Although the ancient Greeks found a very reliable lock abroad, it was difficult to improve in ordinary families because the key was large and had to be carried on the shoulders. The ancient Indians made another bird-shaped 'mystery lockThe bulge of modern locks was the 'welded fishing lock' invented by the British in the 18th century. The pinball lock we currently use is invented in 1860 by the American Nilus Yale Jr. The invention of the key was later than that of the lock. The ancient Egyptians were the first to use keys in the world. Their lock is to insert a wooden door bolt into a slot, and there is a wooden bolt on the top of the slot. After the door bolt is pierced into the groove, the wooden bolt will pierce into the hole of the door bolt. In this way, the door bolt is very strong, and it is necessary to use the key to open it.

  Because the Egyptian lock can only be used on the side with the door bolt, it is unfortunate that it can be opened and closed flexibly, so on this basis, the Greeks have discussed A lock that can be opened from the other side. The key made by the Greeks was a crooked wooden stick with a shape and size that resembled a small sickle used by a peasant. However, some keys are 3 feet long and must be carried on their shoulders to move and transfer them, which is quite heavy. The Romans can be said to be the most sophisticated locksmiths in ancient times. They have studied the standards for making keys. They have learned how to cut the nails at the end of keys into various shapes.

When primitive people lived in caves, for safety, they sometimes had to push huge rocks to cover the entrance of the cave. It was not a thief but a beast. After the emergence of private ownership, the thief appeared, and the lock was born. As far back as three thousand years ago, China had locks. However, the earliest locks had no mechanism. They were just made into the appearance of ferocious animals such as mountain monarchs. They wanted to scare the thief away. It could only be said to be a kind of meaningful lock. I heard that Lu Ban was the first person to install a mechanism on the lock. Judging from the situation reflected in the unearthed cultural relics and written records, the ancient lock was based on the elastic force of two plate springs. Until now, this spring is still in use.
