They have many different models of cars, but their most popular are the XC40 and S60. The XC40 is the most popular model for them because it is their cheapest model, yet still comes with all of the bells and whistles. It comes with everything you need from a car: safety features, good looks, great gas mileage, and good performance. Volvo has been around for over 90 years and has proven to be a reliable brand when it comes to vehicles.


The overall design of the Volvo XC40 is really nice because it comes with many things that other vehicles don’t have. Among others, it has LED headlights and taillights, parking sensors, keyless entry system, push-button start button (allowing you to start your car without needing to take your keys out), Bluetooth connectivity between your phone and your car stereo system (so you can easily make calls while driving), an amazing cargo space, and of course, great safety features.

Now, there are some issues that people have with this car and one of them is that the key code of the car sometimes does not work. In order to solve this problem, you may need to contact Volvo directly. However, we have some solutions for you in case your key code does not work as well. We are going to show you some ways on how to troubleshoot this problem in case your key code does not work on your Volvo XC40.

The “Key Not Found” Error

The Volvo XC40 has a keyless entry system, which means that you do not need to take your keys out to start the car. However, sometimes your Volvo XC40 might suddenly cut out and give you an error message that says “Key Not Found.” This means that your Volvo failed to detect a corresponding key in its vicinity.


The “Key Not Found” error is actually quite common on most vehicles, and it can happen for many different reasons. However, there are several different ways that you can try to fix this problem on your Volvo XC40.


1) Check on the key fob battery

The first thing that you can do is to check on the key fob battery. This is because sometimes your key fob battery can die and will not be able to detect a key in its vicinity. The good news is that this problem can be easily fixed by simply charging the battery.


Other than charging the battery, you can also just wholly replace the battery. The life of all batteries is short; eventually, they will need to be replaced. However, keep in mind that the battery that powers a key tag cannot be replaced.


If the key tag is not working anymore, then a new tag is needed. It is possible to place orders at any authorized Volvo workshop.


It is also necessary that the key tag that has been ejected from your car system is also deleted in order that no unauthorized users can access the car via the back-up start.


Finally, note that each key battery has a different service life. It will overall depend on how often you use the vehicle or the key. If any of the following conditions are met, then you should replace the battery for your Volvo key.


2) Check on your car battery

If your key code does not work, you may need to replace the battery of your car. The battery is located under the hood of your car. The battery should be changed every six months or so.


One way that you can tell if it is time for a new battery is if the indicator light on the dashboard starts blinking. This means that there is something wrong with your car and that it needs to be checked out. However, we are going to show you how to test the battery first before taking it into a shop for replacement.


To test your Volvo XC40’s battery, all you need to do is put a voltmeter on one of the terminals. A voltmeter will let you know if it’s time for a new battery. If not, then there may be something wrong with your vehicle and you will need to take it into a shop for service or replacement.


3) Just bring your key closer

This is the simplest solution that you can do. All you need to do is just bring your key closer to the car. The key will automatically register to the car system and start working again.


Sometimes, if there are items obstructing the key fob sensor, it may not be able to work. For example, if you have your key deep inside your coat pockets, then the car might not be able to register your key. In this case, you simply need to take your key out of your pocket, put it where it is suggested in your car manual, and try again.


Also, if you are wearing gloves when you are driving and trying to use the key fob sensor, then it may not work. If this happens, then try taking off your gloves and then try again.


4) Interference from other devices

If you are in a crowded area, then the sensor of your key fob may not be able to work. Other devices may be interrupting the connection from your key to your vehicle. This can be anything from your own smartphone, the anti-theft system in your car, or other sources.


If this happens, then you can try restarting your car to see if it can detect your key now. You may also need to momentarily turn off all of the electronic devices that are interfering with your key fob. Try shutting down your phone, for example, and see if that changes anything.

In Conclusion

In conclusion, although there are many different ways that you can try to fix the “Key Not Found” error on your Volvo XC40, the above are some of the most common reasons for it as well as the corresponding best solutions for each issue.


If your key code still does not work on your Volvo XC40, then you should contact Volvo and ask them to configure or replace the key.
