Master Lock Security Products

Master Lock is an iconic American brand that has become synonymous with padlocks and security solutions. Founded in 1921 by Harry Soref in Milwaukee, Wisconsin, the company revolutionized the industry with the invention of the laminated steel padlock, designed to be as strong as a bank vault door.

Today, Master Lock operates as a global leader in security. While its historical roots and headquarters remain in the United States, most manufacturing shifted from Milwaukee to facilities in Mexico and China during the late 20th and early 21st centuries to maintain global competitiveness. The brand is known for a wide array of products, from traditional high-security padlocks to modern digital and Bluetooth-enabled smart locks.

Master Lock is currently the flagship brand of Fortune Brands Innovations. It was previously part of the Fortune Brands Home & Security spin-off before the company rebranded to focus on digital and smart home innovations. The brand maintains a dominant market share in North America and continues to expand its technological footprint in the security sector.
