10 Smart Lock Manufacturers in China (2026)

Search “smart lock manufacturers in china” and the results split into two worlds: Wenzhou-area factories that grew out of mechanical lock hardware, and Shenzhen-area factories that added fingerprint readers, cameras, and Tuya Wi-Fi modules to electronic deadbolts. Both clusters can build a good lock; they fail in different ways.

For buyers, the real divide is not geography — it is whether the supplier understands the certification stack your market demands. A fingerprint lock that ships fine on Tuya/TTLock may still fail ANSI/BHMA Grade 2 cycle testing, or carry an FCC report for a different SKU. The factory-floor capability in China is there; the gap is usually in documentation, platform choice, and outdoor durability. The typical OEM price band for a fingerprint smart lock sits between $15 and $60 at factory-exit, which tells you the category is competitive and that small spec differences decide whether a unit is entry-level or premium.

This list covers ten manufacturers we have either visited or screened for US and EU smart home brands. I have grouped them by cluster and platform, with honest filters on where each is — and is not — the right fit. For the broader sourcing workflow, our smart home device sourcing guide covers verification and BOM checks.

Quick comparison

“MOQ hint” reflects typical white-label OEM minimums for this category; confirm the exact figure before sampling because custom enclosures, private-label packaging, and certification work all move the number.

How we evaluate

We score smart lock factories on six points:

1. Certification scope. The FCC ID or CE Declaration must match the exact SKU, not a sibling model. For the US, a Wi-Fi or Bluetooth lock is a certified radio device and needs an FCC ID you can verify in the FCC Equipment Authorization database. For the EU, read the CE Declaration against the CE marking framework to confirm RED and RoHS coverage — for a radio-equipped lock, RED’s essential requirements absorb the LVD and EMC objectives, so those directives do not apply separately.
2. Mechanical durability. ANSI/BHMA Grade 1, 2, or 3 cycle testing decides whether a lock survives commercial traffic. Residential projects often accept Grade 2; high-traffic commercial entrances need Grade 1.
3. Platform ecosystem. Tuya/TTLock dominates Chinese OEM smart locks because it offers a ready app and cloud. Matter support is still a tech watershed — most factories list it only as a custom or roadmap option, not the default.
4. Outdoor rating. IP54 is the practical minimum for exterior installation; anything below that belongs indoors. Salt-spray testing matters for coastal or humid markets.
5. Production scale and export experience. A factory with regular US/EU shipments understands labeling, documentation, and recall-readiness better than one that sells only domestically.
6. Sample-to-production consistency. Fingerprint modules, face-recognition sensors, and Wi-Fi chipsets are swapped frequently. A good factory locks the approved BOM before mass production.

Hold every entry below against these six.

The top 10 manufacturers

1. Wenzhou Akada Foreign Trade Co., Ltd. / Akada Smart

Akada Smart operates out of Wenzhou, the lock-hardware cluster in Zhejiang, and builds fingerprint, password, card, and app-enabled smart locks. Its catalog centers on hotel and residential smart locks, and the company states that it tests to ANSI/BHMA standards — relevant for US residential and commercial door hardware channels, though you should ask for the actual test report on the specific SKU rather than relying on the claim.

The trade-off is that Wenzhou factories are not always as close to the fastest firmware iteration as Shenzhen peers. If you need deep app customization or rapid Tuya module swaps, confirm their software team size up front and lock the firmware version in writing.

Key details:

• Base: Wenzhou, Zhejiang
• Main products: Fingerprint / password / card / app smart locks
• Cert focus: tests to ANSI/BHMA (per company materials), CE/FCC
• Strength: hotel and residential lock catalog with mechanical-lock heritage
• MOQ hint: 300–500 units

Best for: brands that want a Wenzhou hardware-heritage factory for hotel or residential locks, with ANSI/BHMA test reports requested per SKU.

Not ideal for: buyers who want fast firmware iteration or a proprietary app built from scratch.

2. Zhongshan KESAF Hardware Technology Co., Ltd.

KESAF is a Zhongshan-based factory that blends mechanical lock heritage with electronic code access. Its products include outdoor-rated electronic code locks and mortise locks — a fit for gates, garden doors, and commercial entrances exposed to weather.

Because the company straddles mechanical and electronic lines, ask specifically about IP rating and salt-spray testing if you are buying for outdoor use; not every SKU carries the same environmental seal.

Key details:

• Base: Zhongshan, Guangdong
• Main products: Mechanical + electronic code locks, mortise locks
• Cert focus: IP54+, CE
• Strength: Outdoor-rated hardware
• MOQ hint: 200–500 units

Best for: outdoor or semi-outdoor installations that need electronic code access.

Not ideal for: buyers who need biometric or camera features as the default SKU.

3. LaDing Technology / Kaisstar

Kaisstar, under LaDing Technology, runs a 12,000 m² factory in Zhongshan with a stated capacity of 1.2 million locks per year, focused on fingerprint smart locks and hotel locks built around Tuya and TTLock platforms. That footprint makes it one of the more sizeable hardware-electronics hybrids on this list.

The Tuya/TTLock focus means faster time-to-app for brands that do not want to build their own cloud. If you need a proprietary app or Matter support, treat it as a custom project with longer lead time.

Key details:

• Base: Zhongshan, Guangdong
• Factory: 12,000 m², ~1.2M locks/year stated capacity (company figures)
• Main products: Fingerprint smart locks, hotel locks
• Platforms: Tuya, TTLock
• MOQ hint: 200–500 units

Best for: residential and hospitality brands that want Tuya/TTLock out of the box.

Not ideal for: buyers who need Matter compatibility or a fully white-label app ecosystem.

4. Shenzhen Jcsmarts Electronic Co., Limited

Jcsmarts is a Shenzhen factory building digital, fingerprint, hotel, and Tuya locks, with ISO 9001 as its stated quality backbone. The product range is broad enough to cover residential, hospitality, and light commercial use cases.

Like many Shenzhen electronics-led lock factories, Jcsmarts moves quickly on new modules. Verify that the SKU you sample matches the certification files you are shown, because module swaps between samples and production are common.

Key details:

• Base: Shenzhen, Guangdong
• Main products: Digital, fingerprint, hotel, Tuya locks
• Cert focus: ISO 9001, CE/FCC
• Strength: Broad SKU range, fast iteration
• MOQ hint: 300–500 units

Best for: buyers who want a wide catalog under one supplier and fast sample turnaround.

Not ideal for: buyers who need one deep specialty — ANSI-grade mortise hardware, camera locks, or Matter firmware — rather than a broad generalist catalog.

5. Shenzhen Everlead Electronics Co., Ltd.

Everlead specializes in higher-feature smart locks, including units with cameras and 3D face recognition, running on Tuya/TTLock. These are the SKUs that compete with premium residential and small-commercial access-control setups, including projects that combine door locks with access control panels.

Camera locks bring extra compliance layers: privacy regulations, cloud storage terms, and RF emissions from both the lock radio and the video stream. Make sure your certification scope covers the full camera-plus-lock assembly, not just the door-lock portion.

Key details:

• Base: Shenzhen, Guangdong
• Main products: Smart locks with camera, 3D face recognition
• Platforms: Tuya, TTLock
• Strength: Premium feature sets
• MOQ hint: 300–500 units

Best for: premium residential or small-commercial brands adding camera or face recognition.

Not ideal for: budget-first projects that do not need camera or 3D face features.

6. Shenzhen Coolseer Technology Co., Ltd.

Coolseer is a Shenzhen manufacturer covering the full smart-home range — switches, lighting, sensors, gateways, and smart locks — with a catalog of 500+ SKUs and platform support spanning WiFi, Zigbee, Bluetooth, Matter, and HomeKit. Smart locks are one product line within that range, not the company’s sole focus.

That breadth is the reason to shortlist it. A brand building a multi-product smart home line can source locks, switches, and sensors from one factory and keep app behavior and ecosystem certification consistent across SKUs. The trade-off is depth: a full-range generalist will not match a lock-only specialist on mechanical engineering, so check bolt materials, cycle-test reports, and mortise options on the specific lock SKU before sampling.

Key details:

• Base: Shenzhen, Guangdong
• Main products: smart locks, switches, lighting, sensors, gateways (500+ SKUs)
• Platforms: WiFi, Zigbee, Bluetooth, Matter, HomeKit
• Strength: one factory for a multi-ecosystem smart home line
• MOQ hint: 200–500 units

Best for: brands that want smart locks plus other smart home SKUs from one factory, across ecosystems including Matter and HomeKit.

Not ideal for: buyers who want a lock-only specialist with deep mechanical-lock heritage.

7. Shenzhen Nordson Electronic Co., Ltd.

Nordson’s main business is access-control hardware: magnetic locks, electric bolt and strike locks, door contacts, exit buttons, and access controllers, with a selection of keypad and standalone electronic lock SKUs alongside. Its catalog sits closer to commercial door-access infrastructure than to consumer smart deadbolts.

That profile fits buyers assembling a complete door-access package — controller, reader, maglock, and a keypad lock from one supplier, on one set of paperwork. Pay attention to fail-safe versus fail-secure wiring specs and holding-force ratings on the maglock side; those numbers matter more here than app features.

Key details:

• Base: Shenzhen, Guangdong
• Main products: magnetic locks, electric bolt/strike locks, door contacts, access controllers, keypad locks
• Cert focus: CE/FCC
• Strength: access-control hardware breadth
• MOQ hint: 300–500 units

Best for: commercial access-control projects that need maglocks, controllers, and keypad locks from one supplier.

Not ideal for: residential smart deadbolt programs built around fingerprint, camera, or app features.

8. Kotonlink (Shenzhen) Technology Co., Limited

Kotonlink is a Shenzhen supplier building Tuya/TTLock smart locks with 3D face recognition. It sits in the same feature tier as Everlead but with a stronger emphasis on the Tuya/TTLock app path.

3D face recognition modules add cost and calibration complexity. Confirm that the sensor vendor and algorithm are locked for production, and that the certification report covers the face-recognition variant, not a lower-spec sibling SKU.

Key details:

• Base: Shenzhen, Guangdong
• Main products: 3D face recognition smart locks
• Platforms: Tuya, TTLock
• Strength: Face recognition at OEM scale
• MOQ hint: 200–500 units

Best for: brands that want 3D face recognition on a Tuya/TTLock app path.

Not ideal for: buyers who need the lowest unit cost and can accept fingerprint-only access.

Shenzhen Kaadas Intelligent Technology is one of the larger dedicated smart lock manufacturers in China, with over 2,000 employees, 400+ patents, and vertically integrated in-house production covering CNC machining, die-casting, injection molding, and assembly. The company expanded into North America in 2023 and actively offers dealership, OEM, and ODM partnerships.

Kaadas is strongest for buyers who need a premium residential or commercial smart lock with serious mechanical and firmware credentials. The product range covers fingerprint, face recognition, Wi-Fi, Bluetooth, and Z-Wave locks, plus smart-home gateways. The trade-off is MOQ and minimum volume: Kaadas is not a 200-unit Alibaba-style supplier.

Key details:

• Base: Shenzhen, Guangdong
• Scale: 2,000+ employees, 400+ patents
• Main products: fingerprint, face recognition, Wi-Fi, Z-Wave smart locks
• Cert focus: ANSI/BHMA, CE, FCC, RoHS

Best for: hotel and residential smart lock projects that need hardware durability and OEM flexibility.

Not ideal for: buyers who only want the fastest firmware iteration or deep app customization.

How to verify any supplier on this list

Before you pay a deposit, treat every smart lock factory the same way: check the certificate against the exact SKU, test the platform, and inspect the mechanical assembly. Start with the FCC ID or CE Declaration of Conformity. For US-bound Wi-Fi or Bluetooth locks, the FCC ID must match your exact model; for the EU, the CE Declaration must cite RED and RoHS — RED’s essential requirements cover the LVD and EMC objectives for radio-equipped locks, so those directives should not appear as separate line items.

Next, ask for the bill of materials or a photo of the PCB to confirm the fingerprint module, Wi-Fi chipset, and camera sensor match the spec sheet. Module swaps between the sample you approved and the production run are the most common source of certification drift in this category.

Finally, run a mechanical check: mortise material, bolt throw, cycle count, and IP rating if the lock will sit outdoors. If you cannot visit yourself, book a factory audit service that includes production-line photos and certificate cross-checks. The full supplier vetting procedure covers company registration, licensing, and certificate checks; for category-specific BOM and platform checks, see our guide to sourcing smart home devices.

Frequently asked questions

Where are smart lock manufacturers concentrated in China?

China’s smart lock production sits mainly in two clusters. Wenzhou, Zhejiang, is the historical hardware hub — suppliers there typically come from mechanical lock and hardware backgrounds, which shows in their ANSI/BHMA-grade deadbolts and mortise engineering. Shenzhen and the surrounding Pearl River Delta is the electronics cluster; factories there source fingerprint modules, Wi-Fi chipsets, camera modules, and Tuya/TTLock firmware locally. Zhongshan, between Shenzhen and Guangzhou, sits in the middle — several manufacturers combine hardware tooling from the region with electronics integration. For buyers, the choice matters: if your product needs heavy mechanical durability certification, Wenzhou or Zhongshan hardware-led factories are a natural fit; if you need fast firmware iteration, app integration, or camera/face-recognition features, Shenzhen is usually closer to the component source.

Do Chinese smart locks support Matter or only proprietary apps?

Most Chinese OEM smart locks today ship on the Tuya Smart Life or TTLock ecosystems, not Matter. Tuya/TTLock gives buyers a ready-made app, cloud backend, and white-label path without building firmware from scratch — that is why the majority of factories on this list list Tuya or TTLock in their spec sheets. Matter-over-Thread support is still rare at the OEM level; factories that mention Matter are usually referring to a roadmap SKU or a specific module, not the default reference design. If your brand needs Matter compatibility, plan for a separate firmware module and longer development time, and confirm the exact certification path before sampling. For most entry-to-mid-range residential locks, Tuya/TTLock remains the practical default.

What certifications does a smart lock need for the US and EU?

For the United States, a smart lock with Bluetooth or Wi-Fi needs FCC certification and an FCC ID; the grant must match the exact model you are importing. Mechanical durability is usually validated by ANSI/BHMA Grade 1, 2, or 3 testing, with Grade 1 rated for the highest cycle counts. For the EU and UK, a radio-equipped lock needs CE/UKCA marking under the Radio Equipment Directive (RED), whose essential requirements absorb the LVD and EMC objectives, plus RoHS; some markets also expect IP54 or higher for outdoor installation. The most common documentation gap we see is a test report that covers a different model number or a ‘family’ certificate that does not include your exact SKU. Always cross-check the FCC ID in the official FCC database and read the CE Declaration of Conformity against the directives that apply to your product.

What is the typical OEM price range for fingerprint smart locks?

At factory-exit level, a basic fingerprint smart lock from China typically lands between $15 and $60 per unit for OEM orders, depending on feature set, material, and volume. A simple fingerprint-only lock with a zinc-alloy body and TTLock firmware usually sits at the lower end, around $15–$30. Adding Wi-Fi, a camera, or 3D face recognition pushes the unit cost toward $40–$60 or higher. MOQs usually start around 200–500 units for white-label builds with existing shells; custom enclosures, private-label apps, or ANSI/BHMA-grade hardware can push both price and MOQ up. These figures are FOB-China estimates; final landed cost depends on certification, packaging, and freight.

Final word

Smart lock sourcing in China is not about finding the “best” factory; it is about matching the factory’s mechanical and firmware strengths to your market’s certification and platform requirements. Wenzhou and Zhongshan factories often win on hardware durability; Shenzhen factories win on electronics speed and feature integration. The biggest avoidable mistake is assuming the certification file on the sales desk covers the exact SKU you are buying — it often does not.
