Lock Rekeying
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.

For landlords and tenants, rekeying is the tidy way to handle a change of occupancy. A departing tenant may have copied a key or simply forgotten to return one, and a fresh pinning means the incoming tenant is the only person holding a working key. Tenancy rules in this province expect a landlord who changes locks to give the tenant a replacement key and a tenant to have the landlord's consent before changing them, so a locksmith asks who is requesting the work and makes sure both sides end up with a key. A small record of the doors and key count keeps everyone clear.
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.

Resetting a user-rekeyable cylinder properly
Some residential deadbolts and handle sets are built so the owner can change the key with a small tool, a working key and the new key. They save a bench session, and they also go wrong in a particular way: without a working key of the correct type, or with a key from the wrong keyway, the reset stalls partway. The locksmith carries the reset tool and the reset procedure for these cylinders, confirms the keyway matches the new house key, and completes the change so the cylinder accepts the new key and rejects the old one. If the mechanism has been damaged by a forced reset, it is replaced with a standard cylinder and pinned to match.

Handing keys out with a little method
Rekeying gives you a clean start on who holds a key, and a few habits keep it clean. Give a key only to people who need one regularly, and know who they are. If a dog walker, a cleaner or a contractor needs access for a season, a lockbox with a code you can change afterwards is simpler than a key you have to ask for back. Tag spares with a colour or a number rather than the address. When a key does leave your control, a lost ring, a departing tenant, a relationship that has ended, that is the trigger to rekey again, and the next visit is simpler because the doors are already on one system.

What affects the quote

Mismatched keyways needing a cylinder swap
Where one door's cylinder cannot take the key the other doors share, a compatible replacement cylinder is fitted and pinned to match, and that hardware appears as its own line in the quote.
- 2
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.

Access to each door being rekeyed
A rekeying visit goes smoothly when every door is reachable without delay: an empty unit, a cleared hallway, or someone available to let the locksmith into each room. Locked common areas, tenants who are out, or furniture blocking a cylinder all add time the locksmith accounts for on site.
Same fees day, night or weekend.
Lock Rekeying: questions
How often should locks be rekeyed?
There is no calendar for it. What matters is who holds a key, not how many years have passed. Think about it when occupancy changes hands, when someone who had a key no longer needs one, or when a ring goes missing along with something that shows where you live. Between those moments a well-kept cylinder may need no scheduled care, and when it does, use whatever that cylinder's maker specifies. With the doors already on one recorded system, any repeat is a short piece of work.
Can I keep one door on a different key from the rest?
Yes, and it is common. A basement suite or in-law apartment often gets its own key so the tenant's key opens their door and nothing else, while your key opens the main house. A home office, a storage room or a shed can be kept separate for the same reason. The locksmith sets up the groups you want, pins each accordingly and tags the keys so the separate one is not mixed into the household set.
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 the census means at the door
38%
Homes of every age. About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.
In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.
37%
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
Where housing is mostly apartments and condos, mailbox locks are a regular call. A worn or lost mailbox key is a small job that a locksmith handles alongside the suite door, and the new lock comes with fresh keys cut on the spot.
