How to Unlock a Keyboard on a Windows 10 Laptop (8 Fixes)

A laptop keyboard that suddenly stops typing in Windows 10 is usually not broken. Most of the time it has been "locked" by a keyboard shortcut, an accessibility feature, a function key, or a driver glitch. This guide walks through every common cause, from the quickest checks to driver and hardware fixes, so you can get your keyboard working again.

Quick Answer

First, restart your laptop. If the keyboard still does not work, turn off Filter Keys and Sticky Keys in Settings > Ease of Access > Keyboard, press Num Lock if letters type numbers, and look for a keyboard lock key on your laptop (often a padlock icon used with Fn). If that fails, reinstall the keyboard driver in Device Manager.

Keyboard works in BIOS but not in Windows	Windows driver or software	Steps 6 and 7
Keyboard does not work anywhere	Hardware issue	Step 8

Step 1: Restart the Laptop

A simple restart clears many temporary glitches. Use the mouse or touchpad: click Start > Power > Restart. If Windows is frozen, hold the power button for about 10 seconds to force a shutdown, wait a few seconds, and turn it back on.

You can type with the On-Screen Keyboard in the meantime: click Start > Windows Ease of Access > On-Screen Keyboard, or go to Settings > Ease of Access > Keyboard and turn on Use the On-Screen Keyboard. You can also sign in with it using the Ease of Access icon on the sign-in screen.

Step 2: Turn Off Filter Keys and Sticky Keys

Filter Keys ignores brief or repeated keystrokes, which makes a keyboard seem dead. It turns on if you hold the right Shift key for eight seconds and accept the prompt. Sticky Keys turns on after pressing Shift five times.

1. Open Settings with the mouse (Start > gear icon).
2. Go to Ease of Access > Keyboard.
3. Turn off Use Filter Keys.
4. Turn off Use Sticky Keys.
5. Uncheck Allow the shortcut key to start Filter Keys and Allow the shortcut key to start Sticky Keys to prevent it happening again.

Step 3: Check Num Lock, Fn Lock, and Other Lock Keys

• Num Lock: on compact laptops, letters like J, K, L, U, I, and O can double as a number pad. If they type numbers, press Num Lock, or Fn + Num Lk (sometimes Fn + F11 or Fn + Scroll Lock, depending on the model).
• Fn Lock: if the top row controls volume or brightness instead of F1 to F12, or the reverse, press Fn + Esc (a common Fn Lock toggle on many laptops) or check your laptop's manual.
• Caps Lock and Scroll Lock: check that no unexpected indicator lights are on.

Step 4: Look for a Keyboard Lock Shortcut

Some laptops include a dedicated key combination that disables the built-in keyboard, often marked with a padlock or keyboard icon on one of the function keys. If you see one, press it together with Fn. The exact key varies by manufacturer and model, so check the key icons or the support page for your laptop. If you want to disable the built-in keyboard on purpose, here is how to disable the laptop keyboard on Windows 11.

Also check any manufacturer utility (keyboard or hotkey software that came with the laptop), since some let you disable the keyboard or change key behavior.

Note: Windows key + L locks your whole PC, not the keyboard. If you see the lock screen, just sign in again.

Step 5: Clean the Keyboard and Check for Stuck Keys

A stuck key, especially Shift, Ctrl, or Alt, can make every other key behave strangely. Shut down the laptop, tilt it, and gently use compressed air between the keys. Press each modifier key a few times to make sure none is stuck. If you spilled liquid on the keyboard, power off immediately, unplug it, and let it dry completely before trying again.

Step 6: Reinstall or Update the Keyboard Driver

1. Right-click Start and select Device Manager.
2. Expand Keyboards.
3. Right-click your keyboard (usually Standard PS/2 Keyboard or HID Keyboard Device) and choose Uninstall device. Confirm.
4. Restart the laptop. Windows reinstalls the driver automatically.

If that does not help, right-click the keyboard and choose Update driver > Search automatically for drivers, or download the latest keyboard and chipset drivers from your laptop maker's support page. A yellow warning icon next to the keyboard in Device Manager is a strong sign of a driver issue.

Step 7: Run the Keyboard Troubleshooter and Check Software

1. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
2. Select Keyboard and click Run the troubleshooter.

Then try these:

• Turn off Fast Startup: go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable, uncheck Turn on fast startup, and save. Fast Startup can sometimes stop the keyboard from initializing properly.
• Install Windows updates: go to Settings > Update & Security > Windows Update.
• Check for recently installed software that remaps keys or blocks input, and uninstall it.
• Boot into Safe Mode: if the keyboard works there, a startup program or third-party driver is likely the cause.

Step 8: Test for Hardware Problems

• Test in BIOS/UEFI: restart and press the setup key (often F2, F10, Del, or Esc, depending on the maker). If the keyboard can navigate the BIOS, the hardware works and the problem is in Windows.
• Try an external USB keyboard. If it works, you can keep using the laptop while you troubleshoot the built-in keyboard.
• Check the battery: a swollen battery can push up on the keyboard from below. If the keyboard or touchpad is bulging, stop using the laptop and get it serviced.
• If the built-in keyboard does not work even in BIOS, the keyboard or its internal cable may need repair. Contact the manufacturer, especially if the laptop is under warranty.
