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

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.

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.

How the visit goes

Illustrative locksmith scene — Coverdale
  1. Scene 1

    Assessing damage from a break-in or forced entry

    When the reason for the call is a forced door, the locksmith treats the assessment a little differently: documenting a scarred cylinder, a bent strike or a cracked frame for the business's own records or insurance purposes before removing anything. The door and frame are checked for structural damage beyond the lock itself, since a replacement lock fitted into a damaged strike pocket or a split frame will not hold the way new hardware should. Anything beyond the lock itself is noted as its own repair.

  2. Scene 2

    Connecting any electrified or access-control hardware

    Where the opening already carries an electric strike, a maglock, a door position switch or a card-reader tie-in, that wiring is reconnected to the new mechanical hardware and tested together rather than assumed to still line up. Voltage, fail-safe or fail-secure operation, and monitoring contacts are confirmed against what the access-control or alarm system expects, since electrified hardware that is almost, but not quite, matched to the mechanical lock is a common source of a door that buzzes open but still needs force.

  3. Scene 3

    One key system instead of a patchwork

    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.

  • Key cutting and coding machine
  • Key-control log and tags

What shapes the quoteCobourg Lock & Key Co.

Interchangeable-core hardware
Interchangeable-core cylinders cost more up front than standard ones but reduce the cost of every future rekey, since the business can swap cores itself. Whether that trade-off suits you shapes which cylinder type is quoted.
Key-control documentation
Setting up or updating a written key-control log, recording who holds which key and which doors share a system, is a small but distinct task the quote can name separately from the physical hardware work.
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.

Short answers to common questions

Do you match hardware to my building's existing key system?

Yes, that is usually the first decision made. The locksmith checks whether your doors already run on a master or grand-master system, an interchangeable-core setup, or a restricted keyway, and orders replacement cylinders that slot into whichever structure you want to keep or move to. Bringing a new door onto an existing system is generally simpler than starting that door on its own.

Who should hold the master key once the system is set up?

That is a decision for the business, not the locksmith, but the general practice is to limit master keys to the smallest number of people who genuinely need building-wide access, and to log who holds each one. Sub-master and change keys can then cover departments, shifts or single doors without every key holder carrying access to everything.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 52 in 100 homes · older homes
  • About 52% of homes in Cobourg were built in 1980 or earlier, according to the 2021 Census.Where housing is mostly older, many entries still have only a knob lock and no deadbolt at all. Adding one is a straightforward job on a solid wood door, and it is the single upgrade that changes most for a house of this kind.
  • Single-detached houses make up about 58% of homes in Cobourg (2021 Census).In areas of mixed housing, landlords may own a house here and a few units there. A locksmith can put all of it under one master system so the owner carries one key while each tenant's key opens only their own door.
