Three teenagers, a dog walker, a cleaner and one house key that keeps going missing. You are tired of cutting copies and would rather give each person a code you can switch off, with a proper deadbolt behind it.

Sometimes the reason is simply that the hardware looks wrong or has weathered badly. Road salt, freeze-thaw and humid summers are hard on finishes, and a brass handleset can go blotchy while a lacquered knob peels. The locksmith helps you pick a finish that suits the exposure, whether matte black, satin nickel or a PVD brass that resists tarnish, and matches the deadbolt, handleset and interior levers so the entrance reads as one design. Function and grade are chosen alongside looks, so a door refreshed for appearance also comes out better protected.
How the visit goesEvery morning the front door key needs the same little dance: push in, lift, wiggle, turn. It has been getting worse for a year, and this week it took three tries in the cold before the deadbolt finally gave.

How the visit goes

- 1
Measuring the existing preparation
Before any product is chosen the door is measured. Backset first, the distance from the door edge to the centre of the bore, which on most doors here is 60 or 70 millimetres. Then the cross-bore diameter, the edge-bore size, the shape of the latch faceplate, the door thickness and the handing. The strike cut-out and any glass, trim or storm door that limits where hardware can sit are noted too. These few numbers decide which locks will drop straight into the door and which would need a filler plate, an extension kit or fresh drilling, so they are written down before the catalogue is opened.

Mounting the cylinder and the interior side
The exterior housing goes on with its tailpiece passing through the slot in the bolt, oriented as the maker specifies so the keyway sits upright. The interior thumb-turn or rose is offered up and the two long mounting screws are drawn down evenly by hand until firm, not crushed; zinc housings distort and threads strip under a drill, and an over-tight rose makes a lever heavy forever. On thick doors, extension kits bring screws and spindle to length. A knob or lever set adds the latch spindle and the spring cage, and the handle is checked to return crisply to level before the trim is snugged.

The rental paperwork, quietly sorted
If the door belongs to a rental unit, the visit finishes with the keys in the right hands. When a landlord orders the change, giving the tenant a full set of new keys is standard practice. When a tenant orders it with the landlord's consent, a key for the landlord is cut alongside the household's and the consent is noted. The locksmith can leave a short written record of the hardware fitted and the keys issued for the property file, so both sides know what is on the door and nobody is surprised at the next inspection or move-out.

What affects the quote
- 1
Special-order hardware
Most standard locks come from the van. A specific style, an unusual finish or a restricted system may need ordering, which affects scheduling and is noted in the quote rather than discovered on the day.
- 2
Restricted keyway system
Patented cylinders and controlled key blanks cost more than standard hardware and involve setting up your key records, which is quoted separately from an ordinary replacement.
- 3
Keys cut
Each key is counted, and restricted keys cut against a card are a different item from standard blanks. Say how many people need one and the quote lists them.
Same fees day, night or weekend.
Lock Replacement & Upgrade: questions
What information helps before the visit?
Photographs of each lock from outside and inside, plus one of the door edge showing the latch plate and one of the strike on the frame, tell the locksmith most of what they need. Add the door thickness if you can measure it, whether the door is wood, steel or fibreglass, the finish you want to match, how many doors are involved and whether you want them all on one key.
Can the same visit replace locks on more than one door, or does each door need its own appointment?
One visit usually covers every door on the job. The locksmith brings a range of cylinders and strikes, measures each door's backset and bore, and works through the list in order, front entrance first if a key change matters most there. Having a rough list ready, which doors, and whether they should end up on one key or several, lets the locksmith plan hardware before arriving rather than working it out door by door on site.
Will a new lock fit the holes already in my door?
Usually, yes. Most residential doors are prepared to standard sizes, a 54 millimetre cross bore and a backset of 60 or 70 millimetres, and most modern hardware adjusts between those backsets. The locksmith measures before choosing, so the new lock is matched to the door rather than the other way around. Where an older mortise lock or an unusual bore is found, filler plates, extension kits or a carefully jigged new bore bring the door to standard.

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.
Mixed housing ages mean the advice changes door by door. An older solid-wood entry may want a strike reinforced; a newer steel door may want its short strike screws swapped. The locksmith looks at the door in front of him rather than assuming.
37%
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
Condo boards commonly set rules about what may be changed on the outside face of a suite door. A locksmith experienced with attached housing knows to keep the visible hardware within those rules while still upgrading the cylinder and strike behind it.
