Rekeying is a change made inside the lock rather than to the lock itself. Many keyed cylinders hold a row of small pins that have to sit at exactly the right heights before the plug will turn, set by the cuts on your key, though some residential cylinders use a side-locking bar instead of pins. A locksmith slides the plug out, removes the pins, and loads a new set matched to a freshly cut key. Reassembled, the lock looks and feels exactly as it did, except that the new key turns it and every key cut before today does not. Your hardware, finish and door stay as they were.
How the visit goesYour 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

- 1
Counting the keys that are already out there
Part of planning a rekey is understanding why it is happening. The locksmith asks how many keys exist as far as you know, who has held one, and whether any went missing with something identifying the address. The answers do not change the pinning, but they shape the advice: whether a padlock or mailbox shares the same risk, whether a garage keypad code should change on the same visit, and how many new keys make sense to cut. It also helps to know whether any key is a restricted or patented type, since those are cut from a record rather than duplicated and may involve the original supplier.

Sliding the plug and changing the pins
With the cylinder in hand, the locksmith removes the cam or tailpiece from the back, inserts the existing key and turns the plug slightly so the top pins clear, then pushes a plug follower in behind the plug as it slides out. The follower holds the top pins and springs in the housing so nothing springs loose. The plug now sits on the bench with its row of bottom pins exposed, and those pins are tipped out. This is the heart of rekeying a pin-tumbler cylinder: the pins that decided which key worked are gone, and the plug is ready to receive a set that matches a key nobody has ever carried.

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 affects the quote
- 1
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.
- 2
No working key for a door
When a cylinder must be shimmed, decoded or picked open before it can be repinned because no key exists for it, that extra step is included in the quote for that door.
- 3
Number of keys cut
Keys are cut and tested individually, so the total depends on how many the household or the tenants need. Say the number when you book and the quote reflects it from the start.

Lock Rekeying: questions
How long does a rekeying visit take?
It scales with the number of cylinders and how many need attention beyond pinning. A single deadbolt is a short bench job; a whole house with five or six exterior cylinders, a couple of swaps for mismatched keyways and a set of spares to cut and test takes a good deal longer. Tell the locksmith how many doors you want included when you book, and the visit can be planned realistically rather than guessed at.
Should I rekey when I move into a new home?
It is the single most common reason to rekey, and a sensible one. A resale home has typically passed through owners, agents, inspectors, cleaners and trades, any of whom may have had a key cut. A newly built home has been opened by construction crews using a builder's key. Rekeying on move-in means the only working keys are yours, and the same visit can bring every exterior door onto a single key, retiring the assorted keys you inherited.
My keys were lost with something showing my address. Is rekeying enough?
Rekeying is exactly the right response, because it makes the lost key useless at every door that was pinned. The locksmith will walk the property with you to be sure nothing is missed, including the garage side door, a shed and any padlock the same key opened, and will suggest changing any garage keypad code that was written on the same ring. After that, whoever finds the keys is holding brass that opens nothing on your property.

What the census means at the door
61%
Older homes. About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.
Old brass keys wear thin, and a key that has bent for years finally lets go in a cold cylinder. In older housing stock this is a regular call, so the locksmith is ready to extract the piece, check the cylinder and cut a new key from the code.
56%
A mix of homes. Single-detached houses make up about 56% of homes in Hamilton (2021 Census).
Where houses and attached homes share an area, lockouts are as varied as the doors. A porch, a hallway or a shared vestibule each calls for a slightly different approach, and a locksmith used to all three arrives ready for whichever it is.
