Commercial Rekeying in Sonya
You have just signed the lease on a unit the previous tenant ran for a decade.
In plain words
Losing a master key exposes every door it opened, and a commercial rekey brings that exposure back to zero. The locksmith first works out which level the missing key sat at: a single change key affects one or two cylinders, while a master reaches every lock in its group. Only the affected cylinders are repinned, which keeps the rest of the system intact and the response proportionate. Where a keying chart exists the work is precise; where the chart has been lost, the visit begins by reading and recording the existing cylinders so the new plan starts from facts rather than memory.
How the visit goesYou have just signed the lease on a unit the previous tenant ran for a decade. The landlord handed over three keys, the back door wears a padlock nobody can open, and nobody can say how many front-door keys are still out there.

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.
Keys counted into named hands
Alongside the chart comes a key register: each key's stamped code, the person it was issued to, the date, and a line for the date it comes back. Filling it in as keys are handed out on the first morning takes ten minutes and pays off at every departure afterwards, because the question becomes 'return key A-07' rather than 'did she have a key?'. Spare keys are counted too and kept somewhere locked rather than in the drawer where the old tangle lived. When the register and the chart agree with the keys on the hook, the business knows exactly who can open it, which is the whole point of the exercise.

What affects the quote
Several locations
Rekeying two or three sites onto one keying plan means travel between them and a chart that spans buildings, quoted per site plus the shared design work.
Mix of lock types
A key-in-lever cylinder, a storefront mortise cylinder, a back-door rim cylinder and a padlock take different handling, though several full-size formats can share one pin kit for the same key system; a premises with a wide mix of cylinder types and brands still takes longer than one with one.
Doors out of alignment
A door whose cam, strike or closer needs adjusting so the freshly rekeyed cylinder throws the bolt fully is corrected during the visit, and that adjustment is a separate item.
What to have ready
- Does your lease say anything about changing locks or giving the landlord a key?
- How many keys do you need cut, and for whom?
- Do you have a current list of who holds keys?
Commercial Rekeying: questions
QuestionsWe are a landlord with a tenant leaving. When should the unit be rekeyed?
Between tenants is the ideal moment: the departing tenant has handed back their keys, the new one has not yet received any, and the unit is empty for the work. The incoming tenant then starts on keys nobody else has held, and the landlord's own master or emergency key is set up at the same time. Where a lease has ended in dispute, the locksmith asks to see the paperwork before changing locks on a unit that still holds a tenant's goods.
What is a master key system and does a small business need one?
In a master key system each lock accepts its own change key and also a master key above it, so a manager carries one key while staff carry keys that open only their own doors. Small businesses with three or four doors often manage without one. A master earns its place once there are several rooms with different people in them, or several locations, and the owner would otherwise carry a ring of keys.
What is the difference between rekeying a business and replacing its locks?
Rekeying keeps every lock on the door and changes only the pins inside the cylinder, so a new key works and the old ones stop. Replacing swaps the hardware itself. Commercial cylinders are made to be repinned many times, so rekeying suits any lock in sound condition and leaves the levers, trim and door untouched. Replacement is chosen door by door for cylinders that are worn, corroded or too light for what they protect.
