How Many Locks Types Do We Have

The first known lock was made approximately 4000 years ago in ancient Assyria. If this is correct then we can assume this date as a starting point. Through the years there have probably been hundreds or even thousands of lock types throughout history. Some of those locks proved to be rather useless and some of them were replaced by more technologically advanced ones as the years went by. However, at some point, they were cutting-edge technology and provided people's homes with the highest possible level of security for those times. They were also the source of all of today's modern locks.
Let’s quickly explore the most popular door lock types. We have excluded the ancient lock types because they are no longer in use.


Padlocks are one of the most frequently used types of locks. Its popularity depends on its portability. When you don't need to lock one facility or some item anymore, you can use your padlock for securing something else. The technology is quite simple, which is another reason why padlocks are so widely used. A padlock consists of two main elements - the shackle and solid padlock body. The last one can be of two types. A key-based padlock is a classic lock and spares you from remembering a combination. A combination padlock is more modern and spares you from carrying around a key. Generally speaking, both of them work similarly and are secure, but still, more people prefer time-tested key-based padlocks.

Once you turn the key, the cam (the metallic element of rectangular shape) rotates to 90 or 180 degrees and prevents the door from opening.

Digital Locks

These locks are commonly used for hotel rooms. However, not surprisingly, they have recently started to win the hearts of average homeowners. Easy to use and easy to rekey, they became an excellent alternative to classic locks. Also, since there's no keyhole and no physical key, they can't be picked. You open this lock using a swipe card or a pin code.
