What information do I need when I call a locksmith?

Have your location address, type of lock issue (house, car, or business), and proof of ownership or residency ready. For car lockouts, know your vehicle make, model, and year. This helps us dispatch the right technician with the right tools.

Will unlocking my car damage the vehicle?

No. Our technicians use specialized non-destructive tools designed for safe vehicle entry. We guarantee no damage to your car's paint, weather stripping, window mechanisms, or lock systems. Learn more about our car lockout service.

What should I do if my key breaks in the lock?

Don't try to remove the broken key yourself — this can push it deeper and cause more damage. Call us immediately and our technicians will use specialized extraction tools to safely remove the broken piece without damaging your lock.

Can you rekey locks to match existing keys?

Yes. We can rekey multiple locks throughout your home or business to work with a single key. This is a popular and cost-effective option after moving into a new home — it ensures previous keys no longer work without replacing the hardware.

What's the difference between rekeying and replacing locks?

Rekeying changes the internal pins so old keys won't work, but keeps your existing hardware — it's faster and more affordable. Replacing locks gives you completely new hardware with updated security features. We recommend the best option based on the condition of your locks and your budget.

Do you install smart locks for older homes?

Yes. We retrofit smart locks to older homes throughout the St. Louis metro. We assess your existing door hardware, recommend compatible systems, and handle the full installation and setup — including connecting to your phone or home network.

Are you licensed and insured?

Yes. We are fully insured and bonded in Missouri and Illinois. All technicians are background-checked professionals. We've been in business since 2010 with over 500 five-star reviews.

Do I need proof of ownership?

Yes. For security purposes, we require proof of ownership or residency for lockout services. A driver's license, utility bill, rental agreement, or vehicle registration all work. This protects you and ensures we're only helping authorized people gain entry.

What areas do you serve?

We serve 40 cities across the St. Louis metropolitan area in both Missouri and Illinois. Our coverage includes Saint Louis, Maplewood, Clayton, Kirkwood, Chesterfield, Ballwin, Florissant, St. Charles, Belleville, Edwardsville, and 30 more communities. We dispatch mobile units to your location.
