About Nonstop Lock & Key

Nonstop Lock & Key was founded with a simple idea: when someone in St. Louis is locked out of their home, car, or business, they deserve fast, honest help — not inflated prices or long wait times. As a locally owned and operated mobile locksmith company, we take pride in treating every customer like a neighbor, because in most cases, they are.

We are fully licensed and insured in the state of Missouri, and every job we take on is backed by professional-grade tools, up-to-date training, and a genuine commitment to doing things right the first time. From our base in Creve Coeur, our mobile units serve more than 20 cities across the greater St. Louis area, bringing full-service locksmith capabilities directly to your door — whether that is a residential home in Florissant, a commercial storefront in Clayton, or a roadside lockout on I-270.

What started as a one-person operation has grown into a trusted name across the metro, with over 100 five-star reviews from real customers. We cover residential, commercial, and automotive locksmith needs 24 hours a day, 7 days a week — including holidays and weekends. When you call Nonstop Lock & Key, you are not getting a national call center. You are getting a real local locksmith who knows St. Louis and will be at your location fast.
