King Locksmith And Doors Inc. supplies manufacturer-original parts from Schlage, Kwikset, Baldwin, Yale, Medeco, and other industry-leading brands verified authentic, expertly identified, and trusted by the professionals who keep doors working.
For decades, the performance of a door has depended on the integrity of what’s inside it. A lock is only as reliable as the cylinder, latch, spring cage, or spindle it was engineered around and only genuine, manufacturer-original parts preserve that engineering. King Locksmith And Doors Inc. exists for one purpose: to be the definitive source for authentic door hardware parts from the brands that define this industry.
Every part King Locksmiths carries is genuine, sourced through authorized channels, and traceable to its original manufacturer. We do not stock imitation components, gray-market imports, or reverse-engineered substitutes. When a locksmith rebuilds a mortise lock or a facility manager services three hundred openings, the difference between an original part and a lookalike is measured in tolerances of thousandths of an inch and in years of service life.
This is why institutions, security professionals, and hardware distributors rely on genuine parts: they carry the manufacturer’s specifications, metallurgy, and finish standards. They preserve fire ratings, ANSI/BHMA grade certifications, and warranty coverage. Substitutes do not.
Unsure whether a part is manufacturer-original? Send us the series, markings, or a photo. King Locksmiths will confirm authenticity and identify the correct genuine component.

Our customers are the people responsible for doors that must work every time: Goverment facilities, property management firms, healthcare and education facility teams, and independent hardware distributors. They come to us because identifying the correct part; the right cam, the correct tailpiece length, the proper handing requires brand-level expertise, and because their reputations depend on installing components that meet the original specification.
That expertise is the foundation of this resource. The King Locksmiths team works from manufacturer parts breakdowns, service manuals, and decades of field experience across every major product line, the same knowledge our technicians apply on lock and door work every day. If a lock series was produced in the last fifty years, our objective is to help you identify it, source its genuine components, and return it to factory condition.
The economics of door hardware favor authenticity. A genuine replacement part typically costs a fraction of full hardware replacement while restoring the original performance grade. Counterfeit and will-fit parts, by contrast, introduce failure points that surface at the worst possible time, a binding latch on a fire door, a stripped spindle on a high-traffic entrance, a compromised keyway in a controlled facility. In life-safety and security applications, non-genuine components can also void listings and certifications that buildings are required to maintain.
Sourcing genuine parts is therefore not a premium choice. It is the baseline standard of professional door hardware maintenance and it is the only standard we operate to.
Before replacing hardware outright, find out what a genuine-parts repair costs. Send your lock’s details and we’ll quote the exact components that restore factory performance.
Door hardware is one of the most heavily regulated categories in the built environment, and genuine parts are what keep an opening compliant. Four frameworks govern nearly everything we supply. When you source through King Locksmiths, you are sourcing components that keep every one of these certifications intact.
The grading system for durability, security, and finish. A Grade 1 lockset earns that rating as a complete assembly; only manufacturer-original components preserve it through repair.
Underwriters Laboratories certifications, including UL 10C for fire-rated door hardware and UL 437 for high-security cylinders. A UL-listed device serviced with non-listed parts is no longer a listed device.
The National Fire Protection Association's standard for fire doors, which requires that repairs maintain the assembly's original label. Genuine parts are how field repairs stay within the listing.
Accessibility requirements governing operable hardware, opening force, and lever operation. Correct genuine levers, trim, and closers keep an opening accessible and code-compliant.
Our name goes on every part we supply, so our commitment is straightforward:
Genuine, always. Every component is manufacturer-original and sourced through legitimate channels. no exceptions, no substitutions without your knowledge.
Accurate identification. We confirm series, finish, handing, and function before anything ships, because the right part the first time is the only acceptable outcome.
Straight answers. If a part is discontinued, backordered, or better replaced by a current-production equivalent, we tell you plainly and document the alternative.
Accountable expertise. The same technicians who install and service this hardware in the field stand behind the guidance on these pages.
