Locksmith Service Between Mid Rivers and Old Town
Locks R Us Locksmith provides mobile locksmith service throughout St. Peters, from the shops and offices along Mid Rivers Mall Drive to the subdivisions off Spencer Road, Jungermann Road and Mexico Road. 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.
Our service is mobile, so 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, and same-day service is often available.
Streets Where Every Lock Is the Same Age
Most of St. Peters went up in a few decades of steady building, which makes it an unusually predictable place to work. Whole streets were finished in the same year by the same builder, with the same hardware on every front door. When one house calls us about a deadbolt that has started to stick, the neighbours are usually within a year or two of the same problem.
That has a practical upside. On a house where the locks all went in together and have all worn together, doing the exterior doors in one visit costs less than replacing them one at a time over three years. Around Old Town and the older pockets near the parish church the picture is different, and there repair and adjustment often beat replacement. Mobile service covers ZIP code 63376 and the parts of 63304 that fall inside the city.
What We Do in St. Peters
Home Lockouts and Entry Assistance
Locked out of a St. Peters house or apartment? Call with the address and the type of lock. We explain the approach before starting and aim to open the door carefully rather than replacing hardware that did nothing wrong. More on emergency lockout service.
Rekeying After a Move or a Tenant Change
Nobody moving into a resale house knows how many keys are still out there, and a lock can look perfect while old keys still turn it. Where the existing hardware is compatible and sound, changing which key works retires every old key without replacing a single lock body. It is the first thing worth doing the week you get the keys.
Lock Changes and Replacement
When hardware is worn through, damaged, or was builder-grade to begin with, replacement is the honest answer. We check the door, backset and bore first so the new lock suits the door it is going on, and we can key the exterior doors alike if you want one key for the house. 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 rather than replacing a lock that was never the problem.
Commercial and Managed Property Work
Shops, offices and managed buildings along the Mid Rivers corridor and Cave Springs need the work done without closing for 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 the newer housing here well, but they do not fit every door. We check thickness, backset and bore before anything is bought, then install and set up compatible hardware. They work particularly well on rentals, where a code can be changed without cutting a key. More on smart lock installation.

What St. Peters Jobs Usually Involve
Two calls come in more than any others: keys that are no longer accounted for after a sale or a tenancy, and hardware that has quietly worn out after decades of daily use on the same door. The first is cheap to fix and worth doing straight away. The second is worth catching before the door stops latching altogether, usually in winter when a stiff lock finally gives up.
Work here rarely stops at the city line. We take the same calls east in St. Charles, west in O’Fallon, and out towards Lake St. Louis and Wentzville. Our base sits south of the river in Ballwin, so call earlier in the day when the job can wait. Everywhere we reach is listed on our areas index.
We are mobile, so there is no St. Peters storefront to visit – we come to the property. Our technicians are licensed and insured, with more than ten years of local work behind them. Vehicle work is unlocking only: no key cutting, no fob or remote programming, no ignition work. Open every day, 8 AM to 10 PM.
St. Peters Locksmith Questions
I have just bought a house in St. Peters. What should I do about the locks?
Rekey them, in almost every case. On a resale house there is no way to know how many keys exist or who still has one, and where the locks are compatible and serviceable we change which key operates them so every old key stops working. No lock is replaced, so it costs a fraction of new hardware and takes one visit.
My deadbolt has become stiff and my neighbour says theirs has too. Why?
Because they are the same age. Whole streets here were built at once with identical hardware, so locks tend to wear out on the same schedule. It is worth having all the exterior doors looked at in one visit rather than paying for a separate call every time another one starts sticking.
Do you cover all of St. Peters, and what are your hours?
Yes – ZIP code 63376 and the part of 63304 inside the city, from Old Town and Mexico Road out to the Mid Rivers corridor and Cave Springs. We are open daily from 8 AM to 10 PM. Call (636) 628-7803 with the exact address to confirm current availability.
Can you get here today?
Often, yes. We are based in Ballwin, so St. Peters is a run across the river rather than a local call. Same-day service is frequently available, particularly if you ring earlier in the day. Tell us what has happened and we will give you an honest answer on timing rather than a number that sounds good.
