In recent years, smart locks have become one of the most popular smart home products in the field of smart homes. Numerous lock brands, internet companies, and traditional home appliance companies have invested in the research and development of smart locks. So, what are the necessary tests for a smart lock to be considered a qualified product? The following factors and standards are provided for your reference:

smart lock test 1

A. Security Testing

The key function of a door lock is to protect the security of your personal space. Therefore, security testing is one of the most critical steps before a smart door lock leaves the factory. Evaluating the security of your smart lock should include the following aspects:

  • The encryption algorithm strength testing.

When evaluating the strength of the encryption algorithm used by the smart lock, several key factors should be considered. Identify the encryption standards implemented by the smart lock, such as AES or RSA. And verify the specific encryption protocols and key lengths used. It is also important to evaluate the smart lock’s resistance to password attacks (such as brute force attacks or dictionary attacks).

Furthermore, proper key management is crucial, including secure key generation, distribution, and storage. Regular firmware updates and vulnerability patches ensure continuous protection for your smart door lock system.

  • Physical security testing.

Evaluate the security features of the smart door lock, such as fire resistance and anti-prying capabilities. Fire resistance testing should include continuous burning and gap deformation tests to test the fire resistance integrity of the product. And use cotton pad testing to observe fire resistance performance, and temperature rise testing.

  • Evaluate resistance to common hacking techniques.

Ever since the incident involving the “black box,” whenever smart locks are mentioned, people often ask, “The black box can open smart locks within three seconds” Is that true?

In fact, the black box, also known as the Tesla circle. It affects the internal electronic circuit of the smart door lock by generating high-frequency, high-intensity electromagnetic pulses, causing the door lock to reboot or experience signal interference, thus unlocking it. However, it is not a universal master key in itself.

Currently, many high-quality smart lock manufacturers have upgraded and improved their locks, making them capable of passing the black box test successfully.

B. Performance Testing

This stage should include testing the speed and accuracy of the smart door lock’s unlocking or locking mechanism and the reliability of the lock’s sensor technology for identifying authorized users.

Test the effectiveness of authentication methods such as PIN code unlocking, temporary access code unlocking, fingerprint unlocking, key card unlocking, and mobile phone unlocking. Different smart locks offer different options for unlocking methods.

So tests should be conducted based on the specific unlocking methods provided. Specific testing contents should include response time, sensing distance, fingerprint/password/card capacity, etc. Through testing, issues such as skipping keys or slow responses can be prevented. The faster the unlocking speed and the higher the accuracy, the better the performance of the smart lock.

C. Usability Testing

From the ease of installation to the usage process, put yourself in the role of a user to experience the intelligent lock. Evaluate whether the lock offers ease of installation and what type of installation instruction manual is required. Also, assess the clarity and usefulness of the provided user manual or documentation.

Test whether the smart lock is user-friendly. This includes evaluating if the unlocking process is simple and easy, if the handle rotation force is appropriate, and the intuitiveness of the user interface used for setting up and managing the lock, among other factors.

D. Durability Testing

To ensure the product’s reliability and stability, relevant smart door lock standards have established requirements for robustness and durability. Specifically, durability requirements are specified in these standards. For example, fingerprint anti-theft locks require continuous charging for seven days, with a minimum of 30 open-close cycles per day, while still functioning properly without any malfunctions.

Simulate environmental adaptability to ensure product stability in various usage environments. The general technical conditions for lock security specify that smart locks should operate normally within a temperature range of -25 degrees Celsius to +55 degrees Celsius.

Compatibility testing should include the following aspects:

  1. Compatibility with different door types and sizes, as well as compatibility with common door configurations.
  2. Evaluation of the integration of the door locks with other security systems, such as doorbell cameras, alarm systems, and home automation hubs.
  3. Verification of integration with smart home compatibility, such as Amazon Alexa, Google Assistant, or Apple HomeKit.

By conducting rigorous compatibility testing, it can be determined whether the smart lock seamlessly integrates with various door types, security systems, mobile applications, voice assistants, and other smart home devices. This assessment helps identify any limitations or challenges in terms of compatibility, allowing users to make informed decisions when choosing a smart lock that best suits their specific needs and existing setup.

Common Questions about Smart Locks

5.1 Can I install a smart door lock by myself?

Of course. You can choose to install an intelligent lock by yourself if you are familiar with it. But please note that smart door locks are different from other products, and their installation is very important. While you can temporarily stop using other products if there are installation issues, it’s not the case with door locks.

As the saying goes, a lock is three parts usage and seven parts installation. The correct installation of a smart lock directly affects its security performance and future user experience. To reduce the probability of problems, we still recommend that you choose a professional smart lock installer to install it. Generally, they are more familiar with the installation process, so the probability of encountering issues is relatively low. 

Currently, the door lock installation personnel can be roughly divided into the following three types:

Brand Staff

Brand staff are undoubtedly the most familiar with their own products since they install them every day. Practice makes perfect, so the chances of installation issues are very low. And they also provide guarantees in terms of service, making it more worry-free. However, not all brands have their own installation teams.

Outsourced personnel

Outsourced personnel deal with various brands, so their familiarity will inevitably be less than that of brand staff. However, compared to self-installation, the installation by outsourced personnel is more reliable. Most brands arrange outsourced personnel to complete the installation of smart door locks.

Independent locksmiths

Small brands usually hire independent locksmiths to install their products. These individuals mostly deal with traditional door locks in their daily work, and their familiarity and installation skills for smart door locks vary.

5.2 How are smart door locks powered?

smart lock test 15

When purchasing a smart lock, most people consider the battery life. Currently, the power supply methods for most smart locks mainly consist of two battery types: 4 AA batteries and lithium batteries.

When making a purchase, try to choose a higher-capacity battery with longer battery life to avoid frequent replacement or charging, which can be quite bothersome.

Additionally, to cope with scenarios where the batteries are depleted, it’s best to choose a smart lock that has an emergency power supply interface. This allows the smart lock to be temporarily charged, making it more convenient to use. Currently, emergency power supply interfaces are generally Micro-USB or Type-C.

5.3 Can you provide some maintenance tips for smart locks?

smart lock test 16

Certainly! Here are some maintenance methods for your reference:

  • Avoid non-professional disassembly

The internal structure of a smart lock is often much more complex than traditional standard locks. It contains various high-tech electronic components. If you are not familiar with it, it is best not to disassemble it casually.

This is not only because its hardware design is different from traditional locks, but also because smart locks have built-in smart chips. The chip determines the security level and operation methods of the lock. Therefore, non-professionals should not attempt to install or disassemble it on their own.

  • Lock cylinder maintenance method

When the key insertion and removal become difficult during use, you can apply a small amount of graphite powder or pencil lead to the lock cylinder slot to ensure smooth key insertion and removal.

However, avoid using any other oils for lubrication to prevent grease from sticking to the pins and springs, which can hinder the rotation of the lock cylinder and prevent it from opening.

  • Avoid applying pressure to the smart lock

The lock handle is a crucial part for opening and closing the door. Its flexibility directly affects the use of the smart lock. Do not hang objects on the handle, as this seemingly convenient action can actually cause significant damage to the lock.

  • Regularly check the batteries

Regularly check the batteries, especially in areas with higher temperatures. Poor-quality batteries are prone to leakage and corrosion. If you find low battery levels or signs of leakage, immediately replace them with new batteries. Also, do not mix old and new batteries. It is recommended to use specialized batteries for smart locks.

  • Regularly wipe the fingerprint collection surface

After prolonged use, the biometric fingerprint scanner surface of a fingerprint lock may become damp or dirty. Use a dry, soft cloth to gently wipe it clean. While the security of the lock is the top priority, aesthetics are also important because it is the front entrance of your home.


5.4 Smart Locks vs Traditional Locks, which one is better?

smart lock test 17

Currently, smart locks have integrated door locks, peepholes, and doorbells, offering comprehensive functionality. However, most people’s understanding of smart locks is based on knowledge from seven or eight years ago, thinking that smart locks only have a few additional unlocking methods compared to traditional locks.

In reality, the development of smart locks has not only diversified the unlocking methods but also focused on enhancing security. Let’s compare the differences between smart locks and traditional locks.

  • Appearance: In terms of appearance, smart locks outshine traditional locks. The technological and luxurious feel of smart locks cannot be compared to traditional locks, which is quite evident.

  • Unlocking Methods: Traditional locks can only be opened using mechanical keys, while smart locks offer a variety of unlocking methods. You can always find a method that suits your preferences for unlocking. Therefore, in terms of unlocking methods, smart locks are more convenient than traditional locks.

  • Lock Cylinder: Regarding the lock cylinder, in terms of security performance, C-grade > B-grade > A-grade. Whether you purchase a traditional lock or a smart lock, choosing a C-grade lock offers the highest security. Most current locks use C-grade lock cylinders. So in terms of lock cylinders, smart locks are superior to traditional locks.

  • Lock Body: The lock body is one of the components of an entire lock. Traditional locks use mechanical lock bodies, while some smart locks use electronic lock bodies. The advantage of electronic lock bodies lies in their ability to achieve auto lock and unlock and other functions, making them more advanced, secure, and convenient.

  • Security: Smart locks have advanced features such as abnormal alert notifications and unlocking records, which traditional locks lack. These smart features allow you to monitor any abnormal situations at your door at any time, enabling preventive measures. Therefore, the security level of smart locks far exceeds that of traditional locks.

Based on the above comparisons, smart locks are more convenient and secure than traditional locks.
