Mobile Locksmith Service for Union and Franklin County
Locks R Us Locksmith covers Union, the seat of Franklin County, along with the properties spread out around it on Highway 50 and Highway 47. We help homeowners, farms, landlords and businesses with lockouts, rekeying, lock repair, lock replacement, new lock installation and master key systems. 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 Far End of Our Coverage, and What That Means
Union is in our Franklin County coverage area, and it is a long way west of our Ballwin base. Timing varies with distance, I-44 traffic, weather, technician availability and the calls already booked that day. Call for a current arrival estimate before dispatch rather than assuming, and if the job can wait, earlier in the day is always better.
The distance also changes what makes sense to do in one visit. On a property out here it is usually worth dealing with everything at once — the sticking back door, the outbuilding nobody has a key for, the spare that never worked properly — rather than booking us out twice. Tell us the whole list when you call and we will come prepared for it. Mobile service covers Union ZIP code 63084.
What We Do in Union
Home Lockouts and Entry Assistance
Lost your keys, left them inside, or the lock has stopped working? Call with the address and the type of lock, and say whether anyone is inside. We explain the approach before starting and work to open the door without damaging hardware that is doing its job. More on emergency lockout service.
Lock Rekeying
Need the locks changed without replacing them? Where the hardware is compatible and sound, rekeying changes which key operates it — after moving in, after losing a key, or when you want to restrict who can get in. Residential and commercial both. More on rekeying.
Master Key Systems
For a business, a rental property or a building where different people need different access, a master key system means one key for you and limited keys for everyone else. It needs planning around who should reach what, which is a conversation worth having before any hardware is bought. More on commercial locksmith service.
Lock and Hardware Repair
Sticking keys, loose cylinders, a latch that misses the strike, door hardware that has worked loose — these are often the door rather than the lock, and the two cost very different amounts to put right. We check both. More on lock repair and installation.
Lock Replacement and Installation
Where hardware is worn out, damaged or weaker than you want, we fit a compatible replacement, checking the door, backset and bore first. More on residential lock changes, or smart lock installation if you are considering a keypad.

Local Landmarks We Work Near
- The Franklin County Courthouse — Union is the county seat, and the courthouse square is the centre of the town.
- East Central College — the community college campus on the edge of town.
- Highway 50 — the main route through Union and the way most of our journeys here finish.
- Highway 47 — the north-south road linking Union toward Washington and the river.
- The surrounding farmland — outbuildings, workshops and gates, which need different hardware from a front door.
What Union Jobs Usually Involve
Out here the properties are further apart and often have more doors than a suburban house — a back door, a workshop, a barn, a gate. Hardware on outbuildings tends to be older and more exposed to weather than anything on the house, so it wears differently and is worth looking at while we are on site.
We cover all of Franklin County, and Union shares a run with the towns around it: Washington, Gray Summit, Pacific and Eureka. If you have neighbours or family in any of those needing work too, say so — it is easier to plan one trip than three. See all service areas.
We are mobile, so there is no Union 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.
Union Locksmith Questions
How long will it take you to reach Union?
It varies, and we would rather say so than invent a number. Union is at the far end of our coverage, so timing depends on distance, I-44 traffic, weather, and the calls already booked. Call (636) 628-7803 and we will give you a current estimate before anyone sets off.
Is it worth calling you out for one small job?
It is, but given the distance it is worth doing everything in one visit — the sticking door, the outbuilding with no key, the spare that never worked. Tell us the full list when you call so we arrive with the right parts.
Can you set up a master key system for my business?
Yes. A master key system gives you one key that opens everything while staff hold keys that open only what they need. It has to be planned around who should reach what, so it starts with a conversation rather than an order for hardware.
Do you work on barns, workshops and gates?
Yes. Outbuilding hardware is usually older and far more weather-exposed than anything on the house, so it wears differently. Mention what you have when you call and we will bring suitable hardware rather than domestic locks that will not last outside.
Do you cover the rest of Franklin County?
Yes — Washington, Pacific and the surrounding area are all in our coverage. Call with the exact address and we will confirm availability for that day.
