Kaadas (凯迪仕 / Shenzhen Kaadas Intelligent Technology Co., Ltd.)

Company Overview

Kaadas (凯迪仕) is a Shenzhen-headquartered smart lock business that has grown from a consumer brand into a fully integrated manufacturer with its own OEM/ODM programme. Its head office is in Xili, Nanshan District, Shenzhen, and the group runs factories in Zhuhai (Doumen District) and Wenzhou (Ouhai District). Company communications around the 2024 opening of a very large Wenzhou plant also reference a third manufacturing base in Zhongshan.

For a foreign buyer the relevant fact is that Kaadas operates on two tracks: its own brand for domestic and export markets, and an OEM/ODM track that supplies lock brands and security-integrator customers. That is a rarer combination than it sounds — many Chinese consumers-facing brands do not have a real ODM programme, and many ODM houses have no brand-quality engineering process.

Manufacturing and Capability

Kaadas states that it owns the full in-house supply chain: industrial design, structural and hardware engineering, firmware, app and cloud development, and the physical manufacturing steps of die casting, CNC machining, plating and automatic assembly. The company quotes three manufacturing bases covering about 287,000 square metres and annual capacity above 5 million lock sets. Those figures come from the group's own ODM pages and should be treated as company claims; verify capacity and current loading with a factory visit.

The engineering scope matters more than the headline capacity. Smart locks fail on the integration points: latch throw, motor and clutch durability, fingerprint module performance in cold weather, and what happens to the lock when the phone is offline. A manufacturer that writes its own firmware and app is more likely to be able to fix these. It is also more likely to have a cloud dependency you should interrogate, as a manufacturer that outsources software would.

Main Products

  • Standalone smart locks — keypad, fingerprint and card access without app dependency.
  • Bluetooth locks with app-based management for short-range control.
  • Wi-Fi locks with voice assistant and smart-home integration (Alexa, Airbnb, Apple HomeKit per the company's ODM listing).
  • Wi-Fi bridge modules to avoid a separate hub.
  • Complementary hardware: mortise latches, cylinders, handles and levers.
  • Dealer and ODM ranges, including customised lock bodies and branding for lock companies and integrators.

Certifications and Testing

Kaadas references iF and Red Dot design awards for several products, and states that its locks meet industry standards and pass strength, environmental and reliability testing, but the group site does not publish a certificate list. That is normal for this category, and it means you must specify certificates by model and market:

  • North America: ANSI/BHMA A156.25 or A156.36 where relevant, UL 1568 or the appropriate electrical standard, FCC Part 15 for the radio, and California Prop 65 for materials if selling in the US.
  • Europe: CE with RED (2014/53/EU) for radio, EN 1906 for lever handle hardware, EN 179/1125 if the lock is on an emergency escape route, and EN 1634 for fire door use if applicable.
  • Elsewhere: GB 21556 is the Chinese national lock standard; it is a useful manufacturing benchmark but not a substitute for the destination-market certificate.

Ask specifically which certificate body and which model. The most common failure in this category is a supplier sending a CE declaration for the base model while shipping a variant with a different radio module.

Key Facts

  • Headquarters: 11F-14F, Building B2, Phase 2, Creative City, Chuangke Road, Xili Street, Nanshan District, Shenzhen, Guangdong 518055, China (company ODM pages).
  • Factories: Zhuhai, Guangdong (Zhugang Road, Fushan Industry Area, Qianwu Town, Doumen District); Wenzhou, Zhejiang (No. 599 Sanxi Road, Guoxi Street, Ouhai District).
  • Production bases: three, about 287,000 sq m (company claim).
  • Capacity: over 5 million lock sets per year (company claim).
  • Ownership: private, unlisted.
  • Track record: company sources describe the brand as being founded in 2009 by Su Zhiyong; public listing outside China is not available, so ownership and financials are not independently verifiable.

Contact and Website

The trade-facing ODM information is at kaadasgroup.com, including an ODM/OEM section with a contact form. The consumer and domestic brand site is www.kaadas.com. Treat the details published on those official sites as authoritative; do not use contact details from trading platforms or scraped directories.

Sourcing Notes

If you are considering Kaadas for an own-brand lock, the ODM page is a reasonable starting point because the group already sells to lock brands and integrators. Expect to bring your own market certificates and your own app decision — an own-brand lock that depends on the factory's cloud is a long-term obligation, not a purchase. Also verify the fingerprint module supplier and the motor/clutch life data with test records, and ask for a sample with the exact firmware build you will receive in production. Locks are one of the few categories where a firmware change between sample and production can invalidate a test report.
