Smart locks represent a key product category in the upgrading of China’s lock industry supply chain. Manufacturing hubs in Zhongshan and Shenzhen (Guangdong) and Wenzhou (Zhejiang) host complete supply chains—ranging from lock body hardware to smart electronic control systems—making China the source of the vast majority of the world’s smart locks.
For overseas B2B buyers, evaluating a manufacturer involves six core criteria: full supply chain capabilities (in-house R&D and production of lock bodies, electronic controls, and complete units); biometric solutions (fingerprint, 3D facial recognition, palm vein, or finger vein); security levels (Class C cylinders, dual-system architecture, and tamper resistance); lock body compatibility (international mortise standards such as 6085, 6068, and 5050); certifications and compliance (CE/FCC/RoHS, ANSI/BHMA, EN 12209, and Ministry of Public Security Class C); and the depth of OEM/ODM customization services alongside bulk procurement experience.
Drawing on publicly available industry data, this article outlines the market tiers of smart lock manufacturers, price ranges, and strategies for selecting the right supplier.

- Adoption of multimodal biometrics: Combinations of 3D face recognition and palm/finger vein scanning are becoming standard features on high-end flagship models;
technologies such as Swedish FPC semiconductor fingerprint sensors, under-display fingerprint sensors, and instant “wave-to-unlock” (contactless gesture) capabilities are filtering down to mid-range products. - Integration of smart peepholes and video intercoms: Features such as 2MP peephole cameras, 110-degree wide-angle views, indoor HD color screens, three-party video intercoms, voice-changing calls, and AI-based loitering detection/capture are being integrated into door locks, merging security monitoring with access control.
- Fully Automatic Lock Body & Radar Sensing: Proprietary fully automatic lock body (rapid and quiet operation); 24GHz automotive-grade radar for 24-hour detection; persistent Wi-Fi connectivity;
and integration with smart home ecosystems (Tuya, TTLock, HomeKit, Zigbee). - Rental Sector & Bulk Procurement Growth: Smart upgrades for affordable rental housing and long-term rental apartments are driving bulk procurement demand. Kaadas has won bids for major projects such as Shenzhen Talent Housing and Tencent’s “Penguin Island.”
Smart rental solutions—combining IoT hardware, business management systems, and AI—have become a key focus for partnerships with major clients (based on Kaadas’s public data). - Overseas Certification & Global Expansion: Compliance with certification standards—such as European EN 12209, US ANSI/BHMA, UL 1034, China’s Ministry of Public Security Grade C, CE, FCC, RoHS, and UKCA—serves as the threshold for cross-border market entry.
Original manufacturers holding certifications for multiple markets (e.g., Fuyu, Tenon) possess a distinct advantage in global expansion.
V. Recommendations for Overseas B2B Procurement
- Select Manufacturers Based on Positioning: For high-end brand distribution and real estate bulk procurement, choose major vertically integrated manufacturers like Kaadas or Dessmann. For high-volume OEM/ODM orders, opt for listed companies and major original manufacturers like Tenon or Fuyu. For specialized applications—such as thermal-break aluminum or specialty door types—select specialized manufacturers like Huawei Kedi.
For hotel and apartment scenarios, choose ecosystem solution providers like Locstar. - Five Key Areas for Factory Audits: End-to-end in-house capabilities (no outsourcing) for lock body hardware, PCB/SMT, and final assembly; presence of fully automated production lines, CNC machining, and industrial robots; professional testing laboratories (vibration, high/low temperature, salt spray, and cycle durability testing); ISO9001 and third-party certifications (SGS, EUROLAB, TUV); and systems for batch traceability and incoming material quality control.
- Six key areas for sample testing: fingerprint recognition speed and error rates (0.3s, FRR ≤1%, FAR ≤0.001%); 3D face/palm vein recognition rates in low-light and mask-wearing scenarios; effectiveness of Class C lock cylinders and anti-prying/anti-duress alarms; compatibility of lock bodies (e.g., 6085/6068) with target door types; app ecosystem (Tuya/TTLock/HomeKit) and remote management capabilities;
and dual-battery life plus Type-C emergency power supply. - Clarify MOQ and lead times: 1–2 units for stock items, 50–300 units for OEM/private labeling, and project-based terms for full customization; 3 days for samples, 1–2 weeks for bulk orders;
confirm lock body specifications, door thickness range (40–120mm), app white-labeling/private deployment options, and firmware upgrade services. - Verify certifications and compliance: European EN 12209/CE; US ANSI/BHMA and UL 1034; Ministry of Public Security Class C lock cylinder standards; CE/FCC/RoHS/UKCA; IP55/IP65 waterproofing;
select a factory that supports third-party factory audits, batch traceability, open SDK/API integration, and long-term firmware updates.
