Michael T.
Clayton, MO
"Locked out of my condo on Forsyth at 2am after losing my keys at dinner. Called Nonstop Lock & Key and they had a technician at my door in under 20 minutes on a Saturday night. He opened the deadbolt without a single mark on the door, then rekeyed it on the spot so the lost keys wouldn't work. Exactly the service you want in a stressful moment."
Sarah M.
University City, MO
"Had all the locks rekeyed after closing on our house in University City. The technician arrived on time, rekeyed five exterior doors in about two hours, and set everything to work with a single key. He even tightened a loose strike plate he noticed on the back door. Fair pricing and thorough work."
David C.
Chesterfield, MO
"Lost my only car key at Chesterfield Mall and was stranded in the parking lot. Nonstop Lock & Key came out, cut a new transponder key, and programmed it to start the engine — all in the parking lot in about 40 minutes. Saved me from an expensive tow to the dealership."
Jennifer W.
Webster Groves, MO
"Had Nonstop install a Schlage Encode smart lock on our front door in Webster Groves. The technician handled the installation cleanly, set up the app on both our phones, and programmed guest codes for the dog walker. Very knowledgeable about the different smart lock brands and helped us choose the right one."
Jason P.
Kirkwood, MO
"Broken key snapped off in our front door lock at 11pm on a weeknight in Kirkwood. Called Nonstop and the locksmith arrived in about 25 minutes. He extracted the broken piece, tested the cylinder, and determined the lock was still in good shape. Quick, professional, and the price matched the quote exactly."
Angela R.
Ballwin, MO
"Locked my keys in the car with the engine running outside the grocery store on Manchester Road in Ballwin. Called in a panic and they treated it as a priority. Technician arrived in under 30 minutes and had the door open in two minutes flat. No damage to the car at all. Highly recommend."
