Commercial-Grade Lock Replacement in Lisgar
At closing time the hookbolt on the storefront door catches the keeper only on the second or third try, and one employee has started giving the door a shoulder to force it home.
In plain words
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 goes


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.
Cutting keys and updating the record
New keys are cut to the agreed system and tested in every door they are meant to open before anyone leaves the site. Where a master or interchangeable-core system is involved, the locksmith updates the business's key-control log with what was issued, what was retired, and which doors now share which key, so the paper record matches the metal. Any key that was reported lost or held by someone no longer with the business is confirmed as no longer functional on the new hardware.
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
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.
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.
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.
What to have ready
- Do you want a master key system, an interchangeable core, or a stand-alone lock?
- Is there an electric strike, maglock or card reader already on this door?
- Roughly how many times a day does this door open?
Commercial-Grade Lock Replacement: questions
QuestionsWhat information should I have ready before the visit?
It helps to know roughly what is on the door now, knob, deadbolt, exit device or something else, whether other doors on the property share a key with it, and who in the business can authorize the work and sign off on keys. Photos of the current hardware and any fire label on the door are useful if you can get them ahead of time.
Is panic hardware the same as fire exit hardware?
Related but not identical. Panic hardware allows single-motion release without a key on any qualifying exit door. Fire exit hardware does the same job on a door that is also part of a fire separation, and it is listed for that combined use with no mechanical hold-open feature, since a fire door has to be able to close and latch on its own at all times.
My storefront door is aluminum and glass. Does it need special hardware?
Yes. An aluminum storefront door has a narrow stile, the vertical metal frame around the glass, that a standard mortise or cylindrical lock cannot physically fit into. These doors take a narrow-stile lock or a hookbolt built specifically for that slim profile, and matching the hardware to the frame is what lets the bolt engage the keeper fully instead of catching at an angle.
