  • Confirm any prompts.

To re-enable, repeat these steps and choose Enable device.

Using Third-Party Software to Lock the Keyboard

When built-in options are unavailable or inconvenient, third-party software provides customizable and user-friendly solutions for locking the laptop keyboard. These tools often allow temporary lock with easy unlock via hotkeys or password protection.

Popular software options include:

  • KeyFreeze: Locks the keyboard and mouse input, preventing accidental keystrokes.
  • KidKeyLock: Allows locking of specific keys or the entire keyboard with password protection.
  • KeyboardLock: Simple tool that disables keyboard input until a predefined key combination is pressed.

Before installing third-party programs, ensure they come from reputable sources to avoid security risks.

Locking the Keyboard on macOS

macOS does not offer a direct system option to lock the internal keyboard. However, several workarounds exist:

  • Using third-party apps like KeyboardCleanTool allows users to temporarily disable the keyboard for cleaning or preventing input.
  • Employing Accessibility Options such as enabling Mouse Keys can indirectly reduce keyboard use.
  • Utilizing scripting tools (e.g., AppleScript or Automator) to disable keyboard inputs, though this requires advanced knowledge.

It is advisable to keep an external keyboard connected to regain control easily when the internal keyboard is disabled.
