A business lockout costs money by the minute: staff waiting in the parking lot, customers turned away, deliveries that can’t be signed for. Prime Locksmith Services opens storefronts, offices, warehouses and suites across St. Louis, and works on the commercial hardware that a residential locksmith often can’t: mortise locks, aluminum storefront doors, exit devices and high-security cylinders.
Once you are back inside, we can rekey the locks if a key walked out with a former employee, replace damaged hardware, or set up a master key system so it doesn’t happen again.
For commercial lockout service in St. Louis or any job for a commercial locksmith in St. Louis, call (314) 745-4590.
Fast, professional and documented.
Business address, the door and lock type, and whether keys are lost or locked inside.
We quote on the phone, priced per lock cylinder.
Photo ID plus proof you can authorize entry: a lease, business license, or a call to the owner or property manager.
Non-destructive entry wherever possible, on storefront, mortise and standard commercial locks.
Rekey, replace or repair on the same visit, with an itemized receipt for your records.
If a lockout follows an employee leaving, or keys are unaccounted for, rekey the affected locks right away. With a master key system you can rekey one door without changing keys for the whole building. See lock rekeying.
