Founded in 2003, Yue-fong Mai’s has evolved from a traditional lock workshop into a global biometric tech leader. Operating within our signature 70,000㎡ “Garden Factory,” we combine three decades of craftsmanship with a 10-million unit annual capacity. We don’t just manufacture locks; we engineer the future of global access control for Tier-1 brands.
From custom high-security biometrics to industrial-grade durability, we provide rapid 3-5 day prototyping and scalable manufacturing solutions tailored to global brands, security integrators, and niche market leaders.
Finding a manufacturing partner with the capacity and compliance for our global launch was our biggest challenge. Yue-fong Mai's Garden Factory didn't just meet our volume requirements of 50k units/month; they exceeded our quality expectations with ANSI-level hardware. Their team made the Tuya ecosystem integration seamless for our product line.
For our remote asset monitoring project, we needed padlocks that could survive brutal coastal conditions. Yue-fong's smart padlocks passed the 120h+ salt spray test with zero issues. The IP67 rating is genuine—our clients are extremely satisfied with the biometric reliability in heavy rain and humidity.
As an Airbnb solution provider, our hardware needs are unique. Yue-fong Mai's 'Specialty Locks' team provided us with a technical drawing and prototype for a customized key box in just 4 days. The scalability from prototype to mass production was flawless, significantly accelerating our time-to-market.
With 30 years of secure manufacturing, we are the invisible powerhouse behind global security brands, Airbnb integrators, and industrial site operators. Our commitment to ‘Zero-Defect’ quality is validated by partners in over 100 markets.
We don’t just supply locks; we solve access challenges. From high-traffic commercial hubs to extreme outdoor industrial sites, our tailored biometric solutions ensure uncompromising safety and operational efficiency for global partners.
