Keys to your building, under your control.
Storefronts on John Sims Parkway. Offices off Government Avenue. Churches, dental suites, and the rental portfolios that somebody has to manage. Commercial work is not residential work with a bigger door on it — it is a key system, a life-safety code, and a schedule that cannot be interrupted. We handle all three.
Master key systems · Same-day turnover rekeys · Panic hardware · Scheduled after-hours work

The businesses we actually work on here
Small town, specific commercial stock: aluminum-and-glass storefronts, converted houses, modest slab buildings. Each has a signature failure.
The John Sims corridor
State Road 20 is the commercial spine, and most of what fronts it is glass in an aluminum frame. Adams Rite style latches, mortise cylinders, door closers — a completely different parts list from a house.
John Sims Parkway →Churches
The hardest key problem in town: dozens of volunteers, decades of turnover, and nobody left who remembers who was given what. The fix is almost always a small, clean master system replacing thirty years of improvisation.
Medical & dental suites
A records room, a supply cabinet, and a front door — three different levels of who-gets-in. Those levels belong in the key system, not in a drawer of unmarked keys.
Landlords & property managers
You need into every unit; each tenant needs into exactly one. That is textbook master keying, and it is the most common reason a property manager calls us.
Rekey between tenants →Master key systems, explained honestly
Everybody wants "one key that opens everything." It is a real thing, it is worth having, and there is a tradeoff nobody tells you about. Here is the whole picture.
A master key system is a hierarchy. At the bottom, each door has its own change key — the one you hand the tenant, the volunteer, the front-desk person. It opens their door and nothing else. Above it sits the master key, which opens every lock in the group. Bigger buildings can add a middle layer: a wing or department key that opens its own wing but not the building.
How the cylinder actually does it
A plain pin-tumbler cylinder has one stack per chamber: a bottom pin and a top driver. When the right key lifts each stack so the split between them lands exactly at the shear line, the plug turns. One correct height per chamber, one working key.
Master keying adds a third pin to some chambers — a thin master wafer between the bottom pin and the driver. Now that chamber has two heights that put a split at the shear line: one for the change key, one for the master. Repeat across a few chambers and the cylinder opens for two different keys, on purpose.
The tradeoff, said out loud
Every wafer is an extra split in that chamber, and extra splits are exactly what a picker hunts for. So masterkeying, by its nature, slightly reduces pick resistance. It also creates key interchange: with multiple valid heights per chamber, the math produces unintended combinations that open locks they were never meant to. In a small, deliberately designed system that is negligible. In a system that grew by accident — a wafer added here, a lock "adapted" there, three generations of keys still circulating — interchange becomes real and the building's security quietly turns into fiction.
Which is the point: a small, well-designed system beats a big improvised one, every time. Before we cut a key we build a door schedule — every door, who must open it, who must not — and design the shallowest hierarchy that satisfies it. Fewer levels, fewer wafers, fewer keys in the wild. Then we keep the pinning chart, so the next change is a re-pin and not an archaeological dig.
The day somebody leaves with a key
This is the most common commercial call we get, and the one people put off. An employee quits, gets let go, or drifts away. Their key does not quit with them. Maybe they hand it back. Maybe they hand back a key. There is no way to know whether a copy was cut at a hardware counter three years ago, and "Do Not Duplicate" stamped on a blank is a request, not a lock.
Once a key is outside your control it is not a key any more, it is an open liability in someone's junk drawer. Insurance adjusters and lawyers both care whether a break-in shows forced entry. A clean, unforced entry after a termination is a bad conversation to be in.
So: rekey same day. Rekeying re-pins the cylinders you already own — the old key stops working, a new one starts. Same hardware, same doors, new keys. On a master-keyed building we re-pin to a new change key, and if the departing person held a master we reset that level too. Which is exactly why keeping the system small pays for itself the first time this happens.
What we bring to a turnover call
- Pinning kit and a follower — cylinders come apart on your counter, not in a shop across the bridge
- Key machine in the truck, so new keys are cut and stamped before we leave
- A written key record: who holds which key, and how many exist
- Mortise and rim cylinders on hand for the storefront doors that need them
Panic hardware and the door that has to open
The most important lock in your building is the one that is not allowed to lock.
An exit device — the horizontal push bar on a marked exit — exists so anyone can get out with one motion, in the dark, in smoke, while being shoved from behind. That is what free egress means: the person leaving needs no key, no code, no knowledge of the door at all. One push and the latch retracts.
People get this backwards. The worry is always about somebody getting in. The far larger problem is a door people cannot get out of. A locked entrance costs you inventory. A blocked exit costs you something you cannot replace, which is why fire code takes egress so seriously.
Concretely, for a storefront or a church fellowship hall:
- Never chain, padlock or deadbolt a marked exit while people are inside. Not "just for the slow hour." Not "just for the delivery." Never.
- If people are coming in the back door, solve it on the outside — an exit device with no outside trim, or with keyed outside trim. The bar still opens from within.
- If merchandise is going out that door, the answer is a door alarm or a code-compliant delayed-egress device, not a chain.
- A bar that needs a shoulder, a sticking latch, a device dogged down permanently — those are not cosmetic complaints. They are what fails on the worst day.
We service, adjust and replace exit devices, and we will say plainly when a request would put a code violation on your building. That is the one part of this job where the answer is not negotiable.
The rest of the hardware list
Commercial doors are assemblies. The lock is one part, and usually not the part that is actually broken.
Door closers
A closer that slams has its latch speed wrong. A closer that leaves the door standing open two inches is a building that is not locked at night. Both are an adjustment before they are a replacement, and we check the adjustment first.
Storefront latches
Aluminum-and-glass doors use narrow-stile hardware: an Adams Rite style deadlatch driven by a mortise cylinder. When the key turns but the door will not open, it is usually the tailpiece or the cam, not the cylinder. Diagnosing that correctly is the difference between a small fix and a whole new lock.
Cabinets, desks, mailboxes
The small locks everybody forgets. File cabinets whose key was lost two managers ago, desk drawers, mailbox compartments. Picked, impressioned, or replaced with a matched core — no drilling if we can avoid it.
Access control, honestly
Keypads and fobs are excellent for turnover: delete a credential instead of re-pinning a building, and get an audit trail of who opened what and when. But a reader is only as good as the door and frame it is bolted to. A fob on a weak frame with a short latch throw is theater. We fix the door first, then the electronics.
We work around your business day
Nobody wants a locksmith with a door off its hinges at eleven in the morning while customers are trying to walk in. Most commercial work here — a rekey, a master system rollout, a closer replacement — gets scheduled after close or before open, to a fixed window, so you know when your doors are back in service. If your traffic is the lunch hour on John Sims, we come at seven. If you are a church, we come Tuesday.
Locked out of your own storefront right now? That is a different call — see emergency lockout, and phone rather than filling in a form. If the building is anywhere in our service area, you get an honest arrival window instead of a hopeful one.
Commercial questions we get
An employee just quit. How fast can you rekey?
Same day, in most cases. Rekeying re-pins the cylinders you already have, so we do not need to source new hardware — we bring the pinning kit and the key machine to your door and hand you new keys before we leave. If the person held a master key we reset that level as well. Do not wait on this one. A key you cannot account for is not a key, it is an open door with a delay on it.
Does master keying make my locks less secure?
Slightly, and we would rather say so than pretend otherwise. Each master wafer adds an extra split in that pin chamber, which is what a picker looks for, and multiple valid heights per chamber create unintended key combinations — key interchange. In a small, deliberately designed system the effect is negligible and hugely outweighed by actually knowing who can open what. In a sprawling improvised system it is a genuine problem. Design the system shallow, keep the chart, and you get the convenience without the rot.
Can I lock the back exit during the day to stop people wandering in?
Not with a chain, padlock or deadbolt, and not while anyone is in the building. Fire code requires free egress: a marked exit must open from the inside with one motion, no key and no knowledge. The correct fix is on the outside of that door — an exit device with no outside trim, or keyed outside trim — so nobody enters but everybody can still leave. If the concern is theft, a door alarm or a code-compliant delayed-egress device is the answer, never a chain.
Should I switch to keypads and fobs instead of keys?
It depends on your turnover. If people come and go often, electronic credentials are worth it — you delete a fob in seconds instead of re-pinning a building, and you get a log of who opened which door and when. But access control does not upgrade the door itself. If the frame is weak, the strike is shallow, or the latch throw is short, a reader just puts a computer on a door that still gives way to a shoulder. We look at the door and frame first and tell you which one is actually your weak point.
My key turns but the storefront door still won't open. What is that?
On an aluminum-and-glass door, usually not the cylinder. Narrow-stile doors use an Adams Rite style deadlatch driven by a mortise cylinder through a tailpiece and cam. When the tailpiece is worn, misaligned, or the wrong length, the key turns freely and moves nothing. It also happens when the door has sagged and the latch no longer lines up with the strike. Both are fixable without replacing the whole lock, if it is diagnosed properly.
Can you do the work after hours so we don't lose a business day?
Yes, and for most commercial jobs that is what we recommend. Rekeys, master system rollouts, closer replacements and hardware swaps all get scheduled before open or after close, in a fixed window, so your doors are back in service when your customers arrive. Tell us your hours when you call and we will build the visit around them.
