Most of us use locks every day to keep ourselves and our belongings safe, but how much do we know about them?

Here are five fascinating facts about locks that you probably didn’t know:

1. The ancient Egyptians developed the oldest locks thousands of years ago.

2. There are six main lock designs that are commonly used for doors, along with a few others for different purposes.

3. In some parts of the world during the Medieval Era, town guards would hold the keys to homes instead of owners.

1. How old are locks?

Locks have been around for thousands of years. The oldest known lock was found in the ruins of the Palace of Khorsabad in Iraq and dates back to around 704 BC. It was a simple pin tumbler lock made of wood.

2. How do combination locks work?

Combination locks use a series of numbers or letters to open the lock instead of a physical key. The lock has a dial or keypad that you turn or press to enter the correct combination. When the correct combination is entered, the lock opens.

3. Are all locks created equal?

No, not all locks are created equal. There are different types of locks for different purposes, and some locks are more secure than others. For example, a padlock is not as secure as a deadbolt lock for a front door.

4. Can locks be picked?

Yes, locks can be picked. Lock picking is the process of manipulating a lock’s components to open it without a key. It’s a skill that can be learned and used for both legal and illegal purposes. However, picking a lock is illegal if you don’t have permission to do so.

5. What is a bump key?

A bump key is a special key that can be used to open many types of locks. It works by inserting the key into the lock and then tapping it with a blunt object, such as a hammer or screwdriver. The force of the impact causes the pins inside the lock to jump, allowing the lock to be turned and opened. Bump keys are often used by locksmiths, but they can also be used by criminals to gain entry to homes and businesses.
