Lock replacement and upgrade is the service that takes tired or under-built door hardware off and puts hardware suited to the door in its place. It ranges from a like-for-like deadbolt on a back door to a complete refit of every entrance with heavier-grade locks, reinforced strikes and one key for the house. The locksmith first confirms that the person ordering the work has the right to change the lock, then examines the door, measures the existing preparation and recommends hardware that fits it cleanly. The visit ends with each lock tested from both sides, keys in your hand and the packaging and instructions left with you.

Lock Replacement & Upgrade · Toronto

Scene 1
Each door has a job, and the hardware should match it. The main entrance needs a keyed deadbolt with an interior thumb-turn so anyone inside can leave without hunting for a key. A door with glass beside it is better served by a reinforced strike and glass protection than by a keyed cylinder on the inside. Interior doors may want passage, privacy or a keyed function, and a lever suits hands that find a knob awkward. Sorting function out first keeps looks from overriding how the door has to work.
Scene 2
Removal is done with the same care as fitting. Interior trim screws come out first, then the interior rose or thumb-turn, and the exterior housing lifts away with its tailpiece. The latch or bolt slides out of the edge bore once its two faceplate screws are released, and the old strike comes off the jamb. Painted-over screws are scored free rather than forced, seized screws are eased with a hand driver of the right size, and a stripped head is drilled out only as a last step. The bore and edge mortise are then cleaned of paint build-up and debris so the new parts seat properly.
Scene 3
Where the strike was reinforced, the improvement is mostly invisible and worth understanding. Long screws now tie the strike through the jamb into the framing, the pocket has been cut to take the whole bolt, and any split wood has been repaired. Together these make the frame the equal of the deadbolt, which is the part most break-ins defeat. The locksmith points out what changed so you can check it yourself: a bolt that seats fully with the door closed and a strike that stays put under a firm push. A twice-yearly look at those screws keeps it that way.
What shapes the quoteLeaside Lock Experts
FeesSame any hour
Yes, provided the cylinders share a compatible keyway, which the locksmith checks when choosing hardware. New cylinders are pinned on site to a single new key and any existing locks worth keeping are repinned to match. Front, back, side and garage doors commonly end up on one key, and a shed or gate padlock can join them. You then decide how many copies exist and who holds each.
The push is a sign the bolt and the strike pocket are out of line, which is a door and frame matter more than a lock fault. A new deadbolt is welcome if the old one is worn, but the visit also adjusts the strike, deepens the pocket or tightens hinges so the bolt throws freely with the door simply closed. Done together, the door locks with a fingertip and the new hardware works as designed.
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.
