A malfunctioning key fob can be incredibly frustrating, especially when you’re trying to get on the road with your 2018 Volvo XC90. If you’re experiencing issues with your key fob not working, don’t panic! This article will delve into the common culprits behind this problem and provide you with effective solutions to get you back in the driver’s seat.
Understanding the 2018 Volvo XC90 Key Fob
Before we jump into the troubleshooting steps, it’s helpful to understand the technology behind your Volvo XC90 key fob. The key fob utilizes a radio frequency identification (RFID) system to communicate with your vehicle. This system allows for keyless entry and ignition, providing both convenience and security. When you press a button on your key fob, it transmits a specific signal to your car’s receiver. If the signal is recognized, the corresponding action is performed, such as unlocking the doors or starting the engine.
Common Causes of a Malfunctioning Key Fob
There are a number of reasons why your 2018 Volvo XC90 key fob may not be working correctly. Here are some of the most common culprits:
1. Dead Key Fob Battery
This is perhaps the most frequent reason for key fob failures. Like any electronic device, your key fob relies on a battery to power its functions. Over time, the battery naturally drains, eventually leading to a complete loss of power.
How to Check: If your key fob is completely unresponsive, a dead battery is the most likely cause. Some Volvo XC90 key fobs have a built-in indicator light that flashes red when the battery is low.
2. Key Fob Out of Range
While the RFID system in your key fob has a decent range, there are limitations. If you’re too far away from your vehicle, the signal strength may be insufficient for the receiver to detect.
How to Check: Try moving closer to your vehicle and pressing the key fob button again. If it works, you were simply out of range.
3. Faulty Key Fob Buttons
Repeated pressing and general wear and tear can take a toll on the physical buttons of your key fob. Over time, the buttons may become worn out, misaligned, or even cease to function altogether.
How to Check: Inspect the buttons closely for any visible signs of damage or misalignment. If a button feels stuck or unresponsive, it might be the culprit.

4. Key Fob Programming Issues
The key fob for your 2018 Volvo XC90 needs to be properly programmed to sync with your vehicle’s security system. If the programming is lost or corrupted, the key fob may not be recognized by your car.
How to Check: Try using your spare key fob if you have one. If the spare key fob works, it’s a strong indication that the original key fob has a programming error.
5. Receiver Module Problems
Your Volvo XC90 is equipped with a receiver module that’s responsible for detecting and interpreting the signals sent from your key fob. If this module malfunctions, it may not be able to receive or process the signals correctly.
How to Check: Diagnosing a faulty receiver module requires specialized equipment and expertise. If you suspect this to be the issue, it’s recommended to consult with a qualified automotive locksmith or dealership.
Troubleshooting and Solutions
Now that we’ve explored the common causes, let’s dive into the potential solutions:
1. Replace the Key Fob Battery
If you suspect a dead battery, replacing it is a quick and easy fix. Refer to your owner’s manual for instructions on how to open the key fob and the type of battery it uses.
2. Reprogram the Key Fob
Reprogramming your Volvo XC90 key fob often requires following a specific sequence of steps outlined in your owner’s manual. However, newer models may require professional equipment and expertise.
3. Repair or Replace the Key Fob
If the key fob buttons are physically damaged or if reprogramming doesn’t resolve the issue, you may need to consider repairing or replacing the key fob.
4. Consult a Professional
For issues like receiver module problems or complex programming errors, it’s always best to consult with a professional automotive locksmith or dealership. They have the knowledge and tools to diagnose and fix the problem efficiently.
