Commercial Rekeying
The office has been reshuffled twice since the locks were last touched.
In plain words
Commercial rekeying changes the pins inside a business's existing lock cylinders so that a new key operates them and every earlier key stops working, while the hardware itself stays on the door. The locksmith works from a list of the openings the business controls and the people who need to pass through each one, sets the cylinders to fresh combinations, cuts keys to match and records which key opens which door. Because nothing is replaced unless it is worn, a whole premises can be brought back under control in one scheduled visit, with the doors locking and unlocking exactly as before but answering only to keys you have counted.
How the visit goesThe manager's key ring went missing somewhere between the bank and the car, and the master on it opened every door in the building. Until the cylinders are changed, whoever finds it is holding the run of the place.

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.
Exits that still open the way they must
Rekeying changes who can come in; it never changes how people get out. Every exit door and every door on the way to one is left opening from the inside with a single motion and no key. On a door with a panic bar, the outside cylinder simply controls entry, and the bar keeps working exactly as before. Once the locksmith has finished, walk the exit routes yourself, push each bar and turn each thumb-turn, and make that walk a habit at the start of every season so a new deadbolt or a helpful padlock never creeps onto an exit.

What affects the quote
Upgrades chosen on the day
Some businesses use the visit to move to interchangeable cores, add a lockbox for the alarm company or fit a heavier cylinder on the cash room. Each is a separate line you can accept or leave.
Documentation 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.
Interchangeable cores versus repinning
Cores swapped with a control key are the shortest work on site, while cylinders that must come apart on a bench take longer. Supplying spare cores for the manager to hold is priced as its own line.
What to have ready
- Do you want one key for everything, or separate groups with a master?
- How many keys do you need cut, and for whom?
- When is the premises quiet or empty enough for the work?
Commercial Rekeying: questions
QuestionsWhat is an interchangeable core and why is it suggested for staff turnover?
A small-format interchangeable core is a small figure-eight cylinder that slides out of the lever, deadbolt or padlock when a control key is turned, with no tools needed; larger doors sometimes use a large-format core with a different profile instead. A manager keeps the control key in the safe and a few spare cores on hand, so a missing key means the core is swapped in moments and repinned later. For a business with frequent staff turnover, it turns a call-out into a routine.
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.
Is a restricted keyway worth it for a business?
A restricted keyway uses blanks that only the locksmith or authorized source can obtain, released against whatever that key-control program requires, a signed letter, card, signature record or factory authorization naming who may order keys. Hardware stores and kiosks have no blanks, so copies are far harder to get without your say-so. It costs more per key than a standard keyway and is most valuable where keys pass through many hands, such as retail with part-time staff, shared premises or anywhere the count of copies has drifted before.
