Most people do not think about locksmith work until they actually need it, and that is usually when experience matters most.
Our work is built on long term relationships in the community, which is why so much of what we do comes from repeat customers and referrals.

Family Owned and Operated for Decades

In the 35+ years that Kevin and Marti Grubb have owned the shop, we continue to be known for consistent service and long-term customer relationships.

Experienced, Background Checked Locksmiths
Our locksmiths have over a century of combined experience working on residential properties across the St. Louis area.
Every technician is background checked, bonded, and insured, and has hands-on experience with a wide range of home hardware. This includes older and more complex systems found in many local homes, such as mortise locks and antique door hardware.
Our depth of experience helps us handle both standard and specialized work with confidence.

Brick & Mortar Store
Unlike many locksmiths who only work out of a service vehicle, we have a storefront where you can get help in person. Our clients can stop by our shop to bring in locks or keys instead of scheduling a service call.
This is especially useful for things like key cutting or lock repairs, and it can help reduce service costs when on-site work is not needed. Our team is available in-store to answer questions and help you find the right solution.
