Commercial Rekeying
Two people left over the summer and the keys they handed back came up one short. Nobody is sure whether the missing key was for the front door, the stockroom or both, and the sign-out sheet stopped being filled in a year ago.

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 goesThe renovation is finished and the contractors have gone, along with the loaner keys they used for six weeks. Trades, delivery drivers and an inspector all came through, and the front door still answers to the key that was passed around the site.

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.

Retiring the old keys
The job is finished when the old keys are proven dead, not when the new ones work. At every rekeyed opening the locksmith tries a sample of the old keys, including the master if one existed, and confirms that each one enters the keyway and turns nothing. The collected old keys are then cut through with snips in front of the manager and can be handed back as scrap or taken away. Any door deliberately left on its original key is written on the chart in plain words so nobody assumes it changed. That last check is what turns a day of brass work into a genuine reset of who can open the business.

How copies get made from now on
If the business moved to a restricted keyway, the way keys are copied has changed for good. Hardware stores and kiosks do not stock the blanks, which makes running off a spare on a lunch break far harder to arrange. New keys are ordered from the locksmith by one of the people named on the authorization letter, who signs for them, and the register grows by exactly that many. On a standard keyway, the same discipline is kept by habit: the manager orders keys, the register records them and a key that turns up unlisted prompts a question. Either way the count on paper and the count in the world stay the same, which is what key control means.

What affects the quote
- 1
Several locations
Rekeying two or three sites onto one keying plan means travel between them and a chart that spans buildings, quoted per site plus the shared design work.
- 2
Distance to the premises
Travel to the site is part of the call-out, and a unit in a downtown plaza and one at the end of a rural industrial road are different trips.

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.

Commercial Rekeying: questions
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.
Do I need my landlord's consent before rekeying my unit?
Read the lease, because that is where the answer lives. Commercial tenancies are governed mostly by the lease itself, and many leases require the tenant to tell the landlord when locks change, to provide a key for emergencies, or to use the landlord's approved locksmith. Doors on the building's master system, such as corridor or service doors, are normally the landlord's to change. Bring the lease to the assessment and the locksmith will sort the doors accordingly.
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.

What the census means at the door
19%
Newer homes. About 19% of homes in Markham were built in 1980 or earlier, according to the 2021 Census.
Recent builds often have steel or fibreglass entry doors rather than solid wood. They resist warping and take hardware well, and a locksmith fitting a deadbolt or reinforced strike works with the door's construction so screws bite into something solid.
56%
A mix of homes. Single-detached houses make up about 56% of homes in Markham (2021 Census).
Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
