About Us
About Capital Lock, Inc.
Capital Lock, Inc. is a commercial locksmith and door-hardware company located at 1302 Regent Street in Madison, Wisconsin. We serve businesses, institutions, property managers, contractors, and homeowners throughout Madison and southern Wisconsin.
Officially founded in 1997, Capital Lock’s roots in the Madison locksmith industry date back to 1978. Today, our team provides keys, locks, safes, commercial door hardware, master key systems, installation, repair, rekeying, preventative maintenance, and mobile locksmith service.
Our History
Capital Lock’s history began with Gordon DeVries’ work in the Madison locksmith industry in 1978. Capital Security Systems was founded in 1981 as a locksmith business and later expanded into alarm systems and patrol and guard services.
After Capital Security Systems was bought out in 1997, the locksmith portion of the business was sold back to former managers Mike Stilwell and David Koenig. They established Capital Lock, Inc. that same year and continued serving customers from Madison’s Regent Street corridor.
Bryce Clark purchased David Koenig’s ownership interest in January 2021. In January 2022, Alex Mickelson, Bryce’s longtime friend from high school and college, purchased Mike Stilwell’s ownership interest.
Under the current ownership team, Capital Lock has grown from six employees to ten while continuing to expand its commercial locksmith, door-hardware, safe, repair, maintenance, and mobile-service capabilities.
