Kid Key Lock is the small cousin of Pro Key Lock. It is a simple and free utility to lock specific keyboard and mouse functions.

Kid Key Lock (or Kid-Key-Lock, or KidKeyLock) is ideal to be used in order to prevent toddlers from accidentally pressing unwanted buttons on your keyboard and mouse.

When Kid Key Lock is running, an indicator icon will appear on your system tray. When you click on the tray icon a pop-up menu will appear. All program functions, including the setup dialog box are accessible from this menu.
