A business door rarely fails the same way a house door does, because it opens far more often and often has to satisfy a fire or egress rule a home door never faces. Replacement starts by identifying what the opening actually is: a mortise-prepped steel door, a narrow-stile aluminum storefront, a fire-rated door that needs listed hardware, or an exit serving enough people that code calls for panic-style release. The locksmith fits hardware built for that specific opening, connects it correctly to any electric strike or access-control wiring already present, and hands over keys cut and logged to the business's own system.
How the visit goesAn inspection report flagged the rear exit as needing hardware that opens with one motion and no key, and that door currently has an ordinary keyed knob on the inside.

How the visit goes

- 1
Confirming who can authorize the work
Before any hardware is opened up, the locksmith confirms who is speaking for the business: an owner, a property manager, or a staff member the account recognizes as authorized to order and pay for the work. On a multi-tenant building this also means confirming which doors belong to which lease. This step exists for the same reason a home lockout starts with identification: a business's security is only as good as its record of who was allowed to change it, and a clear authorization at the start keeps that record clean.

Connecting any electrified or access-control hardware
Where the opening already carries an electric strike, a maglock, a door position switch or a card-reader tie-in, that wiring is reconnected to the new mechanical hardware and tested together rather than assumed to still line up. Voltage, fail-safe or fail-secure operation, and monitoring contacts are confirmed against what the access-control or alarm system expects, since electrified hardware that is almost, but not quite, matched to the mechanical lock is a common source of a door that buzzes open but still needs force.

A storefront that closes the way it should
For a narrow-stile or glass storefront door, the finished job means the hookbolt or deadlatch engages fully across its travel every time, without the shoulder-check that a worn or mismatched lock used to need. Staff closing up for the night can throw the lock once and trust it caught, and the business is no longer relying on a habit of double-checking a door that should simply work. The hardware's finish is also suited to public-facing use, holding its appearance under daily handling.

What affects the quote
- 1
Interchangeable-core hardware
Interchangeable-core cylinders cost more up front than standard ones but reduce the cost of every future rekey, since the business can swap cores itself. Whether that trade-off suits you shapes which cylinder type is quoted.
- 2
Grade and duty rating of the lock
Hardware built for higher cycle counts and rougher daily handling costs more than a lighter-duty equivalent, and the right grade for a busy delivery door is not the same as for a quiet interior office.
- 3
Site access and building type
A ground-floor storefront is the simplest case to reach and work on. A unit inside a larger building with its own access rules, or a site requiring coordination with building management, can add steps the quote takes into account.

Commercial-Grade Lock Replacement: questions
Can a tenant request commercial lock replacement, or does it have to go through the landlord?
This depends on the lease and on which doors are involved. A tenant can generally arrange work on hardware inside their own leased space, while entry doors, shared corridors and building-wide systems usually involve the property manager or landlord, since a change there can affect other tenants' access as well. Confirming this before the visit avoids hardware being installed that has to be redone.
Will replacing the lock affect my alarm or access-control system?
It can, if the door already carries a door position switch, an electric strike or a card reader, so the locksmith checks for that wiring before starting and reconnects and tests it alongside the new mechanical hardware. The goal is a door where the mechanical lock and the electronic system agree with each other rather than one working around the other.
Do you replace hardware after an attempted break-in even if the door still locks?
Yes, and it is worth having it checked even when the door still appears to function. A cylinder that was drilled at, pried or struck can be weakened internally without showing it externally, and a bent strike or a cracked frame around the lock can let a door appear locked while offering far less resistance than it should.

What the census means at the door
58%
Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.
Basement and side entries on older homes were often fitted long after the house was built, with whatever lock was on hand. Bringing those doors up to the standard of the front entry, and onto the same key, is a common and satisfying job.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Landlords and property managers dominate in attached housing, and they want keys organised. A locksmith sets up master systems so a manager carries one key while each tenant's key opens only their own door.
