Many people are sometimes forgetful such as forget to bring keys or cell phone. This situation often occurs on the old people. As such a key box is designed to solve this problem. The designed key box can set up time to make some sounds and the lateral side will give out light if something is left in the box. Both functions of the key box will remind people to pick up the essential things when going outside.
