Commercial-Grade Lock Replacement
The electric strike buzzes the moment the receptionist presses the release button, but the door still needs a shoulder to get past the latch, as though the two pieces were never matched.

Where a home lockout is mostly about getting one door open again, a commercial lock replacement is mostly a decision about a system: how this one door's hardware fits into every other lock the business already manages. The locksmith examines the existing keying, whether cylinders are standard, interchangeable-core or restricted, and whether other doors should be keyed the same way as this one. New hardware is chosen to match the door's fire rating and occupant load where those apply, installed without altering the door's existing prep, and finished with keys cut, tested and recorded in the business's own key-control log.
How the visit goesThe key to the office entrance turns with almost no resistance now, and some mornings the deadbolt does not fully retract until someone jiggles the handle and tries the key again.

How the visit goes
- 1
Weighing what the new hardware needs to do long term
The last part of the assessment looks past today's problem to how the business expects to manage this door going forward: does staff turnover happen often enough that an interchangeable core, which lets a key holder change the combination without pulling the whole cylinder, would pay for itself in convenience? Does the business want a restricted keyway so blanks cannot be cut at an ordinary hardware counter? These questions shape the specific hardware ordered as much as the door's physical construction does.

Selecting hardware built for this opening
With the assessment complete, the locksmith orders hardware to match: a mortise lock body for a mortise-prepped door, a heavy cylindrical lockset for a standard bored door, or a narrow-stile lock or hookbolt for an aluminum storefront. Where the door is part of a fire separation or a required exit, the hardware chosen is listed for that rating and function rather than a general-purpose substitute. Grade and finish are matched to the traffic the door takes, so a heavily used delivery door gets hardware built for that duty rather than the lightest option available.

A record the next contractor can use
The business keeps a plain account of what was fitted: the hardware model and function, the keying it was cut to, how many keys were issued and to whom, and any fire or exit rating the door carries. For a property manager or facilities team, this record answers the next question about that door without another site visit, and for a business with several locations it becomes a reference for bringing other branches onto the same standard over time.

What affects the quote
- 1
Restricted or patented keyways
A restricted keyway usually costs more as hardware than a standard cylinder, and duplicate keys are controlled through the manufacturer or distributor rather than cut freely; some restricted programs require formal registration, while others control the same blanks without a signed authorization step.

Type of hardware the door takes
A mortise lock body, a heavy cylindrical lockset and a narrow-stile lock or hookbolt are priced differently as hardware and take different amounts of labour to fit, so the quote follows what the door's own construction requires.

Removal of old hardware
Whether old locks, cylinders and strikes are left with the business, disposed of, or kept as spares for a wider system is a small choice that can affect the time and scope named in the quote.

Commercial-Grade Lock Replacement: questions
What is the difference between a mortise lock and a cylindrical lockset?
A mortise lock has its whole mechanism, latch, deadbolt and sometimes a separate handle function, built into one case that sits inside a pocket cut into the door's edge. A cylindrical lockset is a bored-in unit, simpler to service, common on standard commercial and residential doors alike. Which one your door takes depends on how it was originally prepped, not on preference alone.
Do you handle interchangeable-core (IC) cylinders?
Yes. An interchangeable-core cylinder lets an authorized key holder pull the core and swap in a new one when a key needs retiring, without removing the whole lock from the door. Businesses with regular staff turnover often move to this system because it turns a rekey into a short in-house task rather than a full service call every time.
Can you install a restricted or patented keyway?
Yes. A restricted keyway limits duplication to keys cut through the manufacturer or an authorized distributor rather than at an ordinary hardware counter, though the exact registration and proof-of-entitlement steps vary by system; a patent-protected keyway adds a further, legally backed layer of control on top of that. This is a common step for a business tightening key control after a lost key or staff turnover.

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.
