Ever unboxed a sleek smart lock from abroad and wondered if it really keeps your home secure? Um, the smooth metal faceplate and soft LED glow look impressive, but could your lock be less safe than you think? Let’s find out.
In China, door lock OEM factories feel like mini security cities. They bring engineers, quality labs, and automated lines under one roof. Every circuit and component goes through design, molding, and stress tests. No corners cut.
You’ll find fingerprint readers (a reader that checks your unique fingertip pattern) sitting next to RFID deadbolts (locks that open with radio signals). These parts power more than half of the global smart-lock market. At that scale, safety can’t be an afterthought.
So what keeps your lock from failing when it matters? Here are five factory checkpoints to give you real peace of mind.
5 China door lock OEM factory Guarantees Safety
At their heart, China door lock OEM factories (original equipment manufacturer) bring engineers, automated lines, and quality control labs together under one roof. They design the molds, assemble parts, and test each lock to meet exact specs.
From biometric fingerprint modules (reader that checks your unique fingertip pattern) to RFID deadbolts (locks that open with radio signals), these factories power the global smart-lock market. Hmm, Shenzhen’s supplier network delivers circuit boards and sensors just in time.
Buyers often scout new designs at the Canton Fair in Guangzhou. It’s like a big showcase for lock tech and door hardware.
Most factories hold ISO 9001, CE, FCC, RoHS, China PSB (Product Safety Bureau), UL/ETL, and TÜV certificates. Those badges back their safety claims.
Smaller shops crank out about 30,000 lock sets a year. Large industrial campuses can hit over 500,000.
Be-Tech in Foshan covers 35,000 square meters with five R&D lines. They roll out 300,000 sets annually.
KEYU Intelligence’s Jiangmen facility spans 36,000 square meters and pushes out 500,000 units each year. Impressive.
Zhongshan Yangge’s six-line plant covers 40,000 square meters and pumps out 50,000 locks a month.
This cluster helps make Guangdong an electronics hub. Meanwhile, sites in Zhejiang focus on premium mortise and lever handles.
These factories offer end-to-end OEM/ODM (original design manufacturer) services. Think prototype tooling in seven days, injection molding, electronic firmware, mobile-app integration, and cloud-based management.
Sample requests ship in 7–15 days, and most buyers start with 100–500 sets.
Bulk runs wrap up in 30–60 days, and volume pricing tiers unlock deeper discounts.
Many factories even handle global dropshipping for smaller brands.
As a B2B brand, you’ll find a smart lock supplier with stable quality here. And you can learn more about our global reach on the home door lock factory China page.
Manufacturing Capabilities at China Door Lock OEM Factory
China’s door lock OEM factories run like mini cities full of humming machines and precise tools. You’ve got big automated lines from KEYU and Be-Tech, plus specialist spots like iLockey, Sinovo and YonAnn. Together they pump out 200,000 to 600,000 locks every month. Impressive.
We handle die-casting (shaping molten metal), CNC machining (computer-controlled cutting machines) and injection molding (forming plastic parts) all on site. There’s even a prototype lab and tooling dev team turning ideas into real locks in no time. No outsourcing delays. Solid.
Every assembly line has twelve QC checkpoints (quality control spots) to catch issues early. Surface treatments – powder coating, plating, polishing – give you that smooth metal faceplate you can feel. And you get a reassuring click with every turn. Exactly what you want in a lock.
We keep tooling and mold making in house to skip those back-and-forth handoffs. That means tighter timelines and builds you can trust. Peace of mind. Um, we take quality seriously.
| Workshop | Function |
|---|---|
| Die-casting | Zinc-alloy lock bodies |
| CNC Machining | Precision cylinders and housing parts |
| Injection Molding | Plastic components and keypads |
| Assembly Lines | Automated with 12 QC stations |
| Surface Finishing | Powder coating, plating, polishing |
| Prototype & Tooling | Sampling and development |
Product Range and Feature Integration in China Door Lock OEM Factory
Here in our factory we crank out every type of door lock you can imagine. We make fingerprint cylinders (locks with fingertip readers) for quick and secure access. Next up are biometric motor-control boards (tiny brains that move the bolt), RFID deadbolts (locks opened by radio tags), and keypad locks with anti-peep layouts (to keep your PIN undercover).
We even offer video-intercom mortise locks (locks with a camera and speaker). Let me rephrase, they’re like a mini front desk built right into your door. There are also multi-point hook systems for sliding doors and automatic mortise mechanisms that retract the bolt with a soft LED glow when you swipe.
Smart features? You bet. Many models include Bluetooth modules so you tap your phone like a transit card. You can also choose Zigbee and Z-Wave variants that plug into home hubs. Or pick a Wi-Fi latch for remote unlocks over the cloud.
On the mechanical side, our locks can have bump-resistant cores (to resist forced twists), drill-proof housings, and emergency USB-power interfaces tucked under a neat cover. Property managers love our master-key setups – they let you manage dozens of units without chaos.
Customization is a breeze with our modular design. Swap in a Bluetooth board or a Wi-Fi latch with plug-and-play connectors. Firmware comes preloaded or you can fine-tune it to match your mobile app. That way, your locks align with your brand’s look and feel, even down to custom dashboard icons.
Smooth integration. Zero headaches. We’ve got CE certification and two decades of testing in dusty, rainy, and hot conditions – so you can trust your locks every day.
Quality Assurance and Certifications for China Door Lock OEM Factory
At our China door lock OEM factory, every lock starts with an ISO9001 audit (a factory quality system review). We earn CE marks (European safety approval) and UL certification (US safety check) to prove our locks meet top safety rules. And we run RoHS tests (making sure no harmful substances get into our metal). Then each lock body faces a salt spray test (up to 96 hours) to see how it stands up to rust. We also put them through a durability cycle test of 200,000 to 250,000 pulls and pushes. Solid proof they last.
We don’t stop there. Our fail-safe checks include temperature and humidity cycling, vibration testing, mechanical fatigue tests (to catch weak spots), 48-hour aging, and stress screening in harsh conditions. For every batch, our team follows a six-step QC workflow. And yes, we record each sample test on video. That thorough routine means defect rates stay under 0.15% and delivers CE/FCC certified smart locks that you can trust.
| Test Type | Standard | Duration/Cycles |
|---|---|---|
| Salt Spray | ISO 9227 | 96 hours |
| Durability Cycle | EN 14846 | 200,000–250,000 cycles |
| Vibration | IEC 60068-2-6 | 5 g, 10–500 Hz |
| IP Rating | IP54/IP66 | Checked per batch |
This strict routine makes sure each lock meets global safety and reliability standards. You get worry-free performance and real peace of mind for any project.

We stock spare parts (replacement modules, cylinders, and bolt sets) for at least two years after production. When something wears out, there’s no panic. Just log into our portal, place your order, and we ship replacements fast. That way your team never misses the reassuring click of a smooth metal faceplate. Solid.
Every lock ships with a technical data sheet (a document showing specs, wiring diagrams, and performance charts). You also get a user guide and custom-branded instruction manual (hardcopy booklet). All docs come in PDF and hardcopy so installers and end users feel confident. Hmm, that makes setup a breeze.
We set up NDA (nondisclosure agreement) and IP protection (intellectual property protection) before any design leaves our campus. Need help? We jump on a video call for live troubleshooting. Then we push firmware OTA (over-the-air updates) to tweak features or patch security. You’re never in the dark.
