15 March 2026Just closed on our house in U City and wanted everything rekeyed for peace of mind. Nonstop Lock & Key sent Alex out same day. Did 5 exterior doors in about 90 minutes and even fixed a sticky strike plate on the back door. No surprise fees, paid exactly what was quoted.

28 February 2026Lost my only Honda key at the mall on a Sunday. Dealership wanted $500+ PLUS a tow. Nonstop came to the parking lot, Alex cut a new transponder, programmed it, and I was driving home in under an hour!!! Saved me SO much money, can't recommend enough 🔑

19 February 2026Needed a spare fob for my Toyota Camry. Took it to the dealer first and they wanted wayyy too much. Nonstop did the same thing for HALF the price at my apartment complex. Tech was super friendly and walked me through the whole programming process 👌

8 February 2026My ignition started sticking and eventually wouldn't turn at all. A mechanic told me it was an electrical issue and quoted me a fortune. Alex from Nonstop diagnosed it as a worn ignition cylinder in 10 minutes and replaced it the same day for way less.

25 January 2026Wanted to upgrade all the locks at our new house to a higher security grade. Nonstop walked me through the options (didn't push the most expensive), installed everything in one afternoon. Doors look better than they did before.
Jennifer W.
12 January 2026Had Nonstop Lock & Key install a Schlage Encode smart lock on our front door. Alex walked us through the app, set up codes for the dog walker, and even paired it with our Ring system. Patient and knew the differences between like 4 brands of smart locks.

30 December 2025Inherited an old fire safe from my dad without the combo 🤷 Called around and most places quoted insane prices or said they don't even DO safes. Nonstop came out, got it open without damage in like 20 min, then rekeyed it for me. Saved my whole afternoon, great service
