If you have AutoHotkey program installed, use the .ahk file to launch the tool. You can even make some changes to it if needed. Otherwise, simply double-click the executable file to launch it. Once launched, it sents a quick notification and then stays in the system tray waiting for your command.

To lock the keyboard, press Ctrl + Alt + L, as instructed. The Keyboard Locker icon changes accordingly to indicate that the keyboard is now disabled.

When the keyboard is locked, most of the function keys, e.g. Function Keys, Caps Lock, Num Locks, will stop responding. However, other powerful keyboard combinations like Ctrl + Alt + Del or Win + L will still remain functional.

To re-enable the keyboard, type “unlock” on your keyboard. The Keyboard Lock icon changes back, indicating that the keyboard is now unlocked.

The notification is disabled by default. But you can turn it on by right-clicking the Keyboard Lock icon in the system tray and selecting Show tray notifications.
