It would bring a lot of troubles that we often forget whether the door have been locked or not or how to rotate key to open the door, especially for the OCD persons and the elder. Now a new key with a LCD screen in the end of ordinary key could easily solve this problem. The LCD has seven numbers,which is clockwise to increase. The numbers represent that door is locked how many steps. “-3/3” expresses the door is locked three steps, “0” indicates the door is opened. The“+/-”separately shows that the key is suit for different types of door. When you are outdoors, you can know the door’s state by the number.
