In plain words

For most business doors, rekeying is the sensible middle path between doing nothing and buying new hardware. Commercial cylinders are built to be repinned many times, and a lever set, mortise lock or storefront cylinder in decent condition has years left in it. Rekeying keeps the finish, the door preparation and the handles you already have and changes only the small brass pins inside. Where a cylinder is worn, corroded by winter salt or too light for the room behind it, the locksmith says so and offers a replacement for that door alone; the rest are rekeyed to the new plan.

Sound familiar?

You 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

  1. 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.

  2. 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.

  3. A routine for the next departure

    Turnover stops being a security event once there is a procedure for it. When someone leaves, their key is collected against the register and ticked off; if it cannot be produced, the chart shows exactly which cylinders that key opened, and only those are dealt with. Businesses that chose interchangeable cores can go further: the manager takes the control key from the safe, swaps the affected core for a spare in less time than a coffee break, and the locksmith repins the removed core at leisure for the next time. Either way the response is measured and specific, and the front door is never left answering to a key that walked out with a former employee.

What affects the quote

  1. 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.

  2. A master key plan

    Pinning cylinders to accept both a change key and a master, and designing the chart so no key opens a door it should not, is more work per cylinder than keying everything alike.

  3. Padlocks, cabinets and mailboxes

    Small locks add up. Each padlock repinned to the door key, each cabinet keyed alike and each mailbox cylinder replaced is listed on its own so you can decide what to include.

What to have ready

  • Do you have a current list of who holds keys?
  • Can you gather every existing key so they can be read on site?
  • When is the premises quiet or empty enough for the work?

Commercial Rekeying: questions

Questions
Will every old key stop working once you are done?

Every old key that operated a cylinder included in the plan will stop working, and the locksmith proves it by trying old keys at each door before leaving. Old keys keep working only at openings you chose to leave alone, which are written on the chart so there is no confusion. If a master key existed, it is tested too, since a forgotten master is the most common way an old key stays alive.

Should we rekey every time an employee leaves?

Rekey when a key has not come back or when the departure was unfriendly; when a key is returned and the register confirms it, the cylinders it opened are as secure as before. Businesses that want a response to every departure without a visit each time fit interchangeable cores and swap them in-house. Whatever the trigger, dealing with only the cylinders that key opened keeps the response proportionate.

Can the aluminum storefront door on our unit be rekeyed?

Yes. The narrow stile of a storefront door houses a screw-in mortise cylinder secured from the edge, and it unthreads, is repinned and screws back in like any other. What the locksmith watches is the cam: it has to suit the hook or deadbolt mechanism inside the door and sit at the correct depth, or the bolt throws short. Weather-facing cylinders showing salt wear are pointed out so you can decide on replacement.
