A smart lock lets you open the door with a code, your phone or a fingerprint, give a dog walker a code that only works on weekdays, and check from work that the door is locked. It only works that well when the lock fits the door, the bolt throws cleanly and the app is set up correctly. Prime Locksmith Services installs and configures smart locks for homes, rentals and small businesses across St. Louis.
We install keypad deadbolts, Wi-Fi and Bluetooth smart locks and smart lever sets, adjust the door so the motor isn’t straining, and walk you through codes and the app before we leave. Your lock keeps a physical key backup, which we can key to match your other doors.
For smart lock installation in St. Louis or any job for a residential locksmith in St. Louis, call (314) 745-4590.
We handle the fiddly parts so the lock works from day one.
Codes, app, fingerprint or voice assistant. We help you choose, or install the lock you bought.
Bore size, backset and door thickness all have to suit the lock.

Smart locks run on batteries. Most warn you for weeks before they die, but keep the physical backup key somewhere you can reach from outside the house, or choose a model with emergency battery contacts on the keypad.
