There are enough circumstances under which we do want our keyboard to be locked. So I’m convinced that we should have a little device to lock our keyboard. Keylock uses a switch to lock and unlock the keyboard. It uses the USB to connect with the laptop. To avoid being charged of wasting a valuable USB dock, it has a USB dock at its back so that other devices could connect to the computer through keylock.
