Commercial Rekeying
The renovation is finished and the contractors have gone, along with the loaner keys they used for six weeks.
In plain words
For most business doors, rekeying is the sensible middle path between doing nothing and buying new hardware. Commercial cylinders are built to be repinned many times, and a lever set, mortise lock or storefront cylinder in decent condition has years left in it. Rekeying keeps the finish, the door preparation and the handles you already have and changes only the small brass pins inside. Where a cylinder is worn, corroded by winter salt or too light for the room behind it, the locksmith says so and offers a replacement for that door alone; the rest are rekeyed to the new plan.
How the visit goesYou have just signed the lease on a unit the previous tenant ran for a decade. The landlord handed over three keys, the back door wears a padlock nobody can open, and nobody can say how many front-door keys are still out there.

How the visit goes
Choosing the window and the order of doors
The last part of the assessment is practical: when can the work happen, and in what order. A retail shop may prefer the hour after closing; a restaurant, the mid-morning lull; a warehouse, the gap between the last outbound truck and the night shift. The locksmith also asks about deliveries, the cleaning crew, the alarm monitoring company and anyone else who holds a key and needs a new one before their next visit. From this comes a sequence, typically the doors staff use least first and the main entrance last, so there is always a working, lockable way in and out while the cylinders are being changed.
Storefront and mortise cylinders
Aluminum storefront doors carry a threaded mortise cylinder held by a small set screw in the door edge. The locksmith loosens the screw, spins the cylinder out, repins it, and threads it back to the same depth so the cam engages the deadbolt or hook bolt behind it and nothing else. Mortise locks in older office doors work on the same principle with a heavier lock body. On both, the depth and cam type matter as much as the pinning: a cylinder a turn too far in or a cam of the wrong shape will feel right in the hand but fail to throw the bolt, so each is cycled open and closed.
Keys counted into named hands
Alongside the chart comes a key register: each key's stamped code, the person it was issued to, the date, and a line for the date it comes back. Filling it in as keys are handed out on the first morning takes ten minutes and pays off at every departure afterwards, because the question becomes 'return key A-07' rather than 'did she have a key?'. Spare keys are counted too and kept somewhere locked rather than in the drawer where the old tangle lived. When the register and the chart agree with the keys on the hook, the business knows exactly who can open it, which is the whole point of the exercise.

What affects the quote
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.
Doors 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.
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.
What to have ready
- Are any cylinders stiff, loose or hard to turn at the moment?
- Can you gather every existing key so they can be read on site?
- How many doors, padlocks and cabinets do you want included, and where are they?
Commercial Rekeying: questions
QuestionsWe are a landlord with a tenant leaving. When should the unit be rekeyed?
Between tenants is the ideal moment: the departing tenant has handed back their keys, the new one has not yet received any, and the unit is empty for the work. The incoming tenant then starts on keys nobody else has held, and the landlord's own master or emergency key is set up at the same time. Where a lease has ended in dispute, the locksmith asks to see the paperwork before changing locks on a unit that still holds a tenant's goods.
Should we rekey every time an employee leaves?
Rekey when a key has not come back or when the departure was unfriendly; when a key is returned and the register confirms it, the cylinders it opened are as secure as before. Businesses that want a response to every departure without a visit each time fit interchangeable cores and swap them in-house. Whatever the trigger, dealing with only the cylinders that key opened keeps the response proportionate.
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.
