A key turned up in the parking lot with the shop's name on its fob.

In plain words

Commercial rekeying changes the pins inside a business's existing lock cylinders so that a new key operates them and every earlier key stops working, while the hardware itself stays on the door. The locksmith works from a list of the openings the business controls and the people who need to pass through each one, sets the cylinders to fresh combinations, cuts keys to match and records which key opens which door. Because nothing is replaced unless it is worn, a whole premises can be brought back under control in one scheduled visit, with the doors locking and unlocking exactly as before but answering only to keys you have counted.

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.

  1. Reading the keys that already exist

    Before deciding anything new, it helps to understand the old. Gather every key the business can find, including the ones with faded tape labels, and the locksmith reads them against the cylinders on the walk. Some will turn out to be duplicates of each other, some will belong to hardware that was replaced years ago, and some may operate doors nobody expected them to. Hardware-store copies stand out by their blanks and by the way they wear. This reading shows how far the key count has drifted and whether an old master still exists, and it lets the new plan retire everything found in the drawer rather than only the keys anyone remembered.

  2. 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.

  3. Storefront hardware ready for the salt

    Cylinders on a street-facing door live a hard life: slush, salt spray from the sidewalk plough and a dozen freeze-thaw swings a winter. Each cylinder handled during the rekey is cleaned and dressed with the lubricant approved for that model, a dry graphite, PTFE or specified liquid lubricant applied sparingly, since too much graphite can gum a cylinder just as oil traps grit. Keep it that way with a puff of the same lubricant each autumn and a wipe of the key before it goes in on a slushy morning. A set screw snugged, a cam aligned and a bolt that throws fully are part of the handover, so the rekeyed door also locks more cleanly than it did before.

What affects the quote

  1. 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.

  2. 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.

  3. Restricted keyway

    Moving to a patented, restricted keyway means new cylinders or cores rather than a repin of the old ones, and the blanks themselves carry a higher price than standard keys.

What to have ready

  • How many keys do you need cut, and for whom?
  • Are any of the locks interchangeable cores, and where is the control key?
  • How many doors, padlocks and cabinets do you want included, and where are they?

Commercial Rekeying: questions

Questions
What 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.
