Commercial Rekeying
The drawer behind the counter holds a tangle of keys with tape labels: front old, side, Dave.
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 break-in overnight took the cash float and a staff member's bag with her work keys inside it. The glass is being replaced this morning, but the key that opened the door yesterday will still open it tonight unless the cylinders are changed.

How the visit goes
Which doors are the landlord's
In a plaza, an office building or a multi-tenant industrial unit, some doors on your floor plan are not yours to rekey. Corridor doors, electrical and mechanical rooms, shared loading doors and the building's fire exits usually sit on the landlord's master system, and a suite entrance may be required to accept the landlord's key as well as yours. The locksmith sorts the openings into two columns before starting: those the lease puts under your control, which get the new plan, and those that stay as they are or need the property manager's say-so. Where a suite door must accept both a tenant key and the building master, it is pinned to do exactly that.
Repinning a standard cylinder
The cylinder is taken off the door and its plug is slid out with a follower, a small tube that holds the top pins and springs in place so nothing scatters. The old bottom pins are tipped out, and a new combination is chosen from the pinning records so it does not collide with any other key in the plan. Fresh pins of the matching depths are dropped into each chamber, the plug goes back in, and the new key is tried: it should turn as smoothly as if the lock were new, and the old key should stop dead. The cylinder is then refitted and adjusted so the cam or tailpiece throws the bolt fully.
A keying chart in plain language
You leave the visit with a one-page chart that lists every opening by name, the key group it belongs to, the code stamped on that group's keys and how many were cut. It is written for the manager, not the locksmith: the stockroom is called the stockroom, and a glance shows that key group B opens the office and the cash room and nothing else. The bitting details that a locksmith needs to add a cylinder later are kept separately and securely. Pin the chart inside the manager's cupboard, keep a copy off site, and it becomes the reference every future key question is answered from.

What affects the quote
Cylinders 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.
Mix of lock types
A key-in-lever cylinder, a storefront mortise cylinder, a back-door rim cylinder and a padlock take different handling, though several full-size formats can share one pin kit for the same key system; a premises with a wide mix of cylinder types and brands still takes longer than one with one.
A master key plan
Pinning cylinders to accept both a change key and a master, and designing the chart so no key opens a door it should not, is more work per cylinder than keying everything alike.
What to have ready
- How many doors, padlocks and cabinets do you want included, and where are they?
- When is the premises quiet or empty enough for the work?
- Are any cylinders stiff, loose or hard to turn at the moment?
Commercial Rekeying: questions
QuestionsWill rekeying affect our alarm system or card readers?
Mechanical rekeying leaves electronics alone: alarm panels, card readers and keypads keep their codes and credentials. What changes is the list of people holding keys, and it is worth updating the alarm company's keyholder list and retiring the codes of anyone who has left at the same time, since keys and codes usually walk out together. Where a door has both a card reader and a keyed override, the override cylinder is rekeyed with the rest.
What is the difference between rekeying a business and replacing its locks?
Rekeying keeps every lock on the door and changes only the pins inside the cylinder, so a new key works and the old ones stop. Replacing swaps the hardware itself. Commercial cylinders are made to be repinned many times, so rekeying suits any lock in sound condition and leaves the levers, trim and door untouched. Replacement is chosen door by door for cylinders that are worn, corroded or too light for what they protect.
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.
