Commercial-Grade Lock Replacement
Overnight someone forced the back door, and the cylinder face is scarred, the metal around the strike has pulled loose from the frame, and the latch no longer sits flush.
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 goesAt 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.

How the visit goes


Checking how the current lock fits the business's key system
Every commercial building runs some kind of keying logic, even an informal one, and the locksmith maps it before touching hardware: is this cylinder on the same key as other doors, does it belong to a master or grand-master system, is it a standard keyway or a restricted one that only a specific supplier can cut? Getting this picture first means the new hardware can be ordered to slot into that structure, onto a fresh structure the business wants instead, or left standing alone if that is genuinely what is wanted.
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.
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
Site access and building type
A ground-floor storefront is the simplest case to reach and work on. A unit inside a larger building with its own access rules, or a site requiring coordination with building management, can add steps the quote takes into account.
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.
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.
What to have ready
- What is currently installed: a knob, a deadbolt, a mortise lock, or an exit device?
- Is the door part of a fire separation or a marked exit route?
- Is there an electric strike, maglock or card reader already on this door?
Commercial-Grade Lock Replacement: questions
QuestionsHow long does commercial-grade lock hardware typically last under heavy use?
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.
Can you replace just the cylinder instead of the whole lock body?
Often, yes, particularly with an interchangeable-core system where the core is designed to be swapped without removing the lock body from the door. Where the lock body itself is worn, damaged or of a grade that no longer suits the door's traffic, replacing the cylinder alone would leave the underlying problem in place, so the locksmith says which option actually fits the situation found.
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.
