Storage of keys

  I wonder if you can't find your keys when you leave the house? It happens a lot in my family anyway. Either you can't find the keys, or there are a lot of keys, useful, useless, mixed up. It is troublesome to organize and store the key, but if it is stored in a scientific and orderly way, it can make it cleaner and easier to find the key you need.
  Find all the keys in your room, your car, your office, put them together, and set them up. It's best to be careful and find out all of them so you can put them away at once and not have a few more keys pop up later.
