Commercial-Grade Lock Replacement in Scarborough Village
Overnight someone forced the back door, and the cylinder face is scarred, the metal around the strike has pulled loose from the frame, and the latch no longer sits flush.
In plain words
Fire separations and exit routes add a layer that a house entry door never has, and this service is where that layer gets handled properly. A door that forms part of a fire separation needs hardware listed for that door's rating, and a door on a required exit may need to open with a single motion and no key once the building's occupant load crosses a threshold. The locksmith checks whether either condition applies to this specific opening, selects hardware that satisfies it, and installs the new lock so the door still closes and latches the way a fire-rated or exit door is required to.
How the visit goesHead office wants every branch keyed alike under one system, and half the locations are still running whatever lockset the original contractor happened to install years ago.

How the visit goes


Looking at how the opening is actually used
A door's traffic shapes which hardware belongs on it. A staff entrance opened a handful of times a day tolerates lighter-duty hardware than a delivery door shouldered open on every shift, and a customer-facing storefront door needs a finish and function that hold up under public use. The locksmith asks how often the door opens, who uses it, and whether it is propped, wedged or held open in daily practice, since a door habitually held open needs hardware and a closer arrangement that account for that use rather than fighting it.
Matching the cylinder to the business's key system
The cylinder installed is the one agreed during the assessment: keyed into an existing master or grand-master system, set up as a new interchangeable core the business can rekey itself later, or cut to a restricted keyway that limits who can order duplicate keys. Where several doors are being brought onto one system in the same visit, cylinders are combinated so a single key or a defined set of keys operates every door that is supposed to share access.
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
Timing relative to a lease or renovation
Work scheduled around a tenant turnover, a renovation, or a building-wide upgrade across several units can be planned and quoted as a coordinated project rather than a series of separate calls.
Number of keys cut and issued
Keys are counted individually into the quote. A small office needing a handful of keys is a smaller line item than a multi-shift operation issuing keys to a large staff roster.
Condition of the existing door and frame
A door and frame in good condition accept new hardware into the existing prep with little extra work. Damage from a break-in, a cracked frame or a previously mis-cut mortise pocket adds repair time the quote accounts for separately.
What to have ready
- Roughly how many times a day does this door open?
- Do other doors on the property share a key with this one?
- Do you have a record of the current keying or key-control log?
Commercial-Grade Lock Replacement: questions
QuestionsWhat 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.
How does this service differ from a home lockout or residential rekey?
A home lockout or residential rekey is usually about one door and one household's keys. Commercial-grade lock replacement more often involves a system, several doors, a master key structure, and sometimes a fire or exit rule the door has to satisfy, so the assessment, the hardware selected and the record kept at the end are all built around managing that wider structure rather than a single lock.
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.
