In plain words

Changing the locks answers today's question; key control keeps it answered. During a commercial rekey the new keys are stamped with a serial code rather than the business name or address, so a dropped key tells its finder nothing. Each key is logged against the person who receives it, and the old keys are collected and cut up on the spot. For premises that want copies kept out of hardware stores, the cylinders can be set up on a restricted keyway, with blanks released only against a signed authorization. What you end up with is a set of locks whose keys you can account for years later.

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

How the visit goes

  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. Door by door, never a gap

    The sequence agreed at the assessment is followed on the day. The locksmith finishes one opening entirely before beginning the next: cylinder out, repinned, refitted, tested with both the new key and the old, and locked again. Only then does the next door come apart. The main entrance is usually left for last and done while someone from the business is present, so there is never a moment when the premises has a door that will not lock. Staff who are working during the visit are handed their new key before the door they use is changed, and a short note goes to anyone off shift about where to collect theirs.

  3. Exits that still open the way they must

    Rekeying changes who can come in; it never changes how people get out. Every exit door and every door on the way to one is left opening from the inside with a single motion and no key. On a door with a panic bar, the outside cylinder simply controls entry, and the bar keeps working exactly as before. Once the locksmith has finished, walk the exit routes yourself, push each bar and turn each thumb-turn, and make that walk a habit at the start of every season so a new deadbolt or a helpful padlock never creeps onto an exit.

What affects the quote

  1. How many keys are cut

    Each key cut to code and stamped is counted into the quote. Two per door group for a small shop and forty for a warehouse shift are different numbers.

  2. 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.

  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

  • Do you have a current list of who holds keys?
  • How many doors, padlocks and cabinets do you want included, and where are they?
  • Are any of the locks interchangeable cores, and where is the control key?

Commercial Rekeying: questions

Questions
We 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.

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.

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.
