Smart Key / Key

When we are in dark, we can’t classify things well. Especially, key ring has two or three keys on it. So, I put the light on the head of it to find easily at night. If you press this light button, LED light is available, so you can recognize it visually and you can also recognize where the key can work by voice recognition. Ring on the button is in OFF, the key doesn’t work, even if it is pushed. This ON/OFF button is stick out, so it is can be easily found by your own feeling of hand. Not only ordinary people can use this “Smart key”, but also disabled people especially people who are visual handicapped.
