The Master Lock Company is dedicated to empowering people to live safer, more secure lives. We have built trust with individuals and businesses by delivering strong, reliable solutions that protect valued assets and safeguard lives. We are proud of our long history as a trusted partner to our dedicated locksmith and security hardware customers.
Our pioneering founders, John Junkunc and Harry Soref, inventors and engineers, introduced many firsts to the industry: precision-machined, solid-body padlocks and laminated padlocks, ball-locking shackles, serviceable padlocks, and even the dial combination lock. These innovative solutions built our iconic brands – American Lock® and Master Lock® – and represent our full suite of products specifically designed to deliver the quality, durability and superior security that suit commercial and residential requirements.
Today, we carry forward their spirit of identifying customer needs and developing new products based on insights and research. We blend our industry findings with feedback from our locksmith partners to deliver enhanced solutions to you, our valued customers.
