What St. Louis Customers Say
Real reviews from real St. Louis customers. Read honest feedback about our locksmith services.
I manage a 24-unit apartment building in the Central West End, and when our property manager left, we had to rekey every unit plus the common areas. A1 Express sent two technicians and knocked out the entire job in one day. They set up a brand new master key system that makes my life so much easier. The invoice was detailed and transparent.
We just bought a 1920s bungalow in Tower Grove and needed every lock changed before moving in with our two kids. The technician took one look at the old mortise locks and knew exactly what hardware would work. He installed Schlage deadbolts on all exterior doors, rekeyed the garage, and even fixed a sticky interior door latch. Clean, polite, and incredibly knowledgeable.
I lost my key fob for my 2021 Toyota Camry while running errands near Washington University. The dealership told me it would be $400 and I would have to tow the car in. A1 Express came to the Delmar Loop parking lot where I was stuck, cut a new key, and programmed the transponder chip right there in their van. Total cost was less than half the dealer quote.
