Lock Rekeying

The previous owners left a coffee tin of keys on the counter, some labelled, most not. The house is yours now, but you have no idea how many copies were cut over the years or who still has one in a drawer somewhere.

In plain words

Moving into a home is the moment most people first hear about rekeying, and it is the most sensible time to do it. A resale house has usually passed through owners, real estate agents, home inspectors, cleaners and trades, each of whom may have held a key at some point. Rekeying every exterior cylinder on move-in day means the only keys that work are the ones cut for you, and the same visit is a chance to put every door on one key so the coffee tin of mystery keys can go in the recycling.

Sound familiar?Hamilton

The call
Your roommate moved out last weekend. Rent is settled, the room is empty, and the key is still on their ring. You trust them, but the lock on your front door should answer to the people who actually live here.

How the visit goes

Illustrative locksmith scene — Hamilton
  1. Scene 1

    Doors that belong to someone else

    A few openings around a home are not the occupant's to change, and sorting them out early avoids awkwardness later. In a condominium, the lobby, the garage, the locker room and the mailroom are the corporation's doors, and the suite door itself may need to remain on a system the building can access in an emergency. In a rental, the landlord has a say and must be given a key. A shared side entrance in a semi-detached or a duplex serves two households. The locksmith asks about each of these, confirms who needs to agree, and keeps them separate from the doors that are plainly yours.

  2. Scene 2

    Cutting the new key and gauging the depths

    On this cylinder type, the new key comes first, then the pins to match it. The locksmith cuts a fresh key from a blank on a code cutter or duplicator, choosing a combination that is not close to the old one, and reads each cut with a key gauge to find its depth on the manufacturer's scale. Bottom pins of the matching lengths are picked from a graded pin kit and dropped into the plug chamber by chamber, so that when the new key is inserted every pin top sits exactly at the shear line. A key cut from a clean blank and pins matched to it by gauge is what gives a rekeyed lock that crisp, new feel.

  3. Scene 3

    Knowing when to rekey again

    Rekeying is not a once-in-a-lifetime event; it is a habit tied to changes in who holds keys. The moments to think about it are the same ones that brought you here: a move, a tenant or roommate change, a key lost with anything identifying the address, a contractor who has finished, or a relationship that has ended. Between those events there is nothing to schedule. Because the house is now on a known system with a record, a later rekey is a shorter visit, and any new lock you add along the way can be pinned to the existing key so the household never drifts back to a ring full of mismatched keys.

What shapes the quoteCobourg Lock & Key Co.

Smart lock override cylinders and codes
Pinning the backup cylinder of a keypad or app lock to the house key is a small extra task, and reviewing or deleting user codes at the same time is another, each named in the quote.
Mailboxes, padlocks and cabinets
Small cam locks on mailboxes and cabinets are usually replaced rather than repinned, and padlocks vary in whether they can join the house key; each of these is priced as its own item.
How many cylinders are included
Each cylinder is removed, pinned and tested on its own, so a single deadbolt and a house with six exterior locks plus a shed and a gate are very different visits, and the quote follows the count.

Short answers to common questions

What happens to my old keys?

They become ordinary pieces of brass. Once the cylinders are pinned to the new combination, the old keys turn nothing on your property, so there is no security reason to keep or hide them. Hand them to the locksmith for disposal or drop them in the metal recycling. If a former roommate or contractor still has one, it no longer matters, which is the whole reason for the visit. Keep only the new set, counted and tagged.

What should I have ready before the locksmith arrives?

A list of the doors you want included, a working key for each lock if you have one, and a clear idea of whether you want everything on one key or some doors kept separate. Have your identification and something tying you to the address handy. If you rent, have your landlord's agreement ready to mention. Knowing roughly how many new keys the household needs saves a second trip to cut more.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 55 in 100 homes · older homes
  • About 55% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.
  • Single-detached houses make up about 95% of homes in Hamilton (2021 Census).Detached homes are exposed to weather on every side, so exterior locks see rain, salt and freezing air directly. Choosing hardware with a good finish and a cylinder that tolerates cold, then lubricating it properly, keeps every door turning through winter.
