The Evolution of Locks. Locks have come a long way since their inception. Here's a brief overview of their evolution:

• Ancient Locks:

The earliest known locks date back to ancient Egypt, using wooden pins to secure doors. Society itself only dates back around 5,000 years, but security has always been a concern. Physical security began as humans and their animals, being present at the areas they needed to protect. But the locks provided them a way to keep the doors closed and limit who can gain access.

• Medieval Advancements:

The introduction of metal and complex mechanisms during the Middle Ages led to more secure designs. There was an interest in the increased security and many tradesmen competed to design the best security products and make them smaller and easier to use.

• Modern Innovations:

Today's locks include electronic and smart technologies,
offering convenience and advanced security features. Modern locks have evolved immensely and the changes are too drastic to list out. Consider the first safes and vaults and their modern-day equivalents, with time locks, 6-sided hardened steel, with time locks and glass-break activated relockers.
