Go Ahead Key – Lock Indicator by Jongoh Lee

We turn the key and lock the door. Through this action, I came up with an idea and created a key which has a center part turning round. This part helps indicate open and close of the door. When we insert the key into the key holder and turn round, by moving Flexible plastic, which indicates close and open, attached to the handle of the key, close state is shown. This structure is very simple and electricity is unnecessary.
