With the comprehensive implementation of the new national standard GB 21556.2-2025 “Safety Technical Requirements for Locks – Part 2: Burglary-resistant Locks” and the recommended national standard GB/T 44602-2024 “Cybersecurity Technology – Technical Specifications for Smart Lock Cybersecurity,” the smart lock industry has entered its strictest safety regulatory threshold to date. The new standard mandates that smart locks must adopt a Grade C true-insert bolt structure, ensuring that the technical unlocking resistance time is no less than 15 minutes (with some high-standard products reaching 270 minutes), and that the physical locked state remains intact even if the exterior panel is damaged. In terms of biometrics, the new regulations explicitly phase out 2D facial recognition and conventional optical fingerprint sensors, mandating the use of 3D structured light/dual-infrared facial recognition with anti-spoofing capabilities and semiconductor live-fingerprint modules. Additionally, the new rules for the first time incorporate requirements such as local encrypted data storage, TLS-encrypted communication transmission, anti-“black box” strong magnetic interference protection, and national cryptographic security chips. This regulatory transformation is reshaping the technological landscape of the security hardware sector, pulling industry competition away from homogenized price wars and back to a contest of genuine technological strength. Low-end assembly plants without R&D capabilities will be rapidly weeded out, and the supply chain is accelerating its concentration toward leading manufacturers that possess both high-end mechanical precision engineering and cybersecurity development capabilities.
