Commercial-Grade Lock Replacement
The kitchen delivery door gets shouldered open more than a hundred times a shift, and lately the latch slips past the strike plate instead of catching it on the first push.
In plain words
For a business running several locations, this service is often less about one broken lock and more about bringing every door onto a single, manageable key or interchangeable-core system. The locksmith surveys what is currently on each door, works out a keying structure the business can actually administer, from a single master down to individual change keys, and replaces mismatched hardware with cylinders built to accept that structure. Keys are cut and logged against the new system, and any hardware still under a fire or egress rule is checked and matched to that rule at the same time.
How the visit goesThe 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.

How the visit goes


Weighing what the new hardware needs to do long term
The last part of the assessment looks past today's problem to how the business expects to manage this door going forward: does staff turnover happen often enough that an interchangeable core, which lets a key holder change the combination without pulling the whole cylinder, would pay for itself in convenience? Does the business want a restricted keyway so blanks cannot be cut at an ordinary hardware counter? These questions shape the specific hardware ordered as much as the door's physical construction does.
Matching the cylinder to the business's key system
The cylinder installed is the one agreed during the assessment: keyed into an existing master or grand-master system, set up as a new interchangeable core the business can rekey itself later, or cut to a restricted keyway that limits who can order duplicate keys. Where several doors are being brought onto one system in the same visit, cylinders are combinated so a single key or a defined set of keys operates every door that is supposed to share access.
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.
Fire-rated or listed hardware requirements
A door that is part of a fire separation needs hardware listed for that specific rating, which is a narrower and typically costlier category than general-purpose commercial hardware, and the quote reflects that requirement rather than a standard substitute.
Restricted or patented keyways
A restricted keyway usually costs more as hardware than a standard cylinder, and duplicate keys are controlled through the manufacturer or distributor rather than cut freely; some restricted programs require formal registration, while others control the same blanks without a signed authorization step.
What to have ready
- Do you have a record of the current keying or key-control log?
- What is currently installed: a knob, a deadbolt, a mortise lock, or an exit device?
- Do other doors on the property share a key with this one?
Commercial-Grade Lock Replacement: questions
QuestionsCan 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.
Do 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.
Will replacing the lock affect my alarm or access-control system?
It can, if the door already carries a door position switch, an electric strike or a card reader, so the locksmith checks for that wiring before starting and reconnects and tests it alongside the new mechanical hardware. The goal is a door where the mechanical lock and the electronic system agree with each other rather than one working around the other.
