Called Alex on a Saturday morning about my Civic. Out the door in less than half an hour. Easy.

Bought a fixer-upper and wanted everything rekeyed before the kids moved in. Alex came same day, did 5 doors in under an hour, and even fixed a loose strike plate that was on the way to giving up. Honest pricing all the way through.

Spare key for my Subaru Outback. Took it to a mechanic first and they said they couldn't help. Called Nonstop and Alex met me at the office, cut and programmed the key in like 25 minutes. Wish I'd called them first instead of running around.

I run a small dental practice and after a staff change I needed everything rekeyed plus a smart lock with shared codes for the team. Alex walked me through the smart lock options without pushing the priciest one and made sure the codes were set up the way a HIPAA-conscious office needs. Did the rekey on five other doors in the same visit. The whole thing felt like working with a friend instead of a vendor. Will be calling them anytime we need anything lock-related.

My only spare key snapped in the door. Less than 30 min to get a tech to me, broken piece out, lock still working. Real life saver.

Bought a Schlage Encode for our front door but didn't trust myself to install it right. Nonstop sent Alex out, he had it mounted and paired with our wifi in maybe 40 minutes, and set up a code for our cleaning service. Stayed long enough to make sure my wife was comfortable using the app too. Above and beyond.

Got home from a trip and my house key wouldn't turn in the lock. Was panicked because my flight had been delayed and i was exhausted. Nonstop picked up right away, Alex was at my door fast, opened it without damage, and showed me my deadbolt just needed a bit of lubrication. Charged for the visit only, didn't try to sell me a new lock. Honest service is rare.

Locked my keys in my Tahoe at the grocery store. Quick response, no scratches, no surprise fees. Will use again.
