Citroen Berlingo Key Fob Troubleshooting
Citroen Berlingo Multispace fills a niche in the market for people carriers. Its sliding rear door makes it easy to fit into parking bays, and its robust cabin can withstand more abuse than the majority of upmarket competitors.
If your key fob was submerged in saltwater or soapy liquid, it may not work in the future, even after replacing the battery and programming. The internal chip has been damaged because of exposure to water.
Water Damage
Shake your key fob to drain as much water as you can. Then, place it with the button side facing up and let it drain for a couple of minutes while you wipe the inside down using a towel. G28CarKeys will prevent any condensation from causing damage to your electronic chip.
If your Mk 2 Citroen Berlingo or Mk 3 Citroen Berlingo dashboard warning light, which looks like a car key symbol, appears to be lit, then it could indicate an issue with the immobilizer. This is a security element inside the vehicle that prevents thieves from hotwiring it. If this is the case you'll need to see a Citroen dealer or a certified mechanic to fix the issue.
An unending engine warning light could mean that the steering system with electric power is not working properly. If this is so, then you should stop the car and ensure that the oil pressure is in good order and that the temperature isn't too high prior to resuming it. If the issue continues then you should visit a Citroen dealer or trained mechanic to resolve the problem.
Dead Battery
A dead battery in the coin is the most common reason for your key fob not to function in your Berlingo. The button cell battery that is in the key is easy to replace, however you should ensure that you are using the correct voltage and size battery. A non-compliant cell could damage the circuit. A dead coin battery may also disable the anti-theft system. This is a precautionary measure that prevents the engine from getting started without the physical key.
If the key fob still isn't responding to the lock button after replacing the battery, it could be because the receiver module has failed and isn't communicating with other modules in your vehicle. This can be confirmed using an OBDII scan tool.
If the key fob is still not responding, you can try reprogramming. Follow the directions in your owner's manual for this procedure. It should work as expected once it has been reset to its original program.
Diagnosis of a Fault
The reliability of the Citroen Berlingo is generally highly praised by its owners. However, like all vehicles there are a few issues that occur. One of the most common is an inoperable key fob battery. It is a simple issue to identify and can be resolved within a matter minutes. Other problems that can arise include 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 remember that not all key fob batteries are identical. Certain batteries are made of inferior materials that can damage your remote or other electronics. When replacing the battery, you should make sure you use a battery of the same voltage and type as the original. Also, ensure the new battery is installed correctly. When inserting the battery into the slot, make sure the positive (+) face of the battery is facing towards the upward direction.
If you see an exclamation mark in the shape of an oval on the dashboard, it's a sign that there is a problem with your vehicle's electric power assisted driving. If the warning light illuminates during driving, it is advised that you seek advice from a trained mechanic or Citroen Berlingo (incl Multispace) dealership.
Radio Interference
If your key fob stops working all of a sudden it could be a result of radio interference. This is a problem that can be caused by devices that operate on the same frequency as remote controls. Some wireless security devices, such as LED lights sold on the market, can interfere with RF signals. If you have any of these at home, you can try moving them to another room to see if this helps.
Environmental elements can also impact the key fob of automobiles, in addition to devices that use the same frequency. For instance, metal objects can alter the strength of the signal. Weather conditions that are rainy can cause the antenna of the key fob to bend, leading to an ineffective signal. In some instances, even when the fob's location is close to the car it might not respond to radio signals.
To ensure that your key fob is healthy make sure you check the battery. It must be in good working order, and the contacts should be free of corrosion. A corroded contact is an important reason for a key fob not responding to radio signals. A drained battery can also cause the fob to malfunction. If the issue is still present after replacing the battery the antenna may be malfunctioning. A locksmith can look over the keyfob and fix it.
