Commercial-Grade Lock Replacement in Unionville
The 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.
In plain words
Think of it as re-equipping a door for the job it actually does rather than swapping one lock for a similar one. A back door taking deliveries all shift needs different internals than a quiet office entrance, and a storefront's aluminum frame needs a narrow-stile lock a wood door was never built to accept. The locksmith matches lock body, cylinder and strike to the door's real prep and real use, decides with the business whether the new hardware joins an existing master key system or starts a new one, and leaves the opening cycling cleanly from both sides before the visit ends.

How the visit goes


Checking how the current lock fits the business's key system
Every commercial building runs some kind of keying logic, even an informal one, and the locksmith maps it before touching hardware: is this cylinder on the same key as other doors, does it belong to a master or grand-master system, is it a standard keyway or a restricted one that only a specific supplier can cut? Getting this picture first means the new hardware can be ordered to slot into that structure, onto a fresh structure the business wants instead, or left standing alone if that is genuinely what is wanted.
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 door rated for the job it does
The business is left with hardware sized to how the door is actually used: a mortise lock body or heavy cylindrical lockset that can take the traffic of a busy entrance, or a narrow-stile lock built for the aluminum frame it is mounted in rather than adapted to it. Staff can be shown how the new hardware feels different from the old one, whether that is a firmer latch, a smoother deadbolt throw, or a different key profile, so nobody is caught off guard by hardware that behaves differently from what they are used to.

What affects the quote
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.
Key-control documentation
Setting up or updating a written key-control log, recording who holds which key and which doors share a system, is a small but distinct task the quote can name separately from the physical hardware work.
Keying complexity
A single stand-alone cylinder is the simplest keying job. A master or grand-master structure spanning multiple doors, departments or locations takes more planning and more cylinders to combinate correctly, and that planning is part of the quote.
What to have ready
- Do you have a record of the current keying or key-control log?
- Who can authorize the work and sign for new keys?
- Do you want a master key system, an interchangeable core, or a stand-alone lock?
Commercial-Grade Lock Replacement: questions
QuestionsDo exit devices need any ongoing attention after installation?
Yes. Exit devices and panic hardware are mechanical assemblies that see heavy use on a required exit, so periodic checking that the latch engages fully, the release bar moves freely, and any electrified or alarmed function still triggers correctly is worth building into the same schedule as other fire-safety equipment in the building.
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.
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.
