Commercial-Grade Lock Replacement in Normanhurst
An inspection report flagged the rear exit as needing hardware that opens with one motion and no key, and that door currently has an ordinary keyed knob on the inside.
In plain words
Businesses often reach this service after something specific happens: a break-in, a departing employee holding a working key, a lease turnover, or an inspector's note about the rear exit. Whatever the trigger, the work itself follows the same order. The locksmith assesses the door and its current hardware, agrees with an authorized contact on the keying the new lock should follow, fits hardware rated for the opening's construction and use, and connects it to anything else already wired into that door, such as an alarm contact or an access-control reader, before testing and handing the keys over.
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.
Preserving the door's required behaviour
On a door required to close and latch on its own, the new hardware is installed and the closer adjusted so that behaviour still happens after the work is done: the door swings shut, the latch engages, and nothing about the new lock lets it be secured open in daily use. On an exit route where listed push-type hardware is required, the entire route from that door to the outside is checked so the new hardware fits the same standard as the rest of the path rather than becoming the one mismatched link in it.
Electrified hardware working as one system
If the door carries an electric strike, a maglock or a card-reader tie-in, that hardware has been tested together with the new mechanical lock rather than left to be sorted out separately. The release button, the reader and the mechanical latch now agree with each other, so staff are not shouldering a door that is supposedly already unlocked. Anyone monitoring the door through an alarm panel or access-control software can confirm the contact reports correctly against the new hardware.

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.
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.
Number of doors involved
One entrance is the simplest case. Bringing several doors, or several branch locations, onto matching hardware or one key system in the same engagement is priced across the whole set rather than door by door in isolation.
What to have ready
- Is this one door, or part of a wider multi-door or multi-branch project?
- What is currently installed: a knob, a deadbolt, a mortise lock, or an exit device?
- Has the door recently been forced, damaged, or shown signs of a break-in?
Commercial-Grade Lock Replacement: questions
QuestionsDo you handle interchangeable-core (IC) cylinders?
Yes. An interchangeable-core cylinder lets an authorized key holder pull the core and swap in a new one when a key needs retiring, without removing the whole lock from the door. Businesses with regular staff turnover often move to this system because it turns a rekey into a short in-house task rather than a full service call every time.
Can you upgrade hardware without re-cutting the door or frame?
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.
Do you replace hardware after an attempted break-in even if the door still locks?
Yes, and it is worth having it checked even when the door still appears to function. A cylinder that was drilled at, pried or struck can be weakened internally without showing it externally, and a bent strike or a cracked frame around the lock can let a door appear locked while offering far less resistance than it should.
