Benefits of smart locks:

Traditional door locks require you to carry a key, unlike smart locks which offer keyless entry. You might also worry about losing the key and feel insecure. When you’re not home, you might worry about the home security. When your friends come to visit and you’re not home… In these situations, the importance of a smart door lock system becomes apparent.

How to choose the right smart door lock?

 

 

 

Before you begin the installation, it’s crucial to choose a smart lock model that is suitable for your door frame and meets your security and convenience needs. Please consider the following four factors:

 

User Considerations:

When choosing a smart home lock system, it is crucial to carefully assess the characteristics of the user group and their accessibility needs.

In households with elderly individuals or young children, combination keypad locks may pose accessibility challenges due to the need to remember passwords. Similarly, fingerprint locks can be unreliable in recognizing smudged or damaged fingerprints, a situation particularly common among the elderly and manual laborers.

For high-traffic areas such as company offices, multi-unit apartments, or student dormitories, systems offering multiple access methods (e.g., mobile credentials + facial recognition + exterior keypad) should be prioritized. This approach meets the needs of diverse user groups and maintains an audit trail through access logs—essential for locations requiring management of frequent personnel movement or visitor access.

 

Smart lock details:

 

Pay attention to the lock body material, working method, security functions, etc.

Choosing a Class C certified lock cylinder (for longer resistance to technical opening) and a corrosion-resistant metal panel can significantly improve physical integrity and extend the mechanical lifespan of the smart lock.

Modern smart lock solutions typically employ two operating architectures: fully automatic and semi-automatic. Fully automatic locks utilize electromechanical actuators to automatically extend and retract the bolt, significantly improving convenience and user experience. Semi-automatic systems retain the operating door hardware (pressing down or lifting the door hardware) to extend and retract the bolt; however, the need for user operation to open and close the lock poses a security risk of missing doors. Nevertheless, semi-automatic locks offer more stable performance and lower maintenance costs.

Before purchasing, understand the security features of the door lock (abnormal alarm, temporary password, emergency power supply, video surveillance, voice intercom, etc.), and consider the smart lock functions in combination with the ease of operation and access system requirements of the occasion.

Compatibility:

 

Door panel thickness determines lock cylinder size and lock body fit, while lock body size determines door frame alignment parameters. Compatibility between the smart lock, auxiliary latch, and the door material also needs to be considered.

Assess compatibility with existing security systems or smart home systems. For unified access management and synchronized operation, you can choose a compatible ecosystem from the same brand or a centralized software platform that matches your security infrastructure.

 

How to install a smart lock?

 

When purchasing a smart lock, the product packaging usually includes a detailed installation guide and a complete set of locks and accessories. Assess the installer’s skill level and the door’s structural specifications to determine if a perfect installation can be performed independently. The standardized installation process follows this sequence:

Before installation:

Inspect the smart lock components: front panel, back panel, lock cylinder, mortise locks, and auxiliary components (mounting plate, strike plate, washers, battery cover, screws, etc.);

Check the lock for any abnormalities or surface defects, and confirm that the dimensions meet the door specifications;

Prepare installation tools (screwdriver, drill, marker, measuring tape, etc.);

Smart devices (install the necessary remote management smartphone app and network connection equipment).

 

Installation process:

① Install the lock body: Install the lock body onto the door with the pre-drilled hole and secure it with screws;(The direction of the latch can be adjusted according to the door opening method)

② Install the lock cylinder: Insert the lock cylinder into the lock body from the outside, with the key facing outwards and the pivot brass strip facing inwards；

③ Install the front panel: Secure it to the front panel studs with 2 screw sleeves (the locks must not be loose), align the front panel assembly with the holes in the door body, and install it on the outside of the door body；

④ Install the rear base plate: Put the silicone pad into the rear base plate, align the rear base plate with the hole in the door body and install it into the door body. Insert two screws from the base plate and tighten them with the screw sleeve of the front panel assembly.

⑤ Install the rear panel assembly: Insert the square bar into the square shaft of the lock body, and then install the rear panel assembly on the interior door. During installation, the lock cylinder square bar, deadbolt square bar, square bar, and rear bottom plate studs need to be aligned with the corresponding holes before the rear assembly can be locked and fixed.

⑥ Install the battery: Install the battery and put the battery case cover on to complete the installation.

After installation:

Perform an integrity test on the lock to ensure smooth motor rotation and noiseless opening and closing; enter and set the unlocking password, and check its accuracy.

 

 

 

Main types of common smart locks

 

 

 

According to the connection method:

 

Bluetooth: Unlocks via Bluetooth connection to a mobile phone. This is easily limited by distance and signal strength, and usually requires a gateway for remote management.

WiFi: Enables remote management and monitoring via an app. It has high signal requirements and requires the same WiFi and app environment for smart system integration.

Zigbee: A low-power, short-range smart lock, similar to Bluetooth locks, but with lower power consumption and higher cost.

Offline: Simply store unlocking information locally; unlocking is achieved through recognition such as cards, RFID keys, remote control or passwords.

 

 

 

 

 

 

 

According to the unlocking metho

Cards: Smart card systems are based on proximity card technology (mainly RFID/IC cards), with embedded encryption chips. They are linked with access control systems to support multi-level access permissions and real-time auditing functions. They are often used in high-traffic scenarios such as hotels or apartments. Their anti-copying features and dynamic key mechanism effectively enhance control access security.

Biometrics: Uses unique individual physiological characteristics for identity verification, with face, fingerprint, and palm vein as core elements. Commonly used in high-security environments such as homes and government offices, it also provides remote access and real-time monitoring capabilities.

This blog will help you learn more about biometric locks.

Password: The access control system is controlled by preset encryption protocols. Users enter a password on the digital keypad to trigger the circuit or chip to work. After identity verification, the electromechanical transmission device is triggered to unlock the device.

Mechanical key and external power supply: Smart locks typically have a mechanical keyhole and a Type-C emergency charging port. When the electronic system malfunctions or the battery is low, the user can unlock the door using the physical key. It is also compatible with power banks for basic lock functions.
