Door locks are one of the most important aspect in your home’s security. Locks provide security for the whole house as it keeps it safe from intruders. When looking at purchasing locks for your home or business, the amount of options can certainly be overwhelming. There are many different types of locks and several different security factors to consider before purchasing. This page will explain the different types of locks and the security features that should be considered.

 Although there are many types of locks, the four most common are padlocks, deadbolts, knob locks, and levers. For homeowners on the hunt for the best lock to protect their home, the following breakdown will certainly come in handy.

Types of Door Locks You Can Choose From


Deadbolts are generally installed on external doors and have a few more options to consider than padlocks. Deadbolts come in three primary varieties: single, double, and lockable thumbturn. Single cylinder deadbolts are found on most American homes. They use a key cylinder on the outside and a thumbturn (rosary) on the inside to open or close the lock. These deadbolts have one primary weakness.


Padlocks come in a variety of sizes, they are free standing and portable, and are one of the most easily recognizable types of lock. Padlocks come in two main varieties: combination and keyed. Combination locks have one or more number dials that open the lock when the correct combination is entered. They are often easy to decode or shim open. Keyed padlocks have several options to consider. There are rekeyable and non-rekeyable padlocks.

Knob Locks

Knob locks are frequently installed in residential situations on exterior doors in addition to deadbolts, and are sometimes used as the primary source of security for doors. First and foremost, it should be said that knob locks should virtually never be used for security on external doors. The problem lies in the fact that the lock cylinder is in the knob itself and not the door. In almost all setups, they can be broken off the door with a hammer or bypassed using pliers or a wrench behind the knob, completely bypassing the locking cylinder.
