Unlocking Your Style: Types of Door Locks and Handles

When it comes to modern building security, door locks have become indispensable. Whether it’s your home or a commercial space, door locks are the primary choice for protecting your privacy and property. In this guide, we’ll delve into the realm of door hardware, examining different types of locks and handles, and demonstrating their optimal uses in various situations. Furthermore, we’ll offer you guidance on purchasing to assist you in crafting a secure and appealing environment for your space.

Understand Different Types of Door Locks

1. Knob Lock

A knob lock is a frequently used type of door lock characterized by its straightforward design. In this type of lock, the lock mechanism and the handle are combined, typically in a circular shape. Due to its simple manufacturing process, it’s cost-effective.

However, due to relatively poor security performance, it’s typically not advisable for use on exterior doors. Instead, it’s better suited for interior doors, such as those found in bathroom doors and bedroom doors.

This type of door lock is unlocked by inserting the corresponding key and turning the lock core. Once the correct key is used, you can easily turn the knob to retract the latch from the door frame, completing the opening action. 

2. Cam Lock

Also known as a cam lock or latch lock, it’s a type of locking lever used to secure doors. Its body consists of a metal piece with a cam, attached to the core of the lock, which rotates with the insertion and turning of a mechanical key. When the latch rotates 90 to 180 degrees, it can lock and unlock the door.

This type of lock is relatively simple and typically doesn’t include a handle, so an additional handle is needed. Common uses include lockers, safes, windows, cabinets, filing cabinets, etc.

3. Slide Latch Lock 

A slide latch lock is a simple yet effective security component for doors. It consists of two main parts: a part with a movable bolt and a lock hole mounted on the door frame. Usually, the part with the bolt is fixed to the door, while the lock hole is fixed to the door frame, with their corresponding positions.

When the door is closed, inserting the bolt into the lock hole locks the door; when the door needs to be opened, simply retract the bolt. For extra security, people often combine this deadbolt lock with other types of locks such as padlocks, electronic locks, etc.

Slide latch locks are typically made of a single material, with common colors. Nevertheless, their structure is relatively robust and very easy to use. While more sophisticated anti-theft locks are now prevalent, slide latch locks remain popular choices for securing areas such as public restrooms and warehouse doors.

4. Mortise Lock

A mortise lock is one of the most common door locks, typically consisting of a handle, lock core, and lock body. Due to its larger panel design, a mortise lock can be matched with different types of door handles to accommodate various style preferences. This type of lock is versatile and typically used on interior suite doors and security doors.

Among them, the lock core is the core component of the mortise lock, containing slots and springs. The slot is where you insert the key, and the spring keeps the slot steady. When the correct key is inserted into the mortise lock, the slot rotates to the correct position accordingly. This releases the latch, allowing the door to be opened.

Depending on the internal structure, mortise locks can generally be divided into several types such as single-latch mortise locks, double-latch mortise locks, and single-latch button mortise locks. Each type has its unique structure, performance features, and situations where they are most suitable for use.

5. Padlock

A padlock is a convenient and easy-to-use non-fixed lock, which can be divided into two types: key-controlled and combination.

• Key-controlled padlock: The principle is similar to that of a mortise lock. It consists primarily of a lock core, internal pins, and a corresponding key. When the key is inserted and turned correctly, the pins align to the proper positions, enabling the shackle to unlock and open the padlock.”
• Combination padlock: Typically only includes a rotating dial or button, without a key. Unlocking the device requires only rotating the dial according to the pre-set numerical combination.

Regardless of the type, padlocks rely on hooks on doors or other structures to lock. This type of lock is usually used in situations requiring temporary or portable security solutions, such as door handles, lockers, suitcases, etc.

6. Glass Door Lock

Glass door locks have become essential security devices for today’s popular glass doors. Glass door locks are specifically crafted to work seamlessly with glass doors and offer reliable security for private areas, unlike standard door locks.

They employ various special installation methods suitable for different types of doors, such as tempered glass doors, sliding glass doors, and framed glass doors.

There are various styles of glass door locks, including clamping, magnetic, and key-operated types. Each type has its unique features and security performance. Some come with built-in handles, while others require additional handles.

• Clamping glass door lock: Fixed on the glass door by clamping or pressing. The lock comes with clamps or pressure plates designed to securely attach it to the edge or surface of a glass door, preventing it from being pushed open. This lock can be installed on single-sided or double-sided glass doors, with easy installation and no need for drilling.
• Magnetic glass door lock: Uses magnetic principles to keep the door closed. Typically, magnetic components are installed on the glass door. When the door is closed, these components adhere together to keep the door closed. Common methods for opening doors typically include using keys or magnetic cards. When the card is successfully scanned, the magnetic components of the door are disengaged, allowing the door to be unlocked.
• Mechanical key glass door lock: Standard cylinder lock mechanism. Insert a key into the lock core and rotate it to release the locking mechanism. This type of lock may require special installation to ensure that drilling holes in the glass do not damage or weaken its structure.

7. Smart Door Lock

A smart door lock enhances standard mechanical locks by adding intelligence and convenience to user security, recognition, and management. It can be unlocked using traditional mechanical keys and integrates various advanced unlocking methods such as passwords, fingerprint recognition, facial recognition, and RFID cards.

Many smart locks also support wireless communication technologies such as Wi-Fi, Bluetooth, Z-Wave, or NFC. This allows them to seamlessly integrate with other smart devices (such as smartphones and smart home controllers), providing users with a smarter and more convenient door lock experience.

The smart door lock market offers a diverse range of choices, including different types and styles. Besides enhancing user convenience, they also add a surprise element to architectural spaces, enhancing the overall aesthetic.

Smart door locks are currently the most popular type of electronic door locks on the market. They’re widely utilized in private homes, commercial buildings, offices, and rental properties.

8. Electric Lock

An electric lock is a mechanical locking device operated by a relay. It encompasses various structured products such as electric rim locks, magnetic locks, and electric drop bolt locks.

They each have their characteristics in terms of installation, usage, and application:

• Electric rim lock: Unlocks automatically when the power is cut. Usually controlled by an electric motor or electromagnet, pulling or pushing the bolt to unlock. Suitable for situations requiring quick unlocking, such as emergency evacuation routes or fire doors.
• Magnetic lock: Uses the attraction between an electromagnet and an iron block to close the door, also known as a fail-safe electric lock. The electromagnet is mounted on the door frame, while either an iron core or suction cup is installed on the door itself. A strong magnetic force is generated to secure the door shut when the power is connected. Typically used for wooden doors, fire doors, and glass doors.
• Electric drop bolt lock: A mechanical lock device controlled by a relay, unlocking the door by controlling the current. Provides an extra layer of security, and can be integrated with various access control systems. Suitable for residential homes, commercial buildings, schools, hospitals, etc., providing convenient access control solutions.

In terms of installation, all three lock types need to consider compatibility with door frames and doors, power supply, control system installation, and relevant safety standards and regulatory requirements.

In terms of application, electric plug locks are suitable for situations requiring quick unlocking, magnetic locks for situations requiring forced locking, and electric control locks for situations requiring high security and flexible access control.
