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.

In plain words

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.

Sound familiar?

The kitchen delivery door gets shouldered open more than a hundred times a shift, and lately the latch slips past the strike plate instead of catching it on the first push.

How the visit goes

  1. 1

    Finding what else is already wired to the door

    Many commercial openings carry more than a mechanical lock: an electric strike, a maglock, a door position switch feeding an alarm panel, or a card reader tied to an access-control system. The locksmith identifies everything already connected to the opening before ordering replacement hardware, since a new lock has to coexist with that wiring rather than replace it by accident. Where the connected hardware is the actual source of the problem, that gets flagged separately rather than folded silently into a mechanical lock replacement.

  2. 2

    Fitting the new lock body or lockset

    The new hardware is installed into the existing prep, with the lock body or lockset, strike and any reinforcing plate seated so the door closes without binding. On a narrow-stile storefront door, the hookbolt or deadlatch is aligned so it engages the keeper across its full travel rather than catching on one edge. On a mortise-prepped door, the case is fitted so the trim sits flush and the spindle and cylinder line up with the existing holes cut for them.

  3. 3

    Ready for the next security decision

    With current hardware and an accurate key-control record in place, the business is better positioned for whatever comes next: adding a location to the master key system, upgrading a single door to an interchangeable core so staff can rekey it without a service call, or answering an insurer's or landlord's question about what security is on a given door. None of that requires starting from scratch, because the replacement visit leaves behind hardware and documentation that a future decision can build on directly.

What affects the quote

  1. 1

    Fire-rated or listed hardware requirements

    A door that is part of a fire separation needs hardware listed for that specific rating, which is a narrower and typically costlier category than general-purpose commercial hardware, and the quote reflects that requirement rather than a standard substitute.

  2. 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. 3

    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

Advice · (289) 805-2659

How do you know if my door is part of a fire separation?

The door and frame usually carry a small metal label stating the assembly's rating, and the building's own fire safety plan or a previous inspection report will identify which doors are part of a fire separation. If a label is missing or unreadable, that is worth raising with your building's fire safety plan holder before hardware is chosen, since it changes what can legally go on the door.

Does an electric strike need to match a specific lock function?

Yes. An electric strike has to suit the latch or deadlatch type it will receive, the door's handing and swing, and whether the application needs fail-safe or fail-secure operation, meaning whether the door should unlock or stay locked if power is lost. Choosing a strike without checking these against the mechanical lock is a common reason a door releases electronically but still binds mechanically.

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

38%

Homes of every age. About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.

In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.

37%

Single-detached houses make up about 37% of homes in Mississauga (2021 Census).

Where housing is mostly apartments and condos, mailbox locks are a regular call. A worn or lost mailbox key is a small job that a locksmith handles alongside the suite door, and the new lock comes with fresh keys cut on the spot.
