Deadbolt Installation in Aurora
The door from the garage into the kitchen closes on a passage knob with no lock at all.
In plain words
A deadbolt installation is also the moment to sort out keys. The new cylinder can be pinned to match the key you already use, so the household stays on one key, or set to a fresh key if you would rather retire whatever copies are in circulation. Many keypad and smart deadbolts fit the same standard bore as a mechanical one, so a door prepared today for a keyed bolt often accepts one later, though the exact model's bore and thickness still need checking. Either way you leave with keys that work in every door they are meant to, tested one by one.
How the visit goesYou bought a keypad deadbolt online and pulled the old one off, only to find the hole in the door is a different size and the bolt latch sits at a backset the new kit does not list. The door is now open and the box is on the counter.

How the visit goes
What the door is made of
The first thing the locksmith reads is the door itself, because it decides how the holes get cut. A solid wood slab in a century home bores cleanly but can split at the edge if the mortise is rushed. A steel-clad insulated door has a thin metal skin over foam, sometimes with a wood block at lock height, and needs a metal-cutting hole saw run slowly. Fibreglass behaves like a hard plastic and chips if the bit grabs. Thickness matters too: most exterior doors are 44 mm, some older ones 35 mm, and the deadbolt's screws and collar have to suit that. Ten seconds with a tape and a knuckle on the face answer all of this.
Swapping an old deadbolt in place
When an existing bolt is being replaced, the work starts by backing out the two inside screws and lifting off both housings, then removing the bolt from the edge. The bore and backset are measured against the new hardware, and any difference is dealt with before the new bolt goes in: a larger bore for a smart deadbolt, a different faceplate shape, or a spacer for a thinner door. The new bolt, cylinder and thumb-turn go on in the usual order. The old strike comes off too, the pocket is deepened if needed, and a reinforced strike with long screws replaces it, so the upgrade happens on both sides of the gap.
A bolt with a full, deadlocked throw
What you feel at the end is a bolt that travels its whole length into the frame with one turn and stops with a definite click, which is the deadlocking position that stops the bolt being pushed back from the edge. From outside, the key turns a cylinder that sits in a collar which spins if gripped. From inside, the thumb-turn moves the same bolt without a key. The locksmith shows you both, throws the bolt with the door closed so you hear it seat, and hands over the packaging with the model, finish and backset written on it for the day a matching lock is wanted on another door.

What affects the quote
Grade and type of deadbolt
A builder-grade bolt, a residential model with a high security grade, and a heavy commercial-pattern deadbolt sit at different points in the hardware part of the quote, and the locksmith explains the differences.
Travel to the property
Distance and access are part of any call-out: a house on a suburban street and a rural property down a long road involve different driving time, and the quote says so.
Door and hinge corrections
A sagging door, loose hinge screws or thick weatherstrip are put right before a bolt is fitted, and that adjustment is quoted as its own line rather than folded into the lock.
What to have ready
- Is there a storm door or screen door in the same opening?
- Does anyone in the household have trouble with small knobs or stiff thumb-turns?
- Would you like a keyed deadbolt, a keypad, or a smart lock you can control from a phone?
Deadbolt Installation: questions
QuestionsI rent. Can I have a deadbolt installed on my unit door?
You can, with a conversation first. Tenancy rules in this province expect a tenant to have the landlord's consent before changing locks and expect the landlord to hold a key, so ask in writing and share the plan. Many landlords welcome a proper bolt. The locksmith can key the new cylinder to the building's existing key where the keyway allows, and leave a note of the model and keys cut for the building manager.
How do I look after a deadbolt once it is installed?
Very little is needed. Each spring and autumn, lock the door from inside and feel whether the bolt still goes home without the door being pulled; if it hesitates, the door has moved with the season and a small strike adjustment restores it. Whatever lubricant the lock's own maker specifies keeps it smooth, often a dry PTFE or graphite type in the keyway and along the bolt, though some cylinders are meant to be serviced with oil. In winter, wipe road salt off the outside trim to protect the finish.
Can a deadbolt be added to a door that only has a knob?
Yes, on nearly any wood, steel-clad or fibreglass entry door. The locksmith marks a spot above the knob, clamps a jig to the door and bores a cross hole through the face and a smaller hole through the edge, then cuts a pocket and fits a strike on the frame. The main things checked first are the door's thickness, what is inside it at that height and whether glass sits close by.
