- The call
- The lever on the side door droops toward the floor and rattles in your hand. The latch no longer springs back on its own, so the door drifts open behind you unless you pull it shut and check it twice.
Every 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.
In plain words
Moving into a home is the classic moment for this service, because you inherit whatever hardware and whatever key copies the previous owners left behind. The locksmith walks every exterior door with you and sorts the locks into three piles: sound hardware worth keeping and rekeying, worn hardware worth replacing, and doors with no deadbolt at all. Everything that stays is pinned to one new key, new locks are keyed to match, and old copies floating around town stop mattering. You leave the visit knowing exactly which key opens which door and how many of them exist.

How the visit goes
Scene 1
Who is asking for the change
The first check is about the person, not the door. An owner can change any lock on their home. A tenant who wants new hardware on the unit door needs the landlord's agreement, and a landlord who changes a lock while a tenant lives there hands over new keys. The locksmith asks which situation applies and, where paperwork helps, looks at identification, a deed, a lease or a property-management note. It takes a minute and it means the new lock goes on with everyone who has a stake in the door knowing about it, which is exactly how a lock should start its working life.
Scene 2
Stepping up the grade of a deadbolt
When the brief is a stronger door, the new deadbolt is chosen for what is inside it: a bolt with a full 25 millimetre throw and a hardened steel insert that spins against a saw, a housing that stands low so a wrench has nothing to grip, and a cylinder with pins that resist picking and bumping. Fitting follows the normal steps, but the locksmith confirms the bolt reaches full extension with the door closed, because a high-grade bolt seated halfway into a shallow pocket behaves like a low-grade one. The strike is upgraded alongside it so both halves of the lock share the same standard.
Scene 3
Every lock tried the way you will use it
Before the tools go back in the van, each lock is operated from both sides with the door open, then closed, then closed hard against the weatherstrip. The latch should catch on its own when the door swings shut, the deadbolt should throw to its stop with a fingertip on the thumb-turn and no shoulder on the door, and the key should turn without lifting or jiggling. You are invited to try each one yourself and to lock up behind the locksmith. Anything that felt marginal has been adjusted, so the door you close that night behaves the same as the one you tested.
In the van
- Reinforced strike plate and strike box
- Adjustable latch or bolt
- Chisels, mallet and hand screwdrivers
- Knob or lever entry set
- Filler plates and thick-door extension kits
What shapes the quoteMarkland Woods Locksmith Co.
- Older and mortise hardware
- Servicing an original mortise case, sourcing a compatible cylinder or fitting a conversion plate on a century door involves more assessment and fitting time than a standard cylindrical replacement.
- Authorization needed from a property manager or landlord
- A rental or condominium unit sometimes needs sign-off from a property manager or landlord before a lock is changed, and new keys may need to reach more than one party afterward. Confirming who is authorized and who receives keys is worked out before the new hardware goes in.
- Patio and French door hardware
- Sliding door mortise locks, foot bolts and flush bolts for an inactive French door leaf are specialty items sized to the door, and they are quoted as their own line beside the entrance work.

Frequently asked questions
Can a lever replace a knob on the same door?
Yes, and it is a common change for anyone who finds a knob hard to grip. Levers use the same bore and backset as knobs, so the swap is usually a direct fit. Levers are handed, so the locksmith checks which way the door swings and chooses or adjusts the lever accordingly. A keyed entry lever pairs well with a deadbolt above it, and interior passage and privacy levers complete the set.
How long does a lock replacement take?
A straightforward like-for-like deadbolt or knob set on a standard door is often a matter of an hour or less including testing. Add time for a reinforced strike, for keying several locks alike and cutting keys, for a smart lock's setup and pairing, and for repairing a split jamb or adapting an older door. When several entrances are done together, the locksmith gives a realistic window before starting so you can plan the day.
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.

2021 census: what it means at the door
Every square is one home in a hundred.
- 38 in 100 homes · mixed ages
- 37 in 100 homes · mostly attached
- About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.Where housing is mixed, doors that have been replaced sit beside doors that never were. A new door in an old frame, or an old door in a repaired frame, needs its strike and hinges checked together so the whole assembly works as one.
- Single-detached houses make up about 37% of homes in Mississauga (2021 Census).Townhouse rows often share a keyway chosen by the builder. A locksmith can move a household onto a keyway of its own so a neighbour's key, or a key from the construction phase, no longer has any chance of fitting.
