How it works
Lockey sits quietly in your menu bar and intercepts keyboard events at the system level when you need it.
Lockey lives in your macOS menu bar, always one click away — no extra windows or docks needed.
Hit "Lock Keyboard" and Lockey immediately begins suppressing all standard key events at the system level.
Wipe down your keys without worry. Click "Unlock" in the menu to restore full keyboard functionality instantly.
