How to lock your keyboard without unplugging it
If you want to lock your keyboard for a few minutes, Windows gives you poor options. Win+L locks the session, but the sign-in screen still takes every key you press. Turning the keyboard off in Device Manager works, yet you then need a working keyboard to find your way back, and a laptop's built-in one cannot simply be unplugged.
Keyboard Disabler is a single button. Once Lock the keyboard is pressed, nothing you type reaches any program: not the browser, not a game, not a password field. The keyboard drawn in the window turns dark so you can see at a glance that the lock took. Press Unlock the keyboard and every key is live again.
The pointer is never locked. Because the mouse keeps moving and clicking, the unlock button is always one click away, which is the point of doing this in software rather than pulling a cable.
Lock the keyboard for cleaning
Wiping a keyboard with the PC on usually means a burst of random letters, a few opened windows and maybe a shortcut you did not want. Pick a countdown first, then lock: the chips under the button read Never, 30 sec, 1 min, 5 min and 15 min. The remaining time is shown across the darkened board, and when it hits zero the keyboard comes back on its own.
Five minutes is usually plenty for a cloth and some compressed air, and you never have to reach for a key you have just cleaned to undo anything.
A keyboard lock for kids, pets and shared desks
A toddler watching a video, a cat that chooses the warmest spot in the room, or a display machine left running in public: each one is an accidental keypress waiting to happen. Lock the keyboard and the film keeps playing while the keys do nothing.
For a PC that should come up locked, turn on Start with Windows and "Lock the keyboard as soon as the app opens" in Settings. The tray icon toggles the lock with the window hidden.
Three exits from a locked keyboard, all live together
Any tool that blocks the whole keyboard has to make getting out of it certain. This one never relies on a single exit.
- Escape pressed five times in quick succession, wherever focus is. No setting removes it.
- Your own combination, set under "Lock and unlock with". It starts as Ctrl+F9, and the lock deliberately passes that one chord.
- The countdown, if you chose one, plus the on-screen Unlock button, which the mouse can always reach.
Can you disable just the laptop keyboard?
Not with this app, and it is better to know before you rely on it. Windows hands keys from every attached keyboard down one shared path without saying which device sent them, so the lock applies to the built-in keyboard and any plugged-in one alike. If your goal is to type on an external keyboard while ignoring the laptop's own, this is the wrong tool; if your goal is no keyboard input at all for a while, it is exactly the right one.
