Locksmith Service Across North County’s Largest Suburb

Locks R Us Locksmith provides mobile locksmith service throughout Florissant, from the old streets around rue St. Francois to the post-war subdivisions off New Halls Ferry Road and the businesses along Lindbergh Boulevard. We help homeowners, landlords, tenants and businesses with lockouts, rekeying, lock repair, lock replacement and new lock installation. If you are standing outside a door right now, start with our urgent lockout response.

Because our service is mobile, we come to the property rather than asking you to visit a storefront. Call (636) 628-7803 with the address, whether the property is a home or a business, and what the lock or door is doing. We are open daily from 8 AM to 10 PM.

Two Hundred Years of Doors in One City

Florissant is unusually mixed for a suburb. Old Town still follows the street plan laid out under Spanish rule, and the buildings around it go back to the 1819 convent and 1821 church at Old St. Ferdinand Shrine. A mile away sit the subdivisions that went up in the great North County building boom, street after street of them, each built at the same time to the same specification.

That produces two entirely different jobs. On the older properties we are working around hardware that deserves keeping, where repair and adjustment usually beat replacement. On the boom-era streets the locks are all the same age, so when one starts sticking the neighbours’ are not far behind, and replacing worn hardware across a house at once often makes better sense than doing it a door at a time. Mobile service covers Florissant ZIP codes 63031, 63033 and 63034.

What We Do in Florissant

Home Lockouts and Entry Assistance

Locked out of a Florissant house or apartment? Call with the address and the type of lock. We provide mobile entry assistance and explain the approach before starting, aiming to open the door carefully rather than replacing hardware that did nothing wrong. More on emergency lockout service.

Key Control for Rentals and Moves

Florissant has a lot of rental property, and the most common reason we are called is simple: nobody is sure how many keys are still out there. A lock can look perfect while old keys still turn it. Where the hardware is compatible and sound, changing which key works solves that without replacing a single lock body.

Lock Changes and Replacement

When hardware is worn through, damaged, or was never much of a lock to begin with, replacement is the honest answer. We check the door, backset and bore before recommending anything so the new lock fits the door it is going on. More on residential lock changes.

Lock Repair and Door Alignment

A deadbolt that binds, a latch that misses the strike, or a cylinder that has gone loose may be a lock fault or a door fault, and the fix is very different depending on which. We look at both together. More on lock repair and installation.

Commercial and Managed Property Work

Offices, storefronts and managed buildings along Lindbergh and New Halls Ferry need work done without stopping the day. We handle commercial rekeying, lock repair, hardware replacement and key control. Tell us how many entrances are involved and which are main, office or back doors, since they take different traffic and different hardware. More on commercial locksmith service.

Smart Lock Installation and Setup

Keypad and smart locks suit some doors and not others. We check thickness, backset and bore before anything is bought, then install and set up compatible hardware. They are a good fit for rentals, where codes can be changed without cutting keys. More on smart lock installation.

What Florissant Jobs Usually Involve

Most Florissant calls come down to one of two things: keys that are no longer accounted for, or hardware that has quietly worn out after decades of daily use. The first is cheap to fix and worth doing the week you move in or the week a tenant hands the keys back. The second is worth catching before the door stops closing altogether.

North County work rarely stops at the Florissant line. We take the same calls just south in Ferguson, cover homes and warehouses on the Hazelwood side, and cross the river regularly for customers in St. Charles and their neighbours in St. Peters. Our base sits west of here in Ballwin, so call early in the day when you can. Everywhere we reach is listed on our areas index.

We are mobile, so there is no Florissant storefront to visit — we come to the property. Our technicians are licensed and insured. Vehicle work is unlocking only: no key cutting, no fob or remote programming, no ignition work. Open every day, 8 AM to 10 PM.
