Commercial Rekeying
The drawer behind the counter holds a tangle of keys with tape labels: front old, side, Dave. Some open things, some open nothing, and the hardware-store copies mean the true count drifted long ago past anything written down.
Commercial Rekeying
In plain words
Rekeying is also a chance to decide how the keys should work, not simply to change them. Most businesses settle on a small number of key groups: one key for the doors every employee uses, another for the office, cash room or server closet that only managers open, and perhaps a single master for the owner that opens everything. The locksmith maps this out on a keying chart before touching a cylinder, then pins each lock so the plan holds true on the door. Staff carry one key instead of a ring, managers carry two, and the chart tells you at a glance who can open what.
How the visit goesA key turned up in the parking lot with the shop's name on its fob. It came back to you, which is lucky, but it means keys are leaving the building on rings you have never seen, and the shop's locks have not changed since opening day.

How the visit goes
A walk of every door and lock
The locksmith walks the premises with you and lists every opening that should be in the plan: the customer entrance, the receiving door, offices, stockroom, cash room, server closet, the mailbox, cabinets, and any padlocks on gates, compounds or roll shutters. Each lock is identified by type, since a mortise cylinder in an aluminum storefront door, a key-in-lever set on an office, a rim cylinder on a back door and an interchangeable core in a stockroom each come out and go back in differently. The keyway and the maker's mark are noted, and the condition of each cylinder is checked, so the list from the walk is what the quote and the work are built on.
Padlocks, cabinets and the mailbox
A business is more than its doors, and the same visit brings the smaller locks into the plan. Rekeyable padlocks on the compound gate, the propane cage or the roll shutter can be pinned to the same key as the back door, so the opening crew carries one key instead of four. Filing cabinets, the till drawer, a medicine or chemical cupboard and the display cases can be keyed alike for the staff who use them or kept separate for the manager. The lobby mailbox, which often still answers to a key from two tenants ago, gets a fresh cylinder or is repinned where its design allows. Each small lock is added to the chart alongside the doors.
Storefront hardware ready for the salt
Cylinders on a street-facing door live a hard life: slush, salt spray from the sidewalk plough and a dozen freeze-thaw swings a winter. Each cylinder handled during the rekey is cleaned and dressed with the lubricant approved for that model, a dry graphite, PTFE or specified liquid lubricant applied sparingly, since too much graphite can gum a cylinder just as oil traps grit. Keep it that way with a puff of the same lubricant each autumn and a wipe of the key before it goes in on a slushy morning. A set screw snugged, a cam aligned and a bolt that throws fully are part of the handover, so the rekeyed door also locks more cleanly than it did before.

What affects the quote
Same fees day, night or weekend
1Cylinders that need replacing
Where a worn, corroded or low-grade cylinder is better replaced than repinned, the new part is added for that door alone, and the locksmith points it out before the work begins.
2Documentation and register
A keying chart, a key register and stamped codes on every key are part of a proper commercial rekey, and the quote names the paperwork so it is never skipped.
3Doors out of alignment
A door whose cam, strike or closer needs adjusting so the freshly rekeyed cylinder throws the bolt fully is corrected during the visit, and that adjustment is a separate item.
Commercial Rekeying: questions
What is a master key system and does a small business need one?
In a master key system each lock accepts its own change key and also a master key above it, so a manager carries one key while staff carry keys that open only their own doors. Small businesses with three or four doors often manage without one. A master earns its place once there are several rooms with different people in them, or several locations, and the owner would otherwise carry a ring of keys.
How long should we set aside for a commercial rekey?
It depends on the count and the mix. A shop with a front door, a back door and a stockroom is a short visit; an office suite with a dozen lever sets, a master key plan and a mailbox takes a good part of a day. Interchangeable cores are the shortest of all, since they are swapped rather than repinned on site. The locksmith gives a time estimate at the assessment, once every cylinder has been counted.
What information should I have ready before the locksmith arrives?
A list of the doors and other locks you want included, a copy of the lease or the property manager's contact, every existing key you can find, and a rough idea of who needs to open what. Note which doors, if any, are interchangeable cores and where the control key is. Knowing your quiet hours and who opens up in the morning helps the locksmith plan the order of work and the key handover.
