The Different Types of Door Locks: A Comprehensive Guide

Door locks are an essential aspect of home security, as they provide a physical barrier that helps to keep intruders out and your family safe. There are a wide variety of door locks available on the market, each with their own unique features and advantages. In this article, we will provide a comprehensive guide to the different types of door locks that are available, including the most common types and their uses.


  1. Deadbolts are one of the most common types of door locks and are known for their high level of security. They typically consist of a metal bolt that extends into the door frame when locked, making it extremely difficult for intruders to force the door open. Deadbolts are available in single- and double-cylinder models. Single-cylinder deadbolts have a keyed cylinder on the exterior and a thumb turn on the interior, while double-cylinder deadbolts have a keyed cylinder on both the interior and exterior.

Knob locks

2. Knob locks are a common type of lock that are typically used on interior doors. They consist of a door knob that is turned to engage or disengage the lock mechanism. Knob locks are not considered as secure as deadbolts, as they can be easily picked or pried open. However, they are a popular choice for interior doors due to their ease of use and classic design.

Lever handle locks

3. Lever handle locks are similar to knob locks in that they are typically used on interior doors. They consist of a lever handle that is turned to engage or disengage the lock mechanism. Lever handle locks can be more secure than knob locks as they are more difficult to pick, but they are still less secure than a deadbolt.

Mortise locks

4. Mortise locks are another type of lock that is commonly used on exterior doors. They are known for their high level of security and typically consist of a metal case that is installed into the door. The lock mechanism is contained within the case and is operated by a key or thumb turn. Mortise locks are considered more secure than other types of locks, as they are more difficult to pick or force open.

Smart locks

5. Smart locks are a newer type of door lock that can be controlled and monitored via a smartphone app. They typically consist of a deadbolt or latch mechanism that can be locked or unlocked remotely, and can also be set to automatically lock or unlock at certain times. Smart locks also have the ability to grant temporary or permanent access to specific individuals, and can send notifications when the lock is used. This type of lock is also usually integrated with other home-automation devices.

Keyless entry locks

6. Keyless entry locks are another newer type of door lock that do not require the use of a key. Instead, they use a code or a biometric feature such as a fingerprint or facial recognition to grant access. They are becoming more and more popular as a means of home security. Some keyless entry locks are even integrated with a smart home system, allowing you to control and monitor the lock remotely.

In conclusion, when it comes to door locks, there are many options available, each with their own set of features and advantages. Deadbolts are the most secure, while knob and lever handle locks are less secure but more convenient. Mortise locks are a great option for exterior doors, while smart locks and keyless entry locks offer added convenience and security features. Ultimately, the type of lock you choose will depend on your specific needs and preferences. When it comes to home security, it is recommended to consult with professional locksmith to choose the most suitable type of lock for your needs.
