Who am I ? / Key

Who am I ?
Who am I ?

I would like to suggest the key with a hole of a specific place shape, which is correspondent to the key, such as a house, a safe, an office. With these keys, we could distinguish them by touching with our fingers or seeing the shape of holes more easily and quickly.
We would not need to put each key into a door hole to check if it is the key to the place anymore. What is more, it would be a benefit to old and blind people from wasting their time figuring out them and being annoyed. We would be able to recognize them intuitionally.
