Types of lock cores


Locks are like silent superheroes. They protect our homes, our cars, and our treasures. But what makes them work? The answer lies in the heart of the lock, a part called the ‘lock core’. Let’s explore five types of lock cores that keep our world secure.


Pin Tumbler Lock Cores 

Imagine a lock as a puzzle, and the key is the missing piece. That’s how a pin tumbler lock core works. It has a series of pins inside. When you insert the correct key, it lifts the pins to just the right height. This allows the lock to turn and open. Without the right key, the pins block the lock’s movement. This type of lock core is very common and is often used in door locks.

Disc Tumbler Lock Cores 

Picture a solar system with planets rotating around the sun. That’s similar to how a disc tumbler lock core works. It has a series of rotating discs, each with a slot cut into it. When you insert the correct key, the slots line up, forming a pathway for the lock to open. It’s a neat design that offers good security.


Sidebar Lock Cores 

Imagine a lock with a double-check system. That’s what a sidebar lock core is. It has an extra locking mechanism called a sidebar. When you insert the correct key, it not only aligns the pins or wafers but also retracts the sidebar. This gives an extra layer of security, making these locks harder to pick.


Tubular Lock Cores

Finally, think about a lock with a circular design. That’s a tubular lock core. It has a circular keyway and keys. The pins are arranged in a circular pattern, and the key is tubular. These locks are often found on bike locks and vending machines.
