SHIELD WORKS · SECURITY HARDWARE & LOCKS
OEM manufacturing for lock and security hardware brands: precision mechanisms, smart access control, and secure storage, made under black-box protocols in a fingerprint-access facility.
Shield Works manufactures locks, access control, and security hardware for Western brands from a facility built around the same principle as the products: controlled access.
Production runs under black-box protocols in fingerprint-access rooms. British owned and managed, in Zhuhai, China.
Who We Are
Security brands face a unique manufacturing problem: every drawing, tolerance, and keying chart you share is a potential vulnerability. The right partner is not just capable of precision work, it is structured so that no supplier, operator, or visitor can ever assemble the full picture.
Shield Works runs that structure as standard: appointment-only site entry, floor-based access approval, fingerprint-controlled assembly rooms, and supplier isolation, so the mechanism your customers trust is protected from the day it enters production.

Safeguarding your innovations
A lock mechanism in the wrong hands is a blueprint for defeating it. Black-box workflows keep operators on their own task, suppliers never see the complete mechanism, and IP-sensitive builds run in fingerprint-access rooms.
Multi-component precision
Cylinders, levers, springs, and machined bodies across multiple suppliers and materials, integrated in-house with cycle, force, and finish testing so the mechanism performs the same on unit one and unit fifty thousand.
Electronics integration
Keypads, biometrics, wireless modules, and battery systems assembled in a dedicated ESD-controlled room, with controlled firmware loading and credential security built into the process.
Quality proven by abuse
Cycle testing, corrosion and ingress resistance, and force testing against your specification, with dual-layer verification by an independent C2W Group engineer who reports directly to you.
British management
British owned and managed, with Western engineering oversight, binding NDAs signed before any technical discussion, and audit-ready documentation throughout.
C2W Group heritage since 2005
Backed by the C2W Group’s 20 years of China manufacturing across machined, cast, and electro-mechanical products for Western brands.
What We Build
Security products engineered for precision, durability, and confidentiality, from traditional mechanisms to connected access control.
Precision-machined lock bodies, cylinders, and shackle systems built and tested to specification.
Keypad, biometric, and app-connected locks with electronics assembled in our ESD-controlled zone.
Hinges, handles, closers, and security furniture in steel, brass, and zinc alloys with durable finishes.
Secure boxes, cabinets, and storage systems combining fabricated steel, locking mechanisms, and electronics.
Tamper-resistant enclosures and housings for security and monitoring equipment.
Keying systems, accessories, and spare-part programmes that support the product line after launch.
What we build
Representative of the categories we manufacture and assemble in Zhuhai, across machined brass and hardened steel, zinc alloy, and the electronics that turn a mechanical lock into a connected one. Every programme is built to the client's own design and keying specification.
Padlocks
Machined brass and hardened shackles, with the keyway and shackle fit checked on the line rather than sampled at the end.
Smart and biometric padlocks
Fingerprint and Bluetooth modules fitted in the ESD-controlled electronics room, then function-tested as a finished lock.
D-locks and cycle security
Hardened shackles over-moulded to protect paintwork, assembled and keyed to your own cylinder specification.
Smart deadbolts
Keypad, motor and mechanical override built as one assembly, so the lock still works when the battery does not.
Gate and outdoor locks
Stainless and marine-grade finishes for exterior use, with the latch and keep supplied as a matched set.
Cylinders and master-keyed suites
Euro-profile cylinders pinned to your keying chart, from single-keyed units to a master suite across a whole building.
Multipoint window and door mechanisms
Espagnolette strips, gearboxes and keeps built as a mechanism and cycled before packing, not assembled at the customer.
Safes and secure storage
Fabricated steel bodies with the bolt work, keypad and override lock integrated and tested as one unit.
Keys, blanks and spare parts
Cut keys, blanks and service parts kitted and held so a line can be supported for years after launch, not just shipped.
Full security hardware ranges
Whole ranges built under one roof, so mechanical and connected products in the same line share a keying system and a finish.
The images above are renderings used to illustrate the product categories we build. They do not represent a specific product developed for a client.
These are the categories we build most often, not a catalogue.
Lock designs get copied, which is why this category sits inside a facility built around IP protection: black-box workflows, supplier isolation, and no single vendor holding your complete mechanism.
Proven work
Key projects: Padlocks, bicycle locks, electronic door locks.
Britain’s long-established high-security lockmaker. Across a 12-year C2W Group relationship, we provide product sourcing, custom product development, production management, and quality control, holding their locks to rigorous safety and durability standards for global markets.
Our Development Process
Share your concept, materials, target market, and production goals. We sign an NDA before specifics are discussed, then assess feasibility and the best path forward.
A structured manufacturing roadmap for your product: key stages, estimated costs, and production timelines, agreed before tooling money is committed.
Engineering files refined into physical prototypes, iterated until materials, function, and durability are proven rather than assumed.
Bill of materials, tolerances, and assembly workflows finalised for repeatable production, eliminating manufacturing problems on paper rather than on the line.
A pilot batch verifies every component against specification before full production. Multi-supplier sourcing means no single supplier ever sees the complete design.
Every batch is inspected against your agreed criteria, then packed, consolidated, and shipped from our own warehouse, in secure custody until it leaves for your market.
Certifications
Shield Works is independently certified across three management systems: Quality (ISO 9001), Environmental (ISO 14001), and Occupational Health & Safety (ISO 45001). Also audited annually under SEDEX SMETA, an independent ethical-trade audit covering labour, health and safety, environment, and business ethics.

Frequently Asked
Because the product is the secret. Anyone who sees the full mechanism, the keying system, or the firmware can compromise it. At Shield Works, operators only see their assigned task, suppliers only receive the data their component requires, and the complete product is integrated in-house under fingerprint-access control. See the full IP protection model.
Yes. Precision mechanical work runs alongside a dedicated ESD-controlled electronics room, so traditional cylinders and smart, app-connected locks are built under one roof with one quality regime.
Cycle testing, force and tamper resistance, corrosion and ingress testing, and dimensional verification against your specification, plus independent batch verification by a C2W Group quality engineer. More on quality inspection and testing.
Yes. NDAs are signed before any technical discussion, and the agreements are binding, signed with a British-owned and managed company. Staff and supplier contracting includes confidentiality obligations, with documented, audit-ready controls.
We do not run a fixed minimum order quantity, but projects typically start from USD 10,000 in order value.
Yes. We transition existing lines into our facility regularly, including re-tooling, process improvements, and design updates, with confidentiality maintained throughout the transfer.
We look at your product and requirements, assess fit, and reply to most enquiries within 24 hours. If it looks like a fit, we review the project in detail and issue an NDA where needed, then set up a call to confirm fit before we come back with a proposal. All work runs under a paid engagement. Submit your project brief.
A lock or a strongbox is judged the one time somebody attacks it, and that is a poor moment to discover a material substitution. Specification control, supplier verification and batch traceability are the whole job in this category.
