- The call
- 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.

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.
Commercial-grade lock replacement swaps hardware that is worn, damaged, mismatched or simply not rated for a business door with hardware built for that duty: a mortise lock body, a heavy cylindrical lockset, or a narrow-stile lock or hookbolt for an aluminum storefront door. The locksmith reads the door's construction, the traffic the opening takes, and any key or access-control system already running before choosing a replacement. New hardware is keyed into that existing system rather than left to stand on its own, so one business ends up with one coherent set of locks instead of a patchwork of whatever was fitted door by door over the years.

Commercial-Grade Lock Replacement · Mount Albert

Scene 1
The door tells the locksmith what kind of hardware it can even accept. A hollow-metal or solid wood door with a mortise pocket cut into the edge takes a mortise lock body; an aluminum storefront door with a narrow stile takes a purpose-built narrow-stile lock or hookbolt; a standard cylindrical bore takes a heavy-duty lockset sized to that hole pattern. Handing, swing, backset and existing strike location are measured so the replacement drops into the prep that is already there rather than requiring the door itself to be re-cut.
Scene 2
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.
Scene 3
Where the visit brought hardware onto a shared master or interchangeable-core system, the business now has one coherent structure instead of a different cylinder on every door. A master key opens what it is supposed to, sub-master and change keys are limited to their own doors, and the key-control log reflects exactly who was issued what. The next time a lock needs attention, whoever handles it can read that log rather than guessing at what system, if any, the previous hardware belonged to.
What shapes the quoteBrown Hill Locksmith Specialists
FeesSame any hour
It depends heavily on cycle count and how the door is treated day to day, but hardware graded for commercial duty is built to outlast the internal wear that sinks a residential lock on the same door. A delivery door opened hundreds of times a shift will still wear its hardware faster than a quiet office entrance, so grade and use should be matched from the start rather than assumed.
In most cases, yes. Replacement hardware is chosen to fit the door's existing mortise pocket, bore pattern or narrow-stile prep, so the visit does not usually involve altering the door itself. Re-cutting only comes up when the business specifically wants to change hardware type, for example moving from a knob-and-deadbolt pair to a single mortise lock body.
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.
