- The call
- 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.
A new tenant moved into the unit next door, and the property manager just found three different cylinders on three doors, none of them cut to the same key.
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
Scene 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.
Scene 2
Removing the old hardware cleanly
The existing lock, cylinder and strike come out without enlarging the door's mortise pocket or bore, since a clean prep is what lets the new hardware seat correctly. Any hardware that was previously mismatched to the door, an incorrect backset or a strike screwed in at an angle, is noted so the business understands why the last repair may not have held. The old hardware is set aside for the business to keep, dispose of, or use as a reference for other doors still running the same outdated lockset.
Scene 3
Fire and exit requirements satisfied, not just noted
Where the door forms part of a fire separation or a required exit route, the new hardware is listed for that use and the door has been tested to confirm it still closes and latches on its own. Any push-type release hardware installed to meet an occupant-load threshold has been checked across the whole route it serves, not just at the one door where the call started. The business leaves with an opening that satisfies the condition that triggered the work, rather than a lock that merely looks similar to what was there before.

What shapes the quoteBox Grove Locksmith Pros
- Panic or exit hardware
- Listed exit devices cost more than a standard lockset and are quoted per opening, since a route requiring this hardware often needs it consistently across more than one door along that path.
- Coordination with other trades or systems
- Where a door closer, an alarm panel or a building-wide access-control platform is involved, coordinating the lock replacement with whoever manages those systems can add planning time that the quote reflects.
- 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.

Frequently asked questions
What should I do with the old hardware once it is replaced?
That is entirely your choice. Some businesses keep old hardware briefly in case a spare part is needed elsewhere on the same system, others prefer it removed from the site straightaway, particularly after a break-in where the damaged pieces are no longer wanted around. The locksmith can leave it with you or take it away, whichever you prefer.
Can you install a restricted or patented keyway?
Yes. A restricted keyway limits duplication to keys cut through the manufacturer or an authorized distributor rather than at an ordinary hardware counter, though the exact registration and proof-of-entitlement steps vary by system; a patent-protected keyway adds a further, legally backed layer of control on top of that. This is a common step for a business tightening key control after a lost key or staff turnover.
What happens to keys held by former employees or contractors?
Once a cylinder is replaced or rekeyed, any key that was not reissued for the new combination simply stops working on that door. This is the direct answer to a key that walked out with someone who left the business, and it is worth doing across every door that key used to open, not only the one that prompted the call.

2021 census: what it means at the door
Every square is one home in a hundred.
- 19 in 100 homes · newer homes
- 56 in 100 homes · mixed housing
- About 19% of homes in Markham were built in 1980 or earlier, according to the 2021 Census.In newer developments the hardware is often the same finish and style from house to house. A locksmith can offer upgrades that match what is already there, so a stronger cylinder or a new lever set fits in without looking like an afterthought.
- Single-detached houses make up about 56% of homes in Markham (2021 Census).Mixed housing brings mixed hardware ages as well as types. A locksmith may rebuild a mortise lock on a semi-detached house and then set up a keypad on a townhouse door across the road, and treats each with the care its owner expects.
