China’s smart-door-lock market sold 18.01 million sets in 2023, according to an estimate from market-research firm Runto Technology reported by Sina Finance. Sales increased 2.4% from 2022. Xiaomi led online sales volume, but that does not establish Xiaomi as the leader across every channel or by total revenue.
The distinction matters for manufacturers, developers, contractors and investors: the figure covers a broad omnichannel market, while a separate estimate put household smart-lock retail at 18.7 million sets. These numbers use different market definitions and should not be treated as interchangeable.

What the 18.01 million figure measures
Runto’s estimate describes China’s full-channel, or omnichannel, smart-door-lock market. “Sets” and “units” are used interchangeably in English coverage, although the source terminology refers to installed lock products or packages rather than necessarily individual components.

It includes household demand as well as commercial, institutional and project-related purchases, such as property-development, hotel, office and other business-to-business installations. Industry coverage citing Runto said business demand represented roughly half of the sector in 2023, while consumer demand accounted for approximately 42.5%.
#1 Best Overall
- Installation is a little DIFFICULT！！！The mortise is not suitable for standard doors, some screws involve cutting, please watch the installation video carefully, the product come with an English manual, if you encounter any problems in use, please leave us a message, we will provide solutions for you! Important Notice: This product is not waterproof and should not be installed outdoors
- 4-In-1 Smart Device Integrated Security System: the security system includes a biometric fingerprint door lock, HD camera with infrared night market function, smart cat-eye, and a smart doorbell with adjustable volume level. This eliminates the need for multiple devices and provides 24/7 monitoring and real-time alerts with just one smart door lock with camera
- Fingerprint Door Lock with Camera: Using FPC Semiconductor's Live Fingerprint Capture Unit, the accuracy of fingerprint recognition can be continuously improved, thus speeding up the verification process. Indoor 1080P high-resolution color screen is especially suitable for the elderly and children at home, you can view the dynamics outside the door in real time
- Multiple Unlocking Methods: Smart door locks support face unlocking, fingerprint unlocking, card unlocking, password unlocking, temporary password unlocking, APP remote unlocking, WeChat applet, physical key unlocking and other unlocking methods. Provide more convenient unlocking methods for the elderly and children, friends and relatives visiting, and say goodbye to the trouble of being locked out of the door
- No Need to Worry About The Smart Lock Running Out of Power: Smart door lock built-in 4200mAh rechargeable lithium battery with outdoor charging port. When the lock sends out a low battery alarm, it can still open the door about 100 times, and the mechanical key can open the door at any time
That scope helps explain why the headline should not be read as “18.01 million Chinese households bought a smart lock.” Property-development demand weakened considerably, and the market also experienced pressure in traditional offline retail.
Why another estimate says 18.7 million
An AVC-based industry report estimated 18.7 million household smart locks were sold through omnichannel retail in 2023, up 3.6%. The figure comes from a different research framework and appears to focus on household retail rather than Runto’s broader market definition. It may also use different panels, channel classifications or sampling methods.
The two estimates are therefore not necessarily contradictory. Neither should be presented as an official government statistic. They are commercial market-research estimates measuring related but potentially different universes.
For readers comparing market reports, the essential checks are:
- Does the figure cover households only, or also commercial and property projects?
- Does “omnichannel” include offline retail, e-commerce and contractor-led installations?
- Is the metric unit volume, retail volume or sales revenue?
- Does “smart lock” include all biometric and connected models, or only a defined product panel?
Growth was positive, but not a boom
Under Runto’s methodology, the market reached 18.01 million sets and grew 2.4% year over year. Industry coverage citing Runto also put the market’s approximate five-year compound annual growth rate since 2019 at 6.5%.
That indicates a large and expanding category, but 2023 itself was a low-single-digit-growth year. Weak real-estate development activity affected project demand, while offline retail reportedly declined by nearly 30%. The overall market remained positive because online channels and selected higher-value products offset some of that weakness.
Online, offline and project channels moved in different directions
Runto-reported channel figures cited in industry coverage show a fragmented market:

| Channel | Reported 2023 result | Interpretation |
|---|---|---|
| Traditional online e-commerce | 4.31 million sets, up approximately 4.5% | A major consumer channel, but only one component of the total market. |
| Emerging online platforms | Approximately 1.5 million sets, up about 70% | Platforms such as Douyin and Pinduoduo gained importance. |
| Offline retail | Down nearly 30% | Showrooms and conventional retail faced significant pressure. |
| Property-development demand | Down more than 10% | New-build and fine-decoration projects weakened. |
These categories should not be added together casually. The published figures are components of a broader research model, and the available reporting does not provide enough methodological detail to confirm that every category is mutually exclusive.
For construction companies and developers, the channel split is commercially important. A project specification may be won through a property developer, architect, security integrator or contractor rather than through a consumer marketplace. Conversely, online brands can build demand among homeowners who later need installation, replacement or compatibility support.
Xiaomi led online volume—not every measure of the market
The strongest version of Xiaomi’s leadership claim is specific: Xiaomi led online sales volume. Available reporting does not prove that it sold the most units across China’s entire omnichannel market, nor that it led by revenue.
| Measure | Reported leader or result |
|---|---|
| Online sales volume | Xiaomi |
| Online sales revenue | Deschmann |
| Offline and fine-decoration channels | Kaadas |
| Leading brand group | Xiaomi, Deschmann and Kaadas were consistently among the leading brands. |
“Sales” can mean several different things:
- Sales volume: the number of locks or sets sold.
- Sales revenue: the monetary value of those sales.
- Market share: a brand’s portion of a specified market and channel.
- Retail volume: household consumer purchases, usually excluding some project demand.
- Omnichannel volume: a broader measure that may include online, offline, commercial and project sales.
A separate AVC-related report said Xiaomi held an 18% share of traditional online retail volume for household smart locks. That is a channel-specific figure, not an 18% share of China’s entire smart-lock market. The available sources also do not provide a verified Xiaomi unit total for all channels.

Industry coverage attributed Xiaomi’s online position to a combination of price competitiveness, smart-home integration, broad product coverage and an established internet-user base. Xiaomi and Mijia products can appeal to customers already using the company’s connected-home ecosystem, while online distribution makes comparison and price-led purchasing easier.
Those advantages explain distribution and adoption, not necessarily superior security, durability or reliability. Market share alone cannot establish that Xiaomi locks are safer or better supported than competing products.
For construction and housing businesses, the ecosystem question is increasingly relevant. A lock can be evaluated not only as a door fitting but also as part of access control, resident services, video intercom, remote monitoring and a wider building-management strategy.

- Secure smart lock for your front door; replaces the deadbolt lock you already have
- Keyless entry on the LED keypad so you can lock and unlock your front door without a key; keypad chimes play sounds to confirm responses, such as locking, unlocking, or turning Privacy Mode on or off
- Let someone in from anywhere; unlock the door with your phone for easy guest access
- Give unique passcode to family and guests and set a schedule to control when they work; when you don’t want to be disturbed, Privacy Mode disables the keypad so it can’t be unlocked with a passcode
- Get alerts when someone locks or unlocks the door or tries to tamper with your smart door lock
Feature development is pushing the market upward
The product category is moving beyond basic fingerprint, password and card unlocking. Reported growth areas include:
- Facial-recognition access;
- Palm-vein identification;
- Large-screen smart peepholes;
- Remote monitoring and video calling;
- Mobile-app and ecosystem integration;
- Higher-end biometric and security functions.
Runto-reported online estimates cited by Sina Finance indicated that facial-recognition locks grew 90.9% year over year. Their online share rose from 2.6% in January 2021 to 25.3% in December 2023. Large-screen peephole locks grew 64.5% year over year and reached a 38.2% share in December 2023.
These are market-monitoring estimates, not government statistics, and the shares apply to the relevant online product categories rather than necessarily to every smart lock sold in China.

Secondary coverage citing Runto estimated the average online price in 2023 at approximately RMB 1,147, down RMB 138 from the previous year. The average monthly price reportedly fell below RMB 1,000 in August, reaching about RMB 981—the first time in three years that it had crossed that threshold.
At the same time, premium segments expanded. Products priced between RMB 2,500 and RMB 2,999 reportedly grew by about 10%, while products above RMB 3,500 grew by approximately 73.9%.
This suggests a two-track market rather than a simple race to the bottom:
- Affordable and mid-priced locks expanded access and drove unit volume.
- Premium products attracted buyers with stronger biometrics, cameras, displays, monitoring and connected-home features.
The reported prices describe China’s online market in 2023. They are not current global prices and should not be used as a quotation for a construction project without checking the exact model, specification, installation requirements and local supply chain.

What the result means for construction and housing
Smart locks are becoming a more visible component of residential and building technology specifications, but the market data does not mean every project should select the highest-feature product. Contractors and developers should match the lock to the building’s operating model.
For new-build or large property projects, important questions include:

For retrofit work, physical compatibility may matter more than ecosystem features. Door thickness, lock-body dimensions, mortise type, swing direction and existing deadbolt configuration can determine whether a product can be installed without costly modification.
Methodology caveats
Source: The 18.01 million-set estimate is attributed to Runto Technology through industry reporting, primarily Sina Finance and a summary from Gizmochina.
Comparison: AVC-related coverage reported 18.7 million household smart-lock retail sets; see IPS and AVC’s research pages.
Metric: Xiaomi’s reported leadership concerns online unit volume. Deschmann led online revenue, while Kaadas led offline and fine-decoration channels.
Date: All figures describe 2023 activity. The reported RMB prices are historical estimates, not current 2026 pricing.
Bottom line
China’s 2023 smart-door-lock market was substantial, but the headline needs precision. Runto estimated 18.01 million omnichannel sets, with growth of 2.4%. Xiaomi led online unit sales, while Deschmann led online revenue and Kaadas was stronger in offline and fine-decoration channels. The competitive picture is therefore one of ecosystem and online scale for Xiaomi, premium-value strength for rivals, and continuing opportunity in construction, property and commercial installations.
