Method 4: Disable the Laptop Keyboard on a Mac Using Karabiner-Elements

macOS has no built-in setting to turn off the laptop keyboard. You can do it with a free app called Karabiner-Elements. This method needs an external keyboard connected to the Mac.

Download Karabiner-Elements from its official website and install it.
Open System Settings and go to Privacy & Security.
Allow Karabiner-Elements in Input Monitoring and approve any system extension or background item request.
Connect your external keyboard.
Open Karabiner-Elements and click the Devices tab.
Find your external keyboard in the list.
Turn on Disable the built-in keyboard while this device is connected.

The Mac keyboard stops working while the external keyboard is connected.

To enable it again: Turn off the same option in Karabiner-Elements, or disconnect the external keyboard.

Conclusion

You can disable a laptop keyboard in just a few minutes. On Windows, use Device Manager for a quick, temporary fix, Command Prompt for a lasting one, or Group Policy Editor on Pro, Enterprise, and Education editions. On a Mac, use Karabiner-Elements with an external keyboard connected. Every method can be undone, so you can turn your laptop keyboard back on whenever you need it.
