be required to visit an Citroen dealer or a trained mechanic to fix the issue.
A constant engine warning light may indicate that the electric power assisted steering system is malfunctioning. If this is the case then you must stop the car and ensure that the oil pressure is not too high and that the temperature isn't overly high prior to resuming it. If the problem persists then you'll need to visit a Citroen dealer or trained mechanic to resolve the problem.
Dead Battery
A dead coin battery is the most common reason for your key fob not to work in your Berlingo. The button cell in the key can be replaced, 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 battery for a coin-cell could also disable anti-theft. This is a precautionary measure that prevents the engine from getting started without the physical key.
If the key fob is still not responding to the lock button despite replacing the battery, it could be an unreliable receiver module that isn't communicating with other modules in your vehicle. This can be diagnosed with an OBDII scan tool.
If the key fob is not responding, you could try reprogramming it. To do this, follow the directions in the owner's manual. It should work as expected once it has been reset to its original program.
Diagnostics of a fault
The reliability of the Citroen Berlingo is generally praised by its owners. Like all vehicles, it is possible for faults to occur. One of the most common is the battery for the key fob that is dead. Fortunately, this is easy to identify and is easily replaced within a few minutes. Other issues that could arise are a worn button or a water damage to an electronic chip, signal interference, or a remote keyless system receiver module that has developed an issue.
It is important to know that not all keyfob battery types are the same. Some batteries are made of inferior materials and can damage your remote key fob as well as other electronic components inside your vehicle. When replacing the battery, make sure you make sure that the battery is of the same voltage and type as the original. Make sure the new battery fits correctly. When inserting the battery into the slot, ensure that the positive (+) face of the battery is facing towards the upward direction.
If citroen key programming notice an indicator light on the dashboard of your car that appears to be a triangle with an exclamation point, this indicates that your vehicle has detected an issue with its electronic power-assisted steering. If this warning illuminates while driving, it's recommended that you seek help from a qualified mechanic or Citroen Berlingo (incl Multispace) dealership.
Radio Interference

If your key fob has stopped functioning at all it could be a result of radio interference. This is a common issue caused by devices that operate on the same frequency as your remote control. Certain wireless security systems, like LED lights from the aftermarket, could interfere with RF signal. Try moving these devices into another location if you have them at home.
In addition to devices that utilize the same frequency, there are also environmental factors that can hinder the operation of a key fob. For instance, metal objects could alter the strength of the signal. Weather conditions that are rainy can make the fob's antenna be bent, resulting in weaker signals. In some instances, the key fob may not respond to radio signals, even if it is located near the vehicle.
To make sure that your key fob is in good health examine the battery. The battery should be in good shape and the contacts shouldn't be corroded. Contacts that are corroded are a major cause of a key fob that is not responding to radio signals. A depleted battery may cause a fob to malfunction. If the issue continues to persist after replacing the battery, the antenna may be faulty. A locksmith can inspect the keyfob and make repairs.
