Deadbolt Installation in Queenston
Someone tried the door last winter. The frame took it, but the strike plate is bent, one screw hole is stripped, and the bolt sits in the pocket at a slight angle.
Deadbolt Installation
In plain words
Replacing an existing deadbolt is usually a matter of matching rather than cutting. The locksmith measures the cross bore, the edge bore and the backset, checks the door thickness, and picks a bolt that drops into the holes you already have. Where the old lock was a builder-grade unit, the replacement can step up to a heavier grade with a hardened bolt, a free-turning collar around the cylinder and a low-profile face that gives a wrench nothing to grip. The old strike is checked against the new bolt's instructions, and where it calls for it, a reinforced strike and long screws go in while the door is already apart.
How the visit goesThe old deadbolt has grown lazy. You turn the thumb-turn and the bolt creeps out halfway, then needs a second push with the door pulled tight. Some mornings the key has to be jiggled before it will come back out.

How the visit goes
Where the bolt should sit on the door
On a door with no deadbolt yet, its height is not fixed by the manufacturer but by the door in front of you. The usual spot is 140 to 150 mm above the centre of the knob, which places the bolt near the strongest part of the lock stile and keeps both locks within one comfortable reach. The locksmith checks that this height misses any glass, decorative panel, hinge line or the wood block inside an insulated door, and that the frame behind that spot is solid rather than a gap between shims. If a storm door or screen door shares the opening, the bolt's thumb-turn and cylinder have to clear it as well.
Setting a strike that reaches the framing
A reinforced strike or strike box is centred over the pocket, squared to the edge of the jamb, and its outline is scored and chiselled to a depth that leaves the plate flush. Pilot holes are drilled, and the two holes nearest the door stop take 75 mm screws that pass through the jamb and the shim space into the stud behind, with shorter screws in the remaining holes. The long screws are driven by hand for the last turns so the heads seat without crushing the jamb. Where the jamb is thin or has been split by an earlier attempt, a full-length jamb reinforcer is fitted under the strike instead.
Keys that open what they should
You leave with the keys sorted, whichever way you chose. If the new cylinder was pinned to your existing key, every ring in the house still works and the new door has simply joined the set. If it was set to a fresh key, you have a small bundle of new keys, cut from the pins rather than copied from a worn original, and a clear idea of which old keys no longer matter. Count them, decide who carries one, and test each in the new bolt before the locksmith leaves. A spare kept with a trusted neighbour or in a small lockbox is worth arranging on the same afternoon.

What affects the quote
Same fees day, night or weekend
1Keying alike or a fresh key
Pinning the new cylinder to your existing key, or setting several doors to a new key, is bench work quoted per cylinder, plus the number of keys you ask to have cut.
2Finish and trim style
Coated finishes built for salt and sun, matching trim for an existing handleset, and low-profile faces cost differently from a standard brass or nickel unit, and you choose the level.
3New bore or replacement into existing holes
Boring a door that has never had a deadbolt takes more time and tooling than dropping a new bolt into holes that are already there, and the quote reflects which of the two your door needs.
Deadbolt Installation: questions
What about glass beside the door or a window in it?
Glass within reach of the lock is the one case where a plain thumb-turn deserves thought. Options include a captive thumb-turn that turns freely until you remove its small key, laminated glass or a tested security-film system with its specified frame attachment, or simply setting the bolt farther from the glass. Lock manufacturers describe sidelights as a weak point, so the locksmith measures the reach and lays out the choices rather than defaulting to a key on the inside.
Can the new deadbolt use the same key as my other doors?
Usually, yes. If the new lock shares a keyway with your existing cylinders, the locksmith repins it on the bench so your current key operates it, and nothing changes on anyone's ring. If the keyways differ, the other doors can be brought onto the new key instead. Say which key you want to keep before the hardware is chosen, because keyway is part of picking the lock.
What do lock grades mean when I am picking a deadbolt?
Residential deadbolts are graded under an industry standard in three categories, security, durability and finish, with letter grades from C through A, so a lock marked with three A grades has met the highest level in each. Heavier commercial-pattern bolts are graded 1, 2 or 3, with 1 the highest. The grades let you match hardware to a busy family door or an exposed side entrance without relying on the weight of the box.
