How does a disk detainer lock work

Our world is full of dangers and risks, so it's essential to do everything possible to avoid them. One of the first places you'll need to provide the best protection is your house. Thankfully, today there are so many ways to maximize your home security, from all kinds of sensors and detectors to full-scale security systems.

One of the first things to care about is the locks you choose. There are so many different lock types out on the market for all kinds of purposes. All of us are probably familiar with deadbolt locks, smart locks, knob locks, etc. However, do you know anything about disk detainer locks? Today we want to talk more about this lock type and its working principles. We'll define the main features of a disk detainer lock to help you understand if it's suitable for you.

What is a disk detainer lock

A disk detainer lock is not as widely used as other lock types. So, many people might not know what it is exactly.
The main elements of this lock are disks that are operated with the key directly. All these disks have gates of two types – true gates and false gates. A true gate creates a dent, the main purpose of which is to fit in the sidebar. When the sidebar gets into that gap, the plug can turn and the lock will unlock. Basically, the sidebar blocks the movement of the locking mechanism in case the wrong key is used. A false gate is designed to protect the lock from getting picked. Another part of a disk detainer lock is the spacers, which are gaps between the discs.

How does it work

How exactly do these disk detainer locks work? Just like with any other lock type, there are various versions of a disc detainer. These locks can be of different complexity. However, their working principles are pretty much the same.
When you're using the correct key, it'll go all the way through the cylinder, through all the discs. When you rotate the key, all the discs get in a plate and all the true gates form a gap. Then the sidebar gets into that gap and opens the way for the plug. This plug starts turning and other elements of the lock get released. As a result, your door will get unlocked.
