Commercial Rekeying in St. Williams
A key turned up in the parking lot with the shop's name on its fob.
In plain words
A business hands out keys as people join and rarely gets every one back as people leave. Rekeying resets that count. Instead of guessing how many copies of the front-door key exist, the cylinders are repinned so only the newly cut set works, and those keys are numbered and signed for. Where turnover is steady, the locksmith can fit interchangeable cores, which let a manager swap a core with a control key in a couple of minutes when someone departs, so the reset becomes routine rather than an event. Either way you end up with a premises where the keyholder list matches the staff list.
How the visit goesTwo people left over the summer and the keys they handed back came up one short. Nobody is sure whether the missing key was for the front door, the stockroom or both, and the sign-out sheet stopped being filled in a year ago.

How the visit goes


A walk of every door and lock
The locksmith walks the premises with you and lists every opening that should be in the plan: the customer entrance, the receiving door, offices, stockroom, cash room, server closet, the mailbox, cabinets, and any padlocks on gates, compounds or roll shutters. Each lock is identified by type, since a mortise cylinder in an aluminum storefront door, a key-in-lever set on an office, a rim cylinder on a back door and an interchangeable core in a stockroom each come out and go back in differently. The keyway and the maker's mark are noted, and the condition of each cylinder is checked, so the list from the walk is what the quote and the work are built on.
Padlocks, cabinets and the mailbox
A business is more than its doors, and the same visit brings the smaller locks into the plan. Rekeyable padlocks on the compound gate, the propane cage or the roll shutter can be pinned to the same key as the back door, so the opening crew carries one key instead of four. Filing cabinets, the till drawer, a medicine or chemical cupboard and the display cases can be keyed alike for the staff who use them or kept separate for the manager. The lobby mailbox, which often still answers to a key from two tenants ago, gets a fresh cylinder or is repinned where its design allows. Each small lock is added to the chart alongside the doors.
Telling the landlord and the alarm company
A rekey touches a few people outside the business, and the handover covers them. If the lease asks for it, the landlord or property manager receives a key to the suite entrance and a note that the locks were changed, which keeps you onside for emergencies and inspections. The alarm monitoring company is given the updated keyholder list, and it is a good moment to change the alarm codes of anyone who no longer works there, since a key and a code usually leave together. Cleaners, the courier with after-hours access and the neighbour who watches the place on holidays each collect their new key against the register like everyone else.

Commercial Rekeying
What affects the quote
No existing chart or keys
When nobody knows what the current keys open, the locksmith reads and records each cylinder before planning the new keying, and that reconstruction is time in the quote.
Documentation and register
A keying chart, a key register and stamped codes on every key are part of a proper commercial rekey, and the quote names the paperwork so it is never skipped.
Number of cylinders
The count of openings drives the quote more than anything else: each cylinder is removed, repinned, refitted and tested individually, so a three-door shop and a twelve-office suite are very different jobs.
What to have ready
- Which doors, if any, belong to the landlord or a shared corridor?
- Can you gather every existing key so they can be read on site?
- How many keys do you need cut, and for whom?
Commercial Rekeying: questions
QuestionsWhat happens with our fire exit doors and panic bars?
The outside cylinder on an exit door controls entry only, and it can be rekeyed like any other. The inside stays as it must: one push or one turn, no key, no special knowledge, on the exit door itself and on any door on the way to it. A locksmith will not add a keyed device to the inside of an exit, and will point out one if it already exists.
How do you confirm I am allowed to have the locks changed?
For a business the locksmith looks for someone with standing: the owner, a director, or a manager who can show written authority from one of them. A lease, a business registration or a letter on company paper usually settles it, along with photo identification. Where doors belong to a landlord, the property manager's approval is asked for as well. This is a short step and it protects the business from having its own locks changed by the wrong person.
We lost a master key. Does the whole building need doing?
Only the cylinders that master opened, which the keying chart identifies. If the lost key was the top master, that is every lock in the system; if it was a departmental master, it is that department's doors. Where no chart exists, the locksmith reads the cylinders first to establish what the key reached. The remaining doors, and any keys that never opened them, are left exactly as they are.
