Peachtree Corners, Georgia
Business premises have a problem homes do not: the list of people who need to get in changes constantly, and different people need to reach different rooms. That is a system design question before it is a hardware question, and it is most of what we do here.
The underlying problem
Most business access arrangements were never designed. They grew. A key was cut for someone who needed the back door, another for the person covering weekends, a third because the first one went missing. Five years later nobody can say with confidence which keys exist or what they open.
A master key system replaces that with a structure. It is worked out on paper first: which doors exist, which groups of people need which of them, and who needs to reach everything. Then the cylinders are pinned to match. One master key opens the whole site, while individual keys open only the doors their holder should reach.
The payoff shows up when something changes. A designed system lets you rekey one branch of the structure when a person leaves, instead of re-cutting every key in the building and hoping you found them all.

Commercial services
Designed and pinned around your actual layout and staffing, so one key opens everything and each individual key opens only what it should.
Cylinders re-pinned when a lease changes, a suite turns over, or someone with keys leaves. Faster and cheaper than replacing hardware.
Card and code-based entry where the people change too often for metal keys to keep up. Credentials are granted and revoked without touching the cylinder.
Mortise cylinders, latches and pulls for aluminium storefront doors, which behave nothing like a residential door and need hardware built for the volume of use.
Push bars and exit devices supplied, fitted and adjusted so they release cleanly from the inside every time.
Getting a premises open when the door will not cooperate, after we have confirmed you are entitled to have it opened.
Choosing an approach
Neither is universally correct. The right answer depends mostly on how often the list of people changes.
Best where access is stable and the doors are conventional. No power, no network, nothing to fail in an outage.
Best where people come and go frequently, or where you need to know who opened a door and when.
The most common real-world answer. Credentials on the doors that change often, keys on the ones that do not.

The details that matter depend on whether this is a vehicle, a home or a business.
Never share alarm codes, PINs, access-control credentials or passwords — a locksmith does not need them to quote your job.

Your service request
Start at step 1 — we'll assemble your request as you go.
Locksmith Lawrenceville Pro takes service requests by phone so a real person can qualify the job before anyone is dispatched. Nothing on this page is submitted anywhere — it just gets your details in order before you call.
Questions
Each cylinder is pinned to accept more than one key combination: the individual key for that door and a master key that operates every door in the system. The structure is designed around your layout and staffing before anything is pinned.
Rekey the cylinders that key operated. Within a properly designed master key system that is normally one branch of the structure rather than the entire building.
If your list of people changes often, or you need to know who opened a door and when, credentials are usually the better fit. Where access is stable, a mechanical system is cheaper and has nothing to fail during a power cut.
Yes. We are available 24 hours a day and most substantial commercial work is better done when the premises are empty. Say so when booking and we will schedule it that way.
Yes. Storefront doors use mortise cylinders and hardware built for far heavier use than residential locks, and fitting residential hardware to them is a false economy.
Someone who can show they are entitled to change access to the premises — an owner, director or named manager, with documentation that matches. For leased premises the landlord's consent is sometimes required as well.
