Codelocks was started by Dorothea and Desmond Ryan, Codelocks’ chairman, out of their small fourth-floor apartment in central London in 1991 with the goal to satisfy the unmet need for a simple digital lock in the marketplace. After much research, they sourced a digital lock from Taiwan, and Codelocks was born with its first and still available lock: the mechanical CL250.
It looks like the company was founded in London, then later set up international branches, FWIW.
