Lock Rekeying

Your roommate moved out last weekend. Rent is settled, the room is empty, and the key is still on their ring.

In plain words

Rekeying is really about knowing who can open your door. Over the life of a home, keys are lent to trades, handed to neighbours for the holidays, given to a cleaner or a dog walker, and copied at the hardware store. Nobody keeps a list. Rekeying draws a line: from today, the only working keys are the ones counted into your hand. Good practice afterwards is simple, and a locksmith will suggest it: know how many keys exist, know who holds each one, tag them with a colour or code rather than the address, and rekey again whenever a key leaves your control.

The call
One key for the front door, another for the back, a third for the side door into the garage, and a fourth for the shed. You stand on the step every evening flipping through them in the dark, trying each one until something turns.

How the visit goes

  1. Scene 1

    Smart locks and user-rekeyable cylinders

    Modern hardware gets its own look. Many keypad or app-controlled deadbolts have a conventional override cylinder behind a cover that can be rekeyed to the house key so the backup key is not a stranger on your ring, though some models are key-free and use an external battery backup instead. Some residential cylinders are designed to be reset by the owner with a small tool and a working key; the locksmith checks whether one has been reset correctly and whether it accepts the new key. Where a smart lock is being kept, codes are reviewed at the same time so a departed keyholder's code goes the way of their key.

  2. Scene 2

    Proving the old keys are finished

    The last operation at every door is the test that matters most. The locksmith turns the new key from outside and inside with the door open, then closed, and confirms the bolt throws fully and draws back cleanly. Then the old key is tried in the same cylinder and must turn nothing. This is repeated at every rekeyed door, because the door that gets skipped is the one an old key still opens. Spares cut from the new pinning are tried in every lock they are meant for. The old keys, now just shaped brass, are collected or handed back to you for the recycling bin.

  3. Scene 3

    Living with one key for the house

    If the visit brought your doors onto a single key, daily life gets a little simpler: one key opens the front door, the back, the garage's side entry and the shed, and the ring in your pocket shrinks to the car key and one for the house. Anyone you give a key to gets the same freedom, which is convenient for family and worth thinking about for anyone who should only reach one door; that is what a separate group is for. Keypads and smart locks keep their codes, and their override cylinder now takes the same key. If you add a door later, its cylinder can be pinned to match.

What shapes the quoteBuchanan Lock Services

Restricted or high-security cylinders
Patented keyways use controlled blanks and pins that cost more than standard ones, and their keys are produced from a controlled record instead of being copied, so a system of that kind is quoted differently from builder-grade hardware.
One key group or several
Keying every door alike is the simplest plan. Setting up separate keys for a basement suite, an office or a shed adds a group to pin and label, and the quote shows that as separate work.
Several units in one building
A landlord rekeying a duplex, a triplex or a small apartment building, with each suite on its own key and a common entry shared, has more cylinders and a keying chart to build, and the quote grows accordingly.

What to expect, answered

Do the old keys really stop working?

Yes, at every cylinder that was rekeyed. Once the bottom pins are changed, a key cut to the old combination lifts them to the wrong heights and the plug will not turn. The locksmith proves this at each door by trying the old key after the new one, because any door missed from the list would still answer to the old key. That is also why the walk around the property at the start matters: every door meant to be included has to be on the list.

What exactly does rekeying a lock change?

What changes depends on the cylinder. Many locks turn when a row of small bottom pins lines up at a precise level, set by the cuts on your key, and during a rekey the locksmith tips those pins out and loads a set that lines up with a different key, cut new for you; some residential cylinders instead reset a side-locking bar without removing any pins. From then on the new key operates the lock and older keys do not, and the hardware on the door stays as it was.

How many new keys will I get, and can I get more later?

As many as you ask for, cut on site from the fresh pinning and tested in each door they should open; two or three is typical for a household. More can be cut later. When you do, bring one of the locksmith's originals to be copied rather than a copy of a copy, since every generation strays slightly from the intended depths. If any key is a restricted type, additional copies come from the record kept for that system rather than from a hardware store.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 61 in 100 homes · older homes
  • About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Where most homes were built decades ago, doors often still carry their original mortise locks and brass knobs. That hardware can usually be cleaned, re-sprung and kept in service, with a modern deadbolt added above it for strength without losing the look.
  • Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
