Commercial Rekeying

You 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.

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.

The call
The 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.

  1. Scene 1

    The state of the cylinders and the doors

    A cylinder about to be repinned is examined the way a mechanic looks over a part before rebuilding it. The plug should turn smoothly with the right key, the pins should spring back cleanly, and the face should be free of the green bloom that salt spray leaves on storefront hardware after a few winters. The locksmith also checks how the door closes: a strike that no longer lines up, a closer that slams, or a deadlatch that fails to catch will keep a freshly rekeyed door from locking properly. Most cylinders pass and are repinned; a worn or corroded one is pointed out so you can choose a replacement for that opening.

  2. Scene 2

    Door by door, never a gap

    The sequence agreed at the assessment is followed on the day. The locksmith finishes one opening entirely before beginning the next: cylinder out, repinned, refitted, tested with both the new key and the old, and locked again. Only then does the next door come apart. The main entrance is usually left for last and done while someone from the business is present, so there is never a moment when the premises has a door that will not lock. Staff who are working during the visit are handed their new key before the door they use is changed, and a short note goes to anyone off shift about where to collect theirs.

  3. Scene 3

    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 shapes the quoteBuchanan Lock Services

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.
No existing chart or keys
When nobody knows what the current keys open, the locksmith reads and records each cylinder before planning the new keying, and that reconstruction is time in the quote.
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.

What to expect, answered

We 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.

What 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.

How often should a business change its keys as a matter of routine?

There is no fixed interval. Rekey on events rather than on a calendar: a key not returned, a lease change, a break-in, a renovation crew finished, or a key count that no longer matches the register. Businesses with a good register and a restricted keyway often go years between rekeys because nothing prompts one. A yearly check of the register against the keys on the hook is the habit that tells you when the time has come.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 61 in 100 homes · older homes
  • About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Decades of seasons move a frame, and an older house often has a front door that locks easily in summer and fights in winter. Setting the strike with the seasons in mind, and choosing a lubricant that stays fluid in the cold, keeps it working year round.
  • Single-detached houses make up about 56% of homes in Hamilton (2021 Census).A mix of detached and attached housing means a mix of key habits: spare keys under pots at houses, fob-and-key combinations in buildings. A locksmith can improve both, with a proper key safe or keypad here and a tidy suite cylinder there.
