There are several main types of door locks commonly used for residential and commercial purposes. Below, we have listed a few of the frequently encountered types.

Deadbolt Door Locks:

Deadbolts are considered one of the most secure types of locks. They have a solid metal bolt that extends into the door jamb, providing added strength and resistance against forced entry. Deadbolts can be single-cylinder (operated with a key from the outside and a thumbturn on the inside) or double-cylinder (requiring a key on both sides).

Knob Door Locks:

Knob locks are commonly found in residential settings. They have a knob on one side of the door and a key cylinder on the other. While knob locks are convenient, they are generally not as secure as deadbolts because the lock cylinder is located within the knob, making it more vulnerable to forced entry.

Lever Handle Door Locks:

Lever handle locks are similar to knob locks but feature a lever instead of a knob. They are often used in commercial buildings and are designed to comply with accessibility requirements. Like knob locks, lever handle locks are generally less secure than deadbolts.

Mortise Door Locks:

Mortise locks are more complex and durable than standard deadbolt locks. They require a pocket (mortise) to be cut into the door and frame to accommodate the lock. Mortise locks usually have a lever handle and offer additional features such as multiple locking points and built-in deadbolts.

Keyless Entry Door Locks:

Keyless entry locks, also known as electronic or digital locks, allow access without using a traditional key. They can be operated through a keypad, touchscreen, or even a smartphone app. Keyless entry locks often offer convenience features such as programmable access codes and remote control access.

Cylinder Door Locks:

Cylinder locks, also called pin tumbler locks, are commonly used in various types of locks, including deadbolts, knob locks, and lever handle locks. They consist of a cylinder with pins of varying lengths that must be aligned by the correct key to open the lock.

These are just a few examples of main door lock types. Each type has its own advantages and considerations, so it’s important to choose a lock that suits your specific needs in terms of security, convenience, and functionality.
