We design a new form of the key and the door lock. Every key has its own shape and its own lock. When you cannot find the keyhole, you can just search the notch on the lock with the key and put it into the notch. Then push the slider on the key, and the key will slip into the keyhole easily.

The shapes of the keys are all different, so people can recognize which key they want just by touching the key. This design is good for the people who cannot see clearly like visually impaired people or elders.
