Locksmith Service Across the River in St. Charles

Locks R Us Locksmith provides mobile locksmith service throughout St. Charles, from the brick storefronts on historic Main Street and the old houses of Frenchtown to the newer subdivisions west of the city and the businesses along First Capitol Drive and Highway 370. We help homeowners, landlords and businesses with lockouts, rekeying, lock repair, lock replacement and new lock installation. Locked out 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 it is a home or a business, and what the lock or door is doing. We are open daily from 8 AM to 10 PM.

The Oldest Doors We Work On

St. Charles was founded in 1769, and Main Street has the buildings to prove it. The historic district and Frenchtown hold some of the oldest working doors in the region, and they come with the problems that age brings: mortise locks rather than the cylindrical deadbolts on modern houses, hardware that has been in service longer than anyone remembers, and doors that have been rehung, repainted and adjusted by a dozen owners.

Then, ten minutes west, there are subdivisions built in the last thirty years with standard hardware and standard doors. We work on both, and the approach is different. On the historic side the aim is usually to keep what is there working, since matching original hardware is difficult and replacing it outright is rarely what an owner wants. On the newer side it is straightforward rekeying and replacement. Mobile service covers St. Charles ZIP codes 63301, 63303 and 63304.

What We Do in St. Charles

Home Lockouts and Entry Assistance

Locked out of a St. Charles house or apartment? Call with the address and the type of lock, and say whether anyone is inside. On older properties we take particular care, because forcing an antique lock creates a much larger problem than the one you started with. More on emergency lockout service.

Working With Historic Hardware

Mortise locks and period hardware on Main Street and in Frenchtown can often be serviced rather than replaced. Send a photo of the door edge and the lock face before anything is ordered and we will tell you what can be repaired, what can be matched, and what genuinely has to go. More on lock repair and installation.

Rekeying After a Move or a Tenant Change

Where the hardware is compatible and sound, rekeying changes which key operates it and retires every old key without replacing a single lock. It is the usual answer after a purchase, a tenancy ending, or any doubt about how many keys exist. More on rekeying.

Lock Changes and Replacement

On the newer side of the city, replacement is straightforward: we check the door, backset and bore and fit compatible hardware, matching the other doors where you want one key throughout. More on residential lock changes.

Commercial Work on Main Street and First Capitol

Main Street runs on visitors, so shutting a shop door for an afternoon costs real money. Tell us when the entrance has its lowest traffic and we will work to that. We handle commercial rekeying, lock repair, hardware replacement and key control for shops, restaurants, offices and managed buildings. More on commercial locksmith service.

Smart Lock Installation and Setup

Smart and keypad locks suit the newer housing well. On a historic door they often do not fit at all without cutting into something worth keeping, which is worth knowing before you buy rather than after. We check compatibility first. More on smart lock installation.

What St. Charles Jobs Usually Involve

St. Charles is across the river from us, so it is a longer run than our western towns. That is worth knowing when you plan: if the job can wait, calling earlier in the day gives us a better chance of reaching you the same day. If it cannot wait, call anyway and we will tell you honestly what the timing looks like.

The most useful thing you can tell us here is how old the property is. A 1990s house in the west of the city and an 1840s building on Main Street are different jobs needing different parts, and knowing which we are coming to saves a return trip. We also cover St. Peters and O’Fallon on the same side of the river; everywhere we reach is on our areas index.

We are mobile and based in Ballwin, so there is no St. Charles storefront to visit — we come to the property. Our technicians are licensed and insured. Vehicle work is unlocking only: we do not cut or replace car keys, program transponders, fobs or remotes, or work on ignitions. Open every day, 8 AM to 10 PM.
