About 2 million residences are broken into each year. Given this fact, the importance of door locks cannot be overstated. They provide extra security and safety to your home and your family. That’s why you need to pick the best out there. 

There are hundreds of door locks in the market. Choosing the one which works the best is important. In this guide, we are going to talk about the five types of door locks and how to install them. This is particularly helpful for those who want to install a new lock in their home. 

  1. Padlocks

Padlocks are portable locks that belong to the free-standing lock group. They are not attached permanently to the door, and they are easy to recognize due to their looped-handle shackle shape. The great thing about padlocks is they have a shouldered shackle. This part of the padlock shoulder raises the sides of the shackle to inhibit bolt cutters from cutting through it. 

There are two main categories for padlocks: keyed and combination. Keyed padlocks are also available in different subtypes, like keyed alike, keyed differently, and keyable. 

  1. Deadbolt Lock Types

Deadbolts are a type of lock that offers the best protection against burglaries or break-ins. These locks have a unique locking mechanism that resists physical attacks, battering, and boring. The bolts are moved by turning a knob or key without the use of a spring. No one can open it with a knife or hand tool. 

There are two types of deadbolt locks: single and double. Single deadbolts are the simplest ones, and you can activate them via a key. A double deadbolt uses two keys from both sides, while a single, double and lockable thumb turn deadbolt features a thumb turn inside that can be locked with a key. This latter type of deadbolt provides the greatest flexibility and security.

  1. Knob locks

Knob locks are the most common type of door lock. The lock is cylindrical in shape, and it is located in the knob instead of the door. It is also the chief method of security for most doors. When you do plan to install one, don’t use it on external doors since they can easily be broken into with basic tools, like hammers and wrenches.

  1. Mortise Locks

Mortise locks are powerful locks used on external doors. They are composed of an internal system wherein the locksets can house knobs or levers. They are threaded and utilize mortise components added within the door.   

A box lock is set within the mortise. The mortise lockset is secure thanks to the set of crew and cam, making a locking mechanism. It is available in both heavy-duty and light models. 

  1. Cam Locks

Cam locks are a type of fastener that is almost invisible in fully constructed cabinets. They are cylindrical in shape and situated in the wooden part of a cabinet. A metal tube with a hole in one side helps position the bolt placed inside.
