Why Upgrade Your Commercial Security?
Employee Turnover
When staff members leave, you don't know if they made copies of their keys. Rekeying your business is a cost-effective way to ensure former employees no longer have access.
Access Control
Not every employee needs access to the server room or the manager's office. A Master Key System allows you to designate zones of access, improving internal security.

How a Master Key System Actually Works
Most business owners have heard the term and few have had it explained. It is worth understanding before you commission one, because the design decisions are difficult to reverse.
A master key system is a hierarchy. At the bottom, each person holds a change key that opens only their own door. Above that, a master key opens a defined group — one floor, one department, one building. At the top, a grand master opens everything. Every cylinder is pinned so that more than one combination lifts it to the shear line, which is what allows two different keys to turn the same lock.
The practical value is that a supervisor carries one key instead of fourteen, and a new hire gets access to exactly what they need and nothing else. The practical cost is that the system has to be planned before the first cylinder is pinned. Adding a floor to a system that was never designed to expand usually means repinning the whole thing.
One trade-off deserves saying plainly: every level of masking you add slightly reduces the pick resistance of the individual cylinder, because there are more shear points. For most offices this is irrelevant. For a pharmacy, a cash room, or a server closet, we would usually recommend keeping that door off the master entirely and issuing a separate key.
"Do Not Duplicate" Does Not Work
If your keys are stamped Do Not Duplicate and you have been treating that as security, it is worth knowing what it actually is. The stamp carries no legal weight and no hardware store is obliged to refuse. Any employee can walk into any of a hundred shops in South Florida and walk out with a copy, and you will never know it happened. What does work is a restricted keyway — a patented blank that is not sold on the open market and can only be cut by an authorised dealer against a signature on file. Medeco and Mul-T-Lock both operate this way, and we are an authorised dealer for both. The difference in practice is that duplication becomes a paper trail instead of a five-dollar transaction, and you know exactly how many keys exist because you authorised each one.
When an Employee Leaves With Keys
This is the most common commercial call we take, and the response depends on how the departure went.
Routine departure
Keys returned, no bad blood, no reason for concern. Rekey the exterior doors and any space they had sole access to, at your convenience. The point is not distrust — it is that you cannot know whether a copy was made two years ago and forgotten in a drawer.
Termination or dispute
Rekey the same day, before the person has left the parking lot if you can manage it. Exterior doors first, then anything holding cash, records, or inventory. If you are on an access control system, disabling the credential takes seconds — but check whether they also held a mechanical key for the override, because most buildings have one and it is usually forgotten.
If you find yourself doing this several times a year, that is the signal to move to a restricted keyway or credential-based access. At a certain rate of turnover, rekeying repeatedly costs more than converting once.
Exit Devices and the Doors You Are Not Allowed to Lock
Panic bars are not a security product. They are a life-safety product, and the rules around them are not negotiable. In any occupancy that requires one, the door must open from the inside with a single motion, without a key, without a code, and without any special knowledge — every time, whether or not the power is on. Chaining a rear exit after hours, adding a thumb-turn deadbolt above a push bar, or wiring a maglock that fails locked are all straightforward ways to fail an inspection and, far worse, to trap people. Where a business genuinely needs to stop an exit being used as a casual entrance, the correct answer is an alarmed exit device or a delayed-egress unit installed to code — not a padlock. If an inspector has flagged a door and you are not sure what is being asked of you, send us a photo. It is usually a quick conversation.
Mechanical Keys or Access Control?
Both are good answers to different problems. The wrong one is expensive, so it is worth being blunt about the trade-offs.
Mechanical keys suit you if
You have a stable team, a handful of doors, and no need to know who opened what and when. Nothing to power, nothing to update, nothing that stops working in an outage — and in a region that loses power to storms every year, that is worth more than it sounds. Lower cost to install and effectively no running cost.
Access control suits you if
Staff turn over regularly, different people need different hours, or you need an audit trail for insurance or compliance. Removing someone takes seconds instead of a rekey. The costs to plan for are the ongoing ones — software, credentials, and battery or wiring maintenance — plus deciding in advance how every door behaves when the power fails.
Plenty of businesses end up with both: credentials on the main entrance and the doors that matter, good mechanical hardware everywhere else. There is no prize for putting a card reader on a supply closet.
