There are many types of locks and they apply to different cases, although it is that class of elements that we do not always know adequately, making it difficult to know which is the ideal lock for a certain space or the one that best suits the needs we have in-house.

However, the security and privacy of our home fall on locks, which is why it is worth learning more about them, analyzing the different alternatives that exist, and understanding in which cases they work best. In this way, we will have a clearer idea of which lock to choose.

Types of home locks that you need to know

Let's review some of the main locks that we can find and which ones can best fit home, office, or even a warehouse.


1. Trigger locks

They are ideal to put them at the entrance of an apartment, not only because they have an aesthetic and elegance that stands out, but because they offer a very good level of security.

In addition to that, they almost always have hidden screws (which improves aesthetics), have reversible folding, and are locks for doors made of wood, aluminum, and wrought iron, among other varieties of materials.

The San Clemente Kwikset trigger provides all the security and elegance mentioned. It has a single-cylinder deadbolt, adjustable latch, can be fitted to both left and right doors, and can be locked and opened.

Its protection system is worth highlighting, as it has Smartkey Security to configure the lock in 3 steps. Likewise, it has ANSI/BHMA first-grade certification. As we can see, security will not be a problem with this piece.

It is made of zinc and steel, with a satin nickel finish, and its dimensions are 24.6 x 7.1 x 21 cm.


2. Knob locks

It is common to find these inside homes, on the doors of rooms, bathrooms, or closets, but they are also used for main doors.

They are also called "cylinders", and consist of two knobs joined by an axis, which is precisely cylindrical and goes through the door from side to side.

The key is inserted in the part that remains on the outside, although there are knobs that do not need it (these are exclusively for interiors).

One option to consider is the Defiant ball knob lock. It has a design that allows the use of a key on the outside and a safe on the inside.

Its security system consists of an adjustable latch of 60 and 70 mm, and ANSI grade 3. It is made of metal and its finish is stainless steel. Its total dimensions are 7.5 x 8 cm, and its versatility allows it to be used as an interior lock or for exterior doors.


3. Smart security locks

Technology has reached these elements, innovating them by offering electronic systems focused on security, to achieve the transformation towards a smart home.

Depending on the subtype of these locks, we can find those that work with a physical keyboard, touch screen, or even via Bluetooth and wifi, the latter being able to connect with a smartphone.

Let's look at some interesting options for smart security locks:

  • Kwikset 275 Electronic Deadbolt – Features touch screen, one-touch locking capability, up to 30 code capacity, alarm, and self-closing motor.
  • Kwikset smart electronic lock with handle: it has a physical keyboard, Smartkey Security system, BHMA AAA certification, reversible lever to be able to put it on right or left doors, and 9-volt battery.
  • Deadbolt Smart Lock: It is a Lockly encryption Bluetooth deadbolt that locks and unlocks wirelessly. It has a fast and precise 3D fingerprint sensor, automatic lock, timer, and PIN Genie technology so that the screen changes the order of the digits before people outside the home.


4. Handle locks

They are basically like knob locks, but instead of having a knob, they are powered by a small crank. For this reason, they are also widely used both outdoors and indoors, and their elegant and modern style makes them very useful for office environments, coupled with their ease of use.

There are key and keyless, options that can be considered:

Brunei Entry Handle (Keyed): ANSI Grade 3 certified, 2-3/4" to adjust latch, corrosion resistant, and keyed pair.

Manhattan Defiant handle for bathroom or bedroom (without key): it has comfortable handles, and the one that goes inside has a lock. It has an adjustable latch of 6 or 7 cm. It is made of steel, brass, and iron, with polished and satin nickel finishes, and ANSI grade 3 certification.

5. Locks for wooden doors, mortise

These types of locks are used inside the doors and can go alone or be complemented with another lock.

They are also known as "embedded" since what is seen is only the hole where the key goes. The interior is controlled by a crank and the exterior works with the aforementioned key.

They fit perfectly on wooden doors, but they are also a good option for metal doors.

A great example of this type of lock is the Bronx Defiant, which works with a double deadbolt and ANSI grade 3 or residential quality. It has a structure with a safe composed of 3 bars, and its manufacture is in brass with satin nickel in its finish. Its dimensions are 24 x 16 x 8.6 cm.

6. Rim locks

They are placed on the inside and, as they are designed for thin construction doors, they remain visible. They are also common alternatives, and that is why more robust models have been developed.

For example, the electromechanical Phillips lock, which adapts to right or left doors. Its design allows a simple inversion in the latch, for doors that open from a distance, exterior or interior.

The strike can be opened with a single pulse, which keeps it open until the door is closed. It can be adapted to systems with intercoms, and it is perfect for doors with a thickness between 35 and 45 mm. In addition, it has protection against picking and has a Y-55 key for 5 bolts in the event of a power outage.

7. Bar locks

They are classic and lately, they are used as complementary options to a lock like the ones mentioned above. They are also known as “security locks”, and having one of these increases that factor significantly.

Much of their popularity lies in the button they have to be able to activate, which gives users greater confidence. The Phillips 800 fixed right bar lock is made of resistant metal, its bar is 7.8 cm, and its mechanism can be free or fixed. In addition, it has a steel bolt, with 5 bolts, against picking. This locking model is also available in a left version.

With all of the above, we now have a better idea of the different types of locks that exist on the market, what their main characteristics are, and what we should consider when installing them in different spaces in the home.
