I needed my house locks rekeyed after moving in, and the technician explained everything clearly before starting the work. Everything was done neatly and efficiently. I feel much safer now thanks to John Locksmith of St. Louis!

The physical location doesn’t exist. GPS is showing it next to the Aldi, but that’s not accurate. Please update your address…

Not just a locksmith — a lifesaver. I locked myself out of my car on a freezing morning in St. Louis. I called John, and within 20 minutes he was there, calm and kind. He didn’t rush or overcharge — he just helped. It’s rare these days to find people who treat you like a human and not a transaction.
Sara Magalli
Shady business practice: was told a $29.99 service fee over the phone, and that ended up being $500. He charged $189 for emergency call, $120 for service, $30 for travel, and $80 for like, additional service, and then $70 for tax. Then he kept asking for cash. I was in no position to drag on the process and try to make it all reasonable, so I just paid and moved on with my day. Don’t use them.
