Master Lock

What Master Lock does

Master Lock Company LLC is a U.S.-based physical security hardware manufacturer founded in 1920, headquartered in Oak Creek, Wisconsin, and operating as a wholly-owned subsidiary of Fortune Brands Innovations, Inc. (NYSE: FBIN). The company produces a diversified portfolio of more than 2,000 SKUs spanning padlocks (laminated, solid body, combination), Bluetooth-enabled smart locks, lock boxes, safes, door hardware, chain and cable locks, U-locks, and a comprehensive lockout tagout (LOTO) product line designed to meet OSHA industrial safety requirements. Sister brands American Lock (high-security industrial padlocks) and SentrySafe (fire and security safes) extend the portfolio under the Fortune Brands umbrella.

The company's technology stack combines mechanical locking hardware with proprietary features such as BlockGuard Anti-Shim Technology, Weather Tough sealing, and Push to Lock mechanisms, alongside connected offerings including the Master Lock Vault software platform for centralized access management and cLOTO for computerized lockout tagout procedure management. Bluetooth-enabled padlocks, lock boxes, and built-in locker locks pair with mobile applications to provide real-time access logging, credential issuance, and revocation.

Master Lock's business model is anchored in unit-based hardware sales rather than subscriptions. Pricing ranges from approximately $7.99 for entry-level combination locks to over $450 for commercial lockout tagout kits, with no recurring fees on the majority of products. Go-to-market combines direct e-commerce (store.masterlock.com), a dedicated B2B distributor portal (masterlockshop.com), retail and wholesale partners, and online marketplaces, serving both individual consumers and institutional buyers across schools, industrial facilities, transportation operators, and real estate property managers. Customization services (laser engraving, colored dials, custom keying) and global operations (including a French-language site) support multi-segment revenue capture.
