Keyboard Keys Not Working on Windows 10? Fixes

Guide 10-16558 · Updated · Step by step

If some or all of your keyboard keys are not working on Windows 10, the fix is usually either a driver update, a quick settings change, or cleaning the keyboard. Start by restarting your PC and checking if the issue is hardware or software using the on-screen keyboard.

Why Do Keyboard Keys Stop Working?

Keys can stop responding for several reasons, and the right fix depends on the cause. The most common culprits are:

  • Sticky or spilled liquids – a single key or a cluster of keys may stick or short out.
  • Outdated or corrupted drivers – Windows may have installed a bad update or the driver is old.
  • Filter Keys or Sticky Keys enabled – these accessibility features can alter how key presses are registered.
  • Wrong keyboard layout or language – keys may type different characters or nothing at all.
  • Hardware failure – the keyboard itself may be damaged or the connection port is faulty.
  • Wireless interference or low battery – for Bluetooth or 2.4GHz wireless keyboards.

Before trying any software fixes, rule out a hardware issue. Plug the keyboard into a different USB port (or another computer) and see if the problem follows. For laptops, try an external USB keyboard – if that works, the built-in keyboard hardware or its cable is likely the issue.

Quick Checks to Try First

These simple steps resolve many temporary glitches:

  1. Restart your PC – a full shutdown and reboot clears driver and service hiccups.
  2. Unplug and reconnect – for wired keyboards, unplug for 10 seconds; for wireless, remove the USB receiver or turn the keyboard off and on.
  3. Check the battery – replace or recharge if the keyboard is wireless.
  4. Test with the on-screen keyboard – open Settings > Ease of Access > Keyboard and turn on “Use the On-Screen Keyboard.� If the on-screen keys work, the physical keyboard is likely defective.
  5. Clean the keyboard – turn it upside down and gently tap, or use compressed air to remove debris. For sticky keys, dampen a cotton swab with isopropyl alcohol and wipe around the affected key.

If the problem persists after these, move on to the software fixes below.

Update or Reinstall the Keyboard Driver

A corrupted or outdated driver is a frequent cause. Here’s how to fix it:

  1. Right-click the Start button and select Device Manager.
  2. Expand Keyboards, right-click your keyboard device, and choose Update driver.
  3. Select Search automatically for updated driver software and follow the prompts.
  4. If Windows says the best driver is already installed, try Uninstall device instead, then restart your PC. Windows will reinstall the driver automatically on boot.

For laptops, also check the manufacturer’s support page for a specific keyboard driver or BIOS update. Sometimes a Windows Update introduces a bug; uninstalling the recent update can help.

Disable Filter Keys and Sticky Keys

Windows 10 includes accessibility features that can interfere with normal typing:

  • Filter Keys – ignores brief or repeated keystrokes, making it seem like keys are missing.
  • Sticky Keys – makes modifier keys (Shift, Ctrl, Alt) “stick� until another key is pressed, which can cause unexpected behavior.

To turn them off:

  1. Go to Settings > Ease of Access > Keyboard.
  2. Turn off Use Filter Keys and Use Sticky Keys.
  3. Also uncheck “Show the Filter Keys icon on the taskbar� and “Show the Sticky Keys icon on the taskbar� to prevent accidental toggling.

These features are often triggered by holding down Shift for 8 seconds or pressing Shift five times – a common accidental cause.

Check Keyboard Layout and Language Settings

If keys are typing the wrong characters or nothing at all, the layout may have changed. For example, a US layout is different from a UK layout. To check:

  1. Open Settings > Time & Language > Language.
  2. Under Preferred languages, click your language and select Options.
  3. Under Keyboards, ensure the correct layout is installed (e.g., US QWERTY).
  4. If multiple layouts exist, press Windows key + Spacebar to cycle between them and see if that fixes the issue.

Also check the Region settings – sometimes a mismatch causes the layout to default to a different one. For laptops, some models have a function (Fn) key that toggles the number pad overlay, making certain letters type numbers instead. Look for a key with a padlock or “NumLk� icon and press Fn + that key to disable it.

Run the Keyboard Troubleshooter

Windows 10 has a built-in troubleshooter that can automatically detect and fix common keyboard problems.

  1. Open Settings > Update & Security > Troubleshoot.
  2. Select Keyboard from the list and click Run the troubleshooter.
  3. Follow the on-screen instructions. It may reset settings or suggest driver fixes.

This tool isn’t a cure-all, but it’s worth trying before more advanced steps.

When It’s a Hardware Problem

If none of the software fixes work, the keyboard is likely physically damaged. Signs include:

  • Keys feel loose, sticky, or require excessive force.
  • The issue follows the keyboard when plugged into another computer.
  • Laptop keyboard issues persist even with an external keyboard working.
  • Liquid was spilled on the keyboard.

For a desktop keyboard, replacement is usually inexpensive. For a laptop, you can either replace the keyboard module (often available online) or use an external USB keyboard as a permanent workaround. If the laptop is under warranty, contact the manufacturer.

Frequently Asked Questions

Why are my number keys not working?
Number keys can fail due to the Num Lock toggle. On many laptops, pressing Fn + NumLk turns on a number pad overlay where some letter keys become numbers. If the number row itself isn’t working, it’s more likely a hardware issue or a driver problem – try the driver update steps above.

How do I fix a single key that isn’t working?
First, clean under the key with compressed air or isopropyl alcohol. If that doesn’t help, the key’s membrane or switch may be dead. On a desktop, you can swap the keycap with a less-used key (like Scroll Lock) to test. On a laptop, a single key failure often requires replacing the whole keyboard.

Can a virus cause keyboard keys to stop working?
While malware can install keyboard filters or remap keys, it’s rare. More often, a third-party utility like a keyboard remapper or gaming software (e.g., Razer Synapse, Logitech G Hub) interferes. Check for such software and disable or uninstall it to see if the problem resolves.

Why does my keyboard work in BIOS but not in Windows?
If the keyboard works during boot but not in Windows, it’s a driver or software issue. Try booting into Safe Mode (hold Shift while clicking Restart, then choose Troubleshoot > Advanced options > Startup Settings > Restart, then press 4). If the keyboard works in Safe Mode, a third-party driver or service is the culprit.

Should I use a USB keyboard on a laptop with broken keys?
Yes, a USB or Bluetooth keyboard is a quick and reliable workaround. It won’t fix the built-in keyboard, but it lets you continue working immediately. For a permanent fix, consider replacing the laptop keyboard.

How do I reset the keyboard settings to default in Windows 10?
Go to Settings > Devices > Typing and turn off any toggles like “Show text suggestions� or “Add a space after I choose a text suggestion.� Also reset the language settings by removing and re-adding your preferred keyboard layout. There’s no single “reset� button, but these steps usually restore normal behavior.
