Lock and key history

Lock and key history

Wooden locks

At first, the locks were very simple; the knots and ropes and other devices were also for when someone tried to open the locks. With time and progress, real-time locking technology was made of wood and metal, and was quickly used throughout the world by people.


New age historians are not sure which ancient civilizations have made mechanical locks for the first time, Egyptians? Romans? Greeks? Perhaps the Iranians; many believe that these civilizations have built their own locks independently of one another.

Mechanical locks

The history of mechanical locks began six thousand years ago in ancient Egypt. Where a locksmith decided to make a simple, but efficient needle lock that was made entirely of wood. The lock was made of a wooden frame to fit perfectly with the doors, and a horizontal bar locked into the frame. It had needles that were suspended. Each lock had a large and unique wooden keys similar to those of today's toothbrushes, with a clamp and grooves that, by inserting it into the lock and in the direction of inserting the needles, raised the permission to shake the security rod and The lock was unlocked.

Metal locks

In the middle of the first millennium BC, locks began to develop with the technology of the Romans and the Greeks. The locks made by the Greeks were simple and insecure, but inspired by Roman innovators who quickly developed the locks made by the Greeks and Egyptians using metal as the primary material. By using iron locks, the Romans could not only protect their devices against heavy attacks, but also could use small keys for the first time and even put them in their pockets. And that was the first generation of keys to turn the lock into the lock.

Ambiguous and complex

After the collapse of the Roman Empire in the first century AD, the development and innovation of locks were completely stopped. Locators in dark and medieval Europe did not have the resources and technology to build a security device, but they used this time to confuse and complicate the way for those who wanted to break the locks. Instead of a simple lock, they made a lock that had the mechanism to open with a few keys, and the key design was more complex every day than yesterday; they locked the locks with certain specifics, and made The key holes were used (with counterfeit mechanisms inside it).
