When looking at purchasing door 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.


Padlocks are the only type of lock that is typically not permanently attached to anything else. Padlocks come in a range of sizes, are freestanding 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 Door Locks 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. If a padlock is non-rekeyable, then you cannot change the key that opens the lock (for example to make it use the same key as your house). Padlocks can be key-retaining or non-key-retaining. A key-retaining padlock does not allow the key to be removed abus Padlockwhile the padlock is open. Finally, padlocks can have a shrouded shackle. This is an extension of the body where the shoulders of the padlock raise up the sides of the shackle to make it far harder for bolt cutters to cut the padlock.


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 thumb turn. Single cylinder deadbolts are found on most American homes. They use a key cylinder on the outside and a thumb turn (rosary) on the inside to open or close the lock. These deadbolts have one primary weakness. If access to the inside is possible (via a nearby window or even through the peephole using simple tools), the door can be opened using the thumb turn. A double cylinder deadbolt uses a key cylinder on the inside and the outside of the door to solve this issue. These have the clear disadvantage of always requiring a key to open the door from the inside if it is locked. This can pose a significant problem in a fire or other emergency situation. If used in a residential situation, it is strongly recommended that a key is left on the inside when people are present to ensure a safe exit in an emergency. The final type of deadbolt is a hybrid between a single and a double deadbolt, and is called a lockable thumb turn. It features a thumb turn on the inside that works like a normal single cylinder deadbolt, except the thumb turn can be locked using a key so it cannot lock or unlock the door. This means in a residential situation, the thumb turn can be left in an unlocked position while people are inside the house, and the door locks operate exactly like a standard single cylinder deadbolt. When everyone is leaving, especially for extended periods of time, the thumb turn can be easily locked so that even if someone has access to the door locks from the inside, the deadbolt cannot be unlocked. This type of deadbolt provides maximum flexibility and security in most situations. All deadbolts that we sell are rekeyable, however, products from some vendors are easier to rekey than others

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 as the Door Locks. Knob LockFirst 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. If you currently have knob locks, consider replacing them with simple passage knobs as it will provide almost as much security as long as you are using deadbolts on the same doors. When purchasing complete knob setups it is important to ensure the proper handedness and backset.

Lever Locks

Lever handle locks are frequently used for inner doors in commercial settings. They are easier to open than knob locks as they have a large push down style handle rather than a knob that one must grasp and turn. Frequently when handicap accessibility door locks is important lever locks are used. Our lever handle locks are ADA accessible and can be changed between left and right handedness. When purchasing it is important to measure the proper backset Levers can frequently be the target of torque attacks (excessive pressure applied to the handle to try and force the lock). Some levers are "clutch" levers meaning if they are forced they just turn rather than apply pressure to the lock.lever handle lock

Cam Locks

Cam locks are used in a variety of applications but are most frequently found in filing cabinets, mailboxes, and lower security OEM applications. They come in several different lengths and can use a variety of tailpieces or “cams” to interface with another locking mechanism. There is a very large variety of cam options, They can rotate clockwise or counter-clockwise and the amount of rotation can be limited to 90 or 180 degrees.Mail Box locks

Mortise / Rim Cylinders

Rim cylinder and Mortise cylinder door locks are frequently found on commercial doors, entry glass doors, and some apartment doors. While rim locks are very similar to mortise locks (many of our Abloy locks are rim/mortise combo locks) the actual hardware they are used on greatly differs. Rim cylinder locks are generally used in rim latch locks which are mounted on the inside of the door. Rim cylinder locks always have a long metal piece extending out the rear of the lock that runs through the door into a locking Rim cylinder and Mortise Cylindermechanism on the opposite side of the door. Rim locks are held in place by two screws from the inside that screw into the back of the rim cylinder. By contrast, mortise cylinder locks are threaded and actually screw into mortise hardware that is mounted within the door. They are held in place by a set screw and utilize a cam to actuate the locking hardware. Mortise cylinders come in several different lengths and there is a large variety of options for the cams depending on the exact mortise hardware they are being used for as door locks.

IC Core / Interchangeable Core

Interchangeable Core Cylinders are frequently used in larger institutions and businesses and are known for their easy ability to rekey the lock by swapping out the core without taking the lock apart. I/C Locks have two types of keys that work in the lock, the standard operator key locks and unlocks the door locks like normal, while the control key, when used, pulls the entire core of the lock out without removing any screws. This is very useful when upgrading locks since the door hardware can be left alone. Just the lock cores are replaced with new ones allowing the door to be upgraded in seconds. The most populaIC core for a Commercial door lockr I/C Lock brands are Best, Yale, and Schlage. Their figure-eight style cores are well known and are found in many places around the world. There are different I/C lock formats with the two most popular being Small Format Interchangeable Core and Large Format Interchangeable Core. It is important to note that I/C cylinders can only be installed in housings specially meant for I/C cylinders. They cannot be installed in standard deadbolts or locks not meant to take an I/C cylinder. In almost all cases if your lock can take an IC cylinder you will see the figure eight on the outside of the lock.

Jimmy Proof Deadbolt

Jimmy proof deadbolts are a surface mount product frequently found on apartments and double doors.Deadbolt lock They are sometimes preferred due to the minimal door modifications required. They are also unique as the deadbolt interlocks with the jamb bracket preventing it from being simply pulled apart or forced easily from the outside. A surface mount lock means the lock screws into the inside of the door rather than having a complex drill pattern like a standard deadbolt. Jimmy proof deadbolts only require a hole drilled straight through the door for the rim cylinder. If you have an existing Jimmy proof deadbolt you can generally replace just the Cylinder to upgrade your security.

Panic Bar Hardware

unnamed (7) Panic Bars are a device that's been UL tested and listed. They are meant to be a device that can be touched or hit with any part of your body to actuate the locking device to open and release so you can push the door open. In other words handicap accessible. In some cases these devices have a built in local alarm to announce when somebody exits through these doors. Also they usually can be operated with a key in a cylinder in the outside of the door. for easy entry.
