Have a pet who loves to mess with a keyboard like a playground? Actually, they love to write their love story! Aha, by bad.

To be honest, we all are in the same circumstances, or some ignorant who do not belong to computer line, especially kids, love to finger in keyboard button. That’s how I found a tool that can disable/lock the keyboard’s working whenever pressing the shortcut key in series.

Today, you will learn to disable/lock the keyboard for a temporary on both Linux and Windows systems.

Lock Keyboard on Linux using Xtrlock

Xtrlock is a small utility added to all Linux repositories. A default package manager is enough to install this package in all major Linux distributions.


While installation, makes sure to connect with an active internet and update and upgrade your system.

Debian and Ubuntu

$ sudo apt install xtrlock

RHEL and CentOS

$ sudo yum install xtrlock


$ sudo dnf install xtrlock

Arch and Manjaro

$ sudo pacman -S xtrlock

Xtrlock Usage

After installation, type the below command in your terminal to lock your keyboard instantly.

Note: While using xtrlock command without any flag in KDE DE make me hard to unlock my system. For that I repetitively used to click mouse and then type password and press enter to unlock. To avoid doing this, use -f flag to unlock immediately.

$ xtrlock

To unlock immediately, type your root or normal user password.

Attach Keyboard Shortcut to Xtrlock Command

Every time to lock your keyboard, you need to type the xtrlock command in the terminal. To use the shortcut key for that job, follow the below method.

for Gnome Desktop Environment

Open settings ⚙️ from app dash or menu, and navigate to the Keyboard shortcuts tab.

Now Add Custom Shortcut window will appear with two input boxes. Type the name for your shortcut on the first input box and the command to be executed (In this case, xtrlock) on the second input box.

Finally, add a custom shortcut key relevant to you. In my case, I used Ctrl+Alt+L as a shortcut key.

Windows has another utility named keyboard locker, initially started as AutoHotKey script turned into a standalone application. It is a small tool without needing to install the AutoHotKey application in your system.

To get started, first download the Keyboard Locker application. The downloaded file will be in zip format uncompress it with any tool (Ex: 7zip).

To use double-click on the KeyboardLocker.exe, and it will open as a tray application. To lock your keyboard immediately, use the Ctrl+Alt+L shortcut key.

Once you have done, time to unlock your keyboard for that type unlock on your keyboard to release the lock from the keyboard.


Instead of clicking application on every reboot to activate the keyboard locker. You can place all the files inside the startup folder to start the application with the system.

Use the Win+R shortcut key to open the Run window and type shell:startup.
