The Different Types of Locks You Should Know

If you are a homeowner or an apartment owner, you should know about the different types of locks that are available. These locks help secure your home and provide peace of mind. There are several types of door locks, and they differ in appearance and how they work. Knowing which lock is best for your door will help you determine how to install it properly and make sure you choose a quality lock that meets your needs.


A deadbolt lock is a type of lock that prevents your door from being pushed open by force. It consists of a cylinder that is connected to a latch. The cylinder can be actuated by a key on one or both sides and by a lock mechanism that rotates to move the bolt.

Single Cylinder Deadbolt: This is the most common type of deadbolt that needs a key to unlock. It is ideal for doors that do not have breakable glass panels near the thumbpiece turn or that don’t have a large letter plate.

Double Cylinder Deadbolt: This is another popular type that requires a key to unlock. This provides an extra layer of security, especially if there are glass panes near the doorknob.

Barrel Bolts

Barrel bolts are a common door lock that uses a sliding metal bar and a catch plate to secure the door. They are simple to install and come in various styles and finishes. According to a door specialist, these locks are great for boosting the security of any door or cabinet. They can be found in various materials, including brass and stainless steel. They are also available in various sizes, so you can find one that suits your needs perfectly.

Handle sets

Handle sets are an excellent way to make your doors stand out and look more elegant. They come in many styles, finishes, and trim options to choose the best one for your home. These locks often have a deadbolt on the exterior side and a handle that’s operated with your thumb to open the latch. Depending on your model, they are usually paired with a keyed lock on the interior. Two-point locks pair a deadbolt with a knob or lever on a solid, decorative backplate, and there are many different configurations to fit your door’s specific requirements. For example, you can get a square-corner or round-corner backplate. You can even get an emergency egress function that can unlock the deadbolt and lever by pulling on the inside handle.

Hand Levers

Levers are simple machines that convert small forces into large ones. They are important because they often transfer force from one area to another. A lever consists of a rigid bar that can pivot around a fulcrum, which acts as the point where the bar turns. Its efficiency depends on the ratio of its effort arm to its load arm. Different classes of levers are identified by how the joints and muscles attached to the bone are arranged. First-class levers involve a fulcrum that is between the load and the effort (for example, using a seesaw or crowbar). Second-class levers involve a fulcrum located between the load and the resistance. Third-class levers involve a fulcrum where the load and the effort are separated by distance.


Padlocks are portable locks with a shackle that can be passed through an opening to secure things or prevent people from using, damaging or stealing them. They are a popular type of lock and can be found on everything from fences to sheds to toolboxes. To work, a padlock has to have several different parts that all need to fit together correctly. These include a key plug, pins and bits that hold the shackle. These are all put together in factories crafted to ensure that everything is secure and can’t be broken easily by people trying to get into places. They also have multiple layers of protection, which help make them harder to break than other locks.
