13 Different Types of Door Locks

Types of Door Locks

When considering buying locks for your home or business, the number of choices can certainly be overwhelming. There are many distinct types of locks and many different security aspects to think about before buying it. This webpage will explain the various kinds of locks and the security aspects which need to be analyzed.

Although there are many forms of locks, the four most common are padlocks, deadbolts, knob locks, and levers.


Padlocks will be the sole type of lock that’s usually not permanently attached to anything else. Padlocks come in a selection of sizes, are free-standing & portable, and are one of the most easily identifiable locks. Padlocks are available in two main types of varieties: combination and keyed. Combination locks have one or more variety dials that open the lock once the correct combination is entered. Keyed padlocks have several options to take into account. You will find rekey able and non-rekey able padlocks.


Deadbolts are generally installed outside of the doors and have a few more options to consider than padlocks. Deadbolts have come in three main types: single, double, and lockable thumb-turn. Single-cylinder deadbolts are generally found in most American houses. They utilize a key cylinder on the outside and a thumb-turn (rosary) on the interior to close/open the lock. All these deadbolts have one primary weakness. A double cylinder deadbolt employs a key cylinder on the inside and the outside of the doorway to solve this matter. These have the clear disadvantage of always needing a key to open the door from the interior if it’s locked. The last type of deadbolt is a hybrid between a single and a dual deadbolt and is referred to as a lockable thumb-turn. It sports a thumb-turn on the inside that functions as a typical single cylinder deadbolt, but that the thumb-turn can be secured using a key so that it can’t unlock or lock the doorway.

Knob Locks

Knob locks are often installed in residential scenarios on outside doors in addition to deadbolts and are sometimes used as the chief source of safety for doors. First and foremost, it should be stated that knob locks should virtually never be utilized for safety on external doors. The problem lies in how the lock cylinder is at the knob itself and not the doorway. Almost in every setup, they may be broken off the door with a hammer or bypassed using pliers or a wrench in the back of the knob, absolutely bypassing the locking cylinder.

Lever Handle Locks

Lever managed locks are often used for inner doors in commercial settings. They are easier to open than knob locks since they have a large push-down style handle rather than a knob that someone must grip and turn. Often when disability accessibility is important lever locks are used. Lever handle locks are ADA accessible and that can be changed between left and right-handedness. When buying it is essential to evaluate the proper backset.

Cam Locks

Cam locks are employed in a variety of programs but are most often utilized in filing cabinets, mailboxes, and lower security OEM applications. They are available in many distinct lengths and can use various tailpieces or even”cams” to port with a different locking mechanism. There is a very large assortment of cam options, and we recommend you to see our Cams/Tailpieces webpage. They can rotate clockwise or counter-clockwise with the amount of rotation 90 or 180 degrees.

Rim/Mortise Locks

Rim cylinder & Mortise cylinder locks are generally located on commercial doors, entry glass doors, plus a few apartment doors. While rim locks are very like to mortise locks (many of our Abloy locks have been rim/mortise combo locks) the actual hardware they are used on greatly disagrees. Rim cylinder locks are usually utilized in rim latch locks that are mounted onto the inside of the door. Rim cylinder locks always have a very long metal piece extending out the back of the lock that runs through the door into a locking mechanism on the opposite side of the doorway. Rim locks have been held in place by two screws in the interior that screw into the rear of the border cylinder.

Euro Profile Cylinders

Euro profile cylinders (occasionally called DIN cylinders) are frequently used in locking devices in Europe and other areas of the planet. They’re also utilized in North America in a few sliding glass door locks and room dividing doors. They come in several forms: single cylinder (one-sided), dual cylinder (locking cylinder on each side), and also single-cylinder with thumb-turn (locking cylinder on one side and a thumb turn on another).

Wall Mounted Locks

These locks are mounted in the wall. The most common type of wall-mounted lock would be the Knox-Box or fireman’s box design lock found in many larger businesses as emergency entry into the building’s keys. Wall-mounted locks may be used for much more than simply storage. Some act as little safes or thing residue. Installation is usually done at the time of construction although some wall-mounted locks can be simply installed into existing buildings. Most wall lock may be mounted in many different wall surfaces. Often wall locks will be mounted using an alarm or covers sensors to allow networking into the building’s safety system (to discover unauthorized access). 

Interchangeable Centre (IC) Cylinders

Interchangeable Core Cylinders are often used in larger institutions and companies and are famous for their easy capability to re-key the lock by swapping out the centre without taking the lock apart. I/C Locks have two kinds of keys that work in the lock, the conventional operator key locks & unlock the lock just like ordinary, while the control key, when used, pulls the whole heart of the lockout without eliminating any screws. This is very useful when upgrading locks since the door hardware could be left alone.

Furniture Locks

This category of locks covers a variety of locks such as the cupboard, desk, and sliding door locks. There are two primary styles of furniture lock, bolt design, and push-button style. Bolt design furniture locks have a piece of flat metal that extends outside the side of the lock to secure the device. Frequently, bolt style locks are observed on desks, cabinets, and drawers, and though they’re also used in a huge variety of devices. Push-button design locks have a pole that comes from the rear of the lock which is used to fasten things in place.

Vending/T-Handle locks

These locks are mainly observed in vending machines and T-Handle locks, although they are sometimes used in other applications. T-Handles are frequently unusually simple to substitute as when you start the device you’re pulling the t-handle lockout.

Rim Latch Locks

A rim latch lock has a standard or custom rim cylinder on one side along with a surface mount latch lock on the opposite. Rim latch locks can auto-lock the door behind you and so are popular in certain apartment complexes. Rim latch locks are normally not supposed to require a huge amount of force but can be paired with other locks when used on an outside door.

Key In Knob (KIK) cylinders

Key in Knob cylinder is generally found at the heart of most knobs, levers, and lower cost deadbolts. They are also well known in a type of OEM applications as well as some sliding glass doors. A KIK cylinder is usually hidden inside of the lock with only the circular surface of the lock being visible. Important manufacturers generally have at least one of their designs for a KIK cylinder. Other manufacturers sometimes duplicate the design so that their cylinders can replace those produced by other manufacturers.
