Commercial Rekeying
The office has been reshuffled twice since the locks were last touched.
In plain words
Taking over a commercial unit is the moment to make the locks yours. The keys handed across at signing are only the ones the previous occupant remembered; cleaners, suppliers and former staff may still carry others. Rekeying every cylinder your lease gives you control of gives you a clean start on day one, with keys cut for your team and a chart of which door each one opens. The locksmith also clears up the odds and ends that come with a new lease: a padlock with no key, a mailbox lock seized since the last tenant. You open knowing exactly who can get in.
How the visit goesA break-in overnight took the cash float and a staff member's bag with her work keys inside it. The glass is being replaced this morning, but the key that opened the door yesterday will still open it tonight unless the cylinders are changed.

How the visit goes
Choosing the window and the order of doors
The last part of the assessment is practical: when can the work happen, and in what order. A retail shop may prefer the hour after closing; a restaurant, the mid-morning lull; a warehouse, the gap between the last outbound truck and the night shift. The locksmith also asks about deliveries, the cleaning crew, the alarm monitoring company and anyone else who holds a key and needs a new one before their next visit. From this comes a sequence, typically the doors staff use least first and the main entrance last, so there is always a working, lockable way in and out while the cylinders are being changed.
Cutting and marking the new keys
Keys are cut to the new combinations on a code machine rather than traced from another key, so every copy is exact and the tenth key fits as cleanly as the first. Each key is stamped with a short code that means something only on the keying chart; the business name, the address and the word for the door it opens stay off the metal, so a lost key gives nothing away. Keys are counted out by group, tagged, and listed against the names of the people who will carry them. Where the plan uses a restricted keyway, the blanks are drawn against the authorization letter, and that letter is filed with the chart for future orders.
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
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.
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.
Upgrades chosen on the day
Some businesses use the visit to move to interchangeable cores, add a lockbox for the alarm company or fit a heavier cylinder on the cash room. Each is a separate line you can accept or leave.
What to have ready
- Are any cylinders stiff, loose or hard to turn at the moment?
- Can you gather every existing key so they can be read on site?
- Which doors, if any, belong to the landlord or a shared corridor?
Commercial Rekeying: questions
QuestionsCan all our doors be put on a single key?
Yes, if the cylinders share a keyway or can be fitted with ones that do. Keying everything alike is popular with small shops because staff carry one key and spares are simple. The trade-off is that one key then opens the cash room as readily as the front door. Many businesses choose a middle path: the doors everyone uses on one key, the sensitive rooms on another, and an owner's master that opens both.
What do you do with the old keys?
They are gathered, tested at each rekeyed door to confirm they no longer work, and then cut through so they can never be used or copied. You can keep the pieces or the locksmith takes them away. Any old key that still operates a door you chose to leave unchanged is handed back and noted on the chart, so it is clear which keys remain live and which are scrap.
Is a restricted keyway worth it for a business?
A restricted keyway uses blanks that only the locksmith or authorized source can obtain, released against whatever that key-control program requires, a signed letter, card, signature record or factory authorization naming who may order keys. Hardware stores and kiosks have no blanks, so copies are far harder to get without your say-so. It costs more per key than a standard keyway and is most valuable where keys pass through many hands, such as retail with part-time staff, shared premises or anywhere the count of copies has drifted before.
