Volume Key Not Working? Try These Fixes

We don’t realize it, but most of us have our own set of keyboard habits. While we know we can change the volume with the taskbar, the keyboard way seems a little less complex.

So, if your keyboard volume button isn’t working, it could be a little annoying. But there’s a simple solution to this minor inconvenience.

If none of the keys on your keyboard are working then this could be a hardware issue. But if it’s just the volume key that’s showing the issue, then it could be a glitch in the driver, windows services, or system files.

As this is a common recurring issue for PC users, we have compiled a list of solutions that will cover all possible causes of the volume keys not working. Try each one and see if it works for you.

Common Causes of Volume Key Not Workings

  • Faults in Keyboard DriverIssues with Human Interface Device Service (windows service)
  • System Files relating to Keyboard are corrupt or missing.
  • Function Lock is turned on.
  • Third-party software conflicting with Keyboard’s input command to the device
  • Problems in USB Port (USB keyboard Specific)

How to Fix Volume Key Not Working in Windows PC? 

The fixes stated below are centered towards troubleshooting keyboard errors in windows. These alternatives should work for both inbuilt or external keyboards.

Start by Restarting the Device

Restarting a device gives a fresh start to all processes on the PC. If there were errors in the previous session that caused the volume key issue, there is a high chance that it might get fixed when the PC starts up again.

We recommend doing this for both windows, macs. For ones using external keyboards, we suggest plugging it off and then re-plugging it on the USB port after the PC restarts.

Check if the Function Lock is Enabled

When the function lock is on, the F1-F12 keys work. When the function key is off, the secondary functions of the F1-F12 get enabled.

E.g., When the function lock is off in an Acer predator helios 300, the F8 can serve as a mute option.

In most PCs, we can turn the function lock on through a combination of keys. Some use FN+Shift or FN+ESC. It differs from PC to PC.

There is a chance that we might have accidentally pressed a combination of keys to turn this function lock on, which stopped the function keys from allowing their secondary function.

Google the Function lock key combination for your computer and see if the volume button works. There is a chance that you won’t find a combination that unlocks the function lock. 

In such instances, follow the procedure below.

  2. Under System located on the left panel, select recovery.

Set Human Interface Device to Automatic & Restart Service

The human interface device service is responsible for letting us interact with the Pc through input or output devices. A keyboard is an input HID device. 

If there are issues with the HID, sending input commands to the computer is compromised, so certain keys might not work in this instance. This is applicable for both USB and inbuilt keyboards.

To fix this, make sure the startup type settings of HID are set to automatic and restart the service.

  1. Press Windows Key, search & select Services.

Uninstall any third Party Keyboard Applications

Many users opt for third-party keyboard software that can assign functions and customized commands to keys. 

Under normal circumstances, it’s users’ choice regarding software, but if you face volume keys not working, the app might be conflicting with the Keyboard’s input.

If you face the volume keys not working, we recommend uninstalling any third-party keyboard software and checking if the issues are resolved. We can always install them back in if needed later.

Update or Uninstall/ Reinstall Keyboard Driver

Faults or Glitches in the Keyboard driver may also create issues with keys not working. We recommend uninstalling and reinstalling it.

  3. Right-click on the driver, and select Uninstall device.Keyboard Device Driver

The solutions stated above should be enough to make the volume button work. In the worst-case scenario, we recommend resetting the windows.
