How to Lock Keyboard

Everyone has moments when they need to step away from their computer but worry about accidental keystrokes or curious little fingers typing away at the keyboard. Whether you want to clean your keyboard without the worry of pressing keys, prevent children from messing with your documents, or simply secure your computer while away, keyboard locking is a useful trick to know. Locking your keyboard can reduce the risk of unintended actions and give you peace of mind. Now, let’s go through several effective ways to secure your keyboard with ease.

Use the Built-in Windows Lock Feature

Windows offers a quick and easy way to lock your entire system, which naturally includes the keyboard. By using this inbuilt feature, you can ensure that no accidental keystrokes occur while your computer remains unattended.

Detailed Steps:

  1. Using the Keyboard Shortcut:

    • Simply press the Windows key + L on your keyboard. Your computer will lock, and you will be taken to the lock screen.
    • To unlock your computer, press any key on the keyboard (which won’t be registered as a command) or move the mouse to bring up the login screen, where you’ll enter your password.
  2. Locking Through the Start Menu:

    • Click on the Start button in the bottom left corner of your screen.
    • Select your user icon or name, usually located at the top of the Start menu.
    • Click on Lock.


Using the Windows lock feature is simple and effective. It quickly disables the keyboard and is ideal for short absences. However, when the system is locked, all other activity is halted, and other users cannot use the computer until it is unlocked.

Keyboard Lock Utility Software

There are third-party software utilities available that are designed to lock your keyboard without affecting other computer activities. Some popular options include “KidKeyLock” and “Keyboard Locker.”

Detailed Steps:

  1. Downloading the Software:

    • For instance, you can download KidKeyLock from its official website.
    • Once downloaded, proceed with the installation by following the on-screen instructions.
  2. Using the Software:

    • Run the program after installation.
    • Customize the settings according to your needs to lock the keyboard completely or partially.


This method provides more customization for keyboard locking. The downside is that downloading and learning new software can be daunting for some users, and there’s always a slight risk involved when downloading third-party applications.

Device Manager

You can disable the keyboard through Device Manager in Windows, effectively locking it. This method is slightly more technical and is ideal if you need a more permanent solution.

Detailed Steps:

  1. Open Device Manager:

    • Right-click the Start button and choose Device Manager from the menu.
    • Double-click on Keyboards to expand the category.
  2. Disable the Keyboard:

    • Right-click on the keyboard item listed (it may say “Standard PS/2 Keyboard” or something similar) and select Disable device.
    • Confirm the action in the warning popup by clicking Yes.


This is a more heavy-duty solution that can be useful for long-term situations. However, re-enabling the keyboard will require you to reverse the process, which may not be convenient for frequent use.

Hotkey Combination

Some keyboard-focused software or drivers allow you to set a combination of keys to toggle the keyboard on or off.

Detailed Steps:

  1. Install Supporting Software:

    • For example, you might use a program like SharpKeys to remap keys or create hotkeys.
    • After installing, follow the program’s instructions to set a hotkey for locking the keyboard.
  2. Using the Hotkey:

    • Whenever you need to lock the keyboard, use the hotkey combination you set up.
    • To unlock it, simply press the combination again.


Hotkeys can provide a rapid way to lock the keyboard. The downside is the need to remember the specific key combination, which might not be ideal for those who struggle with memorization.

BIOS Settings

In the BIOS settings of your computer, you can find options to manage the hardware of your system, including the keyboard.

Detailed Steps:

  1. Enter BIOS:

    • Restart your computer and press the BIOS entry key. This is usually one of the function keys (like F2, F10, F12) or DEL, but it varies by manufacturer.
    • Once in the BIOS, use your arrow keys to find the keyboard settings.
  2. Adjust Settings:

    • Within the keyboard settings, look for an option to disable the keyboard. Note that not all BIOS setups provide this option.
    • Save your changes and exit the BIOS.


BIOS adjustments provide a very deep level of control; however, it should be used cautiously as it involves system-level changes and can affect your computer’s boot process.

Screen Saver or Power Settings

You can use your screen saver or power settings to require a password when the system is awakened, which indirectly locks your keyboard.

Detailed Steps:

  1. Adjust Power Settings:

    • Go to Control Panel > Power Options.
    • Click on Require a password on wakeup and set it to Yes.
  2. Modify Screen Saver:

    • Right-click on the desktop and select Personalize.
    • Click on Screen Saver at the bottom of the window and choose a screen saver.
    • Check the box On resume, display logon screen.


This method locks the keyboard when not in active use, primarily during periods of inactivity. It is user-friendly but not as secure since any interaction with the mouse or keyboard will prompt the login screen.

Physical Keyboard Locks

Physical locks exist for keyboards, which can prevent keys from being pressed. These are usually plastic covers that lock into place over the keyboard.

Detailed Steps:

  1. Purchase a Keyboard Lock:

    • Find a suitable keyboard lock or cover from an online store or a local computer accessory retailer.
    • Ensure it’s the right size and compatible with your keyboard.
  2. Install the Keyboard Lock:

    • Place the lock over the keyboard and follow the product instructions to lock it into place.


Physical locks can be very effective, particularly in public or work environments. They are also simple to use but may not be suitable for all keyboard types and are an additional cost.

On-Screen Keyboard

Using the On-Screen Keyboard in Windows ensures that your physical keyboard can be idle.

Detailed Steps:

  1. Enable On-Screen Keyboard:

    • Go to Settings > Ease of Access > Keyboard and turn on the On-Screen Keyboard.
  2. Use the On-Screen Keyboard:

    • With the On-Screen Keyboard open, you can handle basic typing tasks without a physical keyboard, thus reducing the likelihood of accidental keystrokes.


This method keeps the physical keyboard unused but accessible if needed. It is more of an indirect solution and may not be practical for all types of work.

Parental Control Software

Parental control software often has features that can lock the keyboard at scheduled times or after certain periods of inactivity.

Detailed Steps:

  1. Choose Parental Control Software:

    • Research and select a trustworthy parental control application that suits your needs.
  2. Configure the Software:

    • Install the software, create an account, and go through the setup process to schedule keyboard locking times or set up activity-based locks.


This is a great option for parents who wish to control their children’s computer usage. However, it requires setup time and monitoring, and it isn’t a quick toggle option for keyboard locking.

Scheduled Locking Scripts

Advanced users can write or find scripts to lock the keyboard automatically at scheduled times using Task Scheduler in Windows.

Detailed Steps:

  1. Create a Script:

    • Write a script using a programming language like PowerShell or find a pre-made script online that locks the keyboard.
  2. Schedule the Script:

    • Use Task Scheduler to run the script at specific times automatically.


Scheduled scripts are powerful and customizable but require some technical knowledge to set up correctly. They are not user-friendly for those unfamiliar with scripting or task scheduling.

Keyboard Cleaning Mode

Some modern keyboards come with a unique function specifically designed for cleaning, which disables the keys temporarily.

Detailed Steps:

  1. Enable Cleaning Mode:
    • Consult your keyboard’s user manual to find out if it has a cleaning mode and how to activate it.


The cleaning mode is an excellent feature when available but is limited to specific keyboard models that include this function.

In conclusion, whether you are taking a break, cleaning your keyboard, or ensuring your children don’t send emails on your behalf, there are multiple ways to lock your keyboard. The suitable method for you depends on your individual needs, ranging from simple hotkey functions, through third-party software, to BIOS settings for the more technically adept. Just remember, the goal is to maintain security and avoid unintended keystrokes without causing frustration or technical difficulties.


  1. Can I lock my keyboard without locking my computer screen?
    Yes, there are several ways to lock just your keyboard, such as using third-party software like Keyboard Locker or enabling a physical keyboard lock.

  2. Is there a quick shortcut to lock my keyboard on Windows?
    While there is no default quick shortcut to lock the keyboard alone, pressing Windows key + L will lock your entire computer, keyboard included.

  3. Will locking my keyboard through the Device Manager make it hard to unlock again?
    Disabling your keyboard in Device Manager will require you to access your computer with a mouse and navigate back to the Device Manager to re-enable it. It shouldn’t be difficult, but it requires several steps.

Remember that keeping your keyboard secure when not in use can prevent a lot of potential issues. So, take a few minutes to find the keyboard locking method that works best for you, ensuring each computer break is as worry-free as possible.
