Some keyboard keys (not function keys) do not perform the desired action when pressed. For function keys, make sure the hotkey software is up to date. See Check Drivers or Function keys are not working.

To fix this issue, try the following troubleshooting methods. If the issue is resolved, no need to proceed to the next method.

Step 1 Test if On-Screen Keyboard is workable

  1. click the Ease of access logo.
  2. Place a check in the Type without the keyboard (On-Screen Keyboard) box.
  3. By using your mouse cursor, click and check that all keys are working fine with the On-screen keyboard. Also check the keys that are not working with the physical keyboard.

Step 2 - Disable all Keyboard shortcuts and enhancements

  1. Search for and select Control Panel.
  2. Select Ease of Access\Ease of Access Center\Make the keyboard easier to use.
  3. Uncheck all the boxes and apply the settings, and restart the computer.

Step 3 - Test keys with Notepad

  1. Search for and select Notepad.
  2. Try typing the keys and see if they work or are displayed in Notepad. If the failed keys work, this may be a software issue. Test the failed keys with different software installed on the PC. If the keys fail with a specific software application, refer to the vendor's software instructions and reset the settings.

Step 4 - Check Drivers

Reinstall the keyboard driver.

Step 5 - Disable gaming mode

If gaming mode is enabled, try disabling gaming mode.

Step 6 - Try Keyboard Troubleshooting

Use keyboard troubleshooting.

  1. Right-click the Windows icon.
  2. Select Settings.
  3. Select Update & Security.
  4. Select Troubleshoot. Select Keyboard to fix problems with keyboard settings.

Step 7 - Check if the key works under Command Prompt

  1. Enter Command Prompt.
    1. Press Windows + X, then choose Windows PowerShell (Admin) or Command Prompt (depending on the version of Windows 10) or search for command prompt, and then select Command Prompt.
  2. Under the Administrator: Command Prompt window, test the failed keys.
    1. If the failed keys work, the issue should be caused by software, not PC hardware. Test the failed keys with different software installed on the PC. If the keys fail with a specific software application, refer to the vendor's software instructions and reset the settings.
    2. If the failed keys do not work, the issue may be with the PC hardware.
