DOYLE LOCK SUPPLY, INC.

Doyle Lock Supply, Inc. specializes in the manufacturing and supply of high-security hardware components for federal applications, with core expertise in precision lock systems, key blanks, and related mechanical access control products. The company delivers compliant, durable hardware solutions tailored to government specifications, including American 6-pin tumbler key blanks and federally standardized locking mechanisms. Their technical proficiency lies in metallurgical fabrication, dimensional precision manufacturing, and adherence to federal supply standards for physical security equipment. A key differentiator is their ability to produce certified, repeatable components that meet stringent federal interchangeability and durability requirements, ensuring seamless integration into existing government infrastructure systems. The contractor maintains a consistent relationship with the General Services Administration, supplying standardized hardware under Federal Supply Schedule contracts, and has delivered critical locking components to the Department of Justice, indicating direct support for law enforcement and correctional facility security needs. These engagements reflect a pattern of reliable, low-profile procurement support for physical security infrastructure rather than large-scale system integration. Doyle Lock Supply operates primarily within NAICS 332510 (Hardware Manufacturing) and 334290 (Other Communications Equipment Manufacturing), focusing on mechanical access control devices rather than electronic systems. Their market positioning is as a niche supplier of mission-critical physical security hardware, serving federal agencies that require robust, non-electronic locking solutions with strict compliance and traceability. As a small business structured as a 2L entity based in Minneapolis, Minnesota, Doyle Lock Supply operates without federal certifications such as 8(a), HUBZone, or WOSB. Their geographic presence is centered in the Upper Midwest, with a focused government market role as a trusted provider of standardized, high-integrity hardware components for federal procurement channels.
