- The call
- The back door has a deadbolt in name only: a short bolt, a thin brass strike held by two little screws, and a jamb you can flex with your palm. It was fine for a builder's showing. It is not fine for a laneway.
The front door has a handsome lever and a keyed knob, and that is all. Nothing above it.
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.
Deadbolt Installation · Northcrest
How the visit goes
Scene 1
Measuring the bore and the backset
Deadbolts are built around two dimensions. The cross bore is the large hole through the face of the door, 54 mm on most residential hardware, though some older or imported locks used 38 mm. The backset is the distance from the door edge to the centre of that hole, 60 mm or 70 mm on nearly every door in this part of the world. If a deadbolt is being replaced, both are measured so the new lock lands in the existing holes without a shim or a gap. On a new installation they are chosen to match the knob below, so the two locks line up and any future keypad or smart deadbolt drops straight in.
Scene 2
Cutting a pocket the bolt can fill
The strike is located from the bolt itself rather than from a measurement. The bolt tip is chalked, the door is closed and the bolt is thrown firmly against the jamb to leave a mark at the true centre. The locksmith bores the pocket there with a 25 mm bit to a depth of at least 28 mm, so a 25 mm bolt seats fully and reaches its deadlocked position instead of stopping short and feeling stiff. The pocket is checked with the bolt extended before any plate goes on, because a strike screwed over a shallow hole hides the fault until the first cold morning when the door has moved.
Scene 3
A record for the home file
You should know what is on your door in plain terms, so the visit closes with a short account: the model and grade of deadbolt fitted, its finish, the backset and bore it sits in, whether the cylinder was keyed alike or set to a new key, how many keys were cut, and what was done on the frame side. For a rental, this note is useful for the landlord or building manager, who under tenancy rules is entitled to know what lock is on the unit and to hold a key. For an owner it is one line in the house file that makes the next locksmith visit, whenever it comes, a simpler conversation.

What shapes the quoteCalamity Corners Locksmith Co.
- 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.
- Keying 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.
- Rental and building requirements
- Matching a building's keyway, providing keys to a landlord or fitting a lock that a condominium corporation specifies can add hardware or bench work, each shown as its own item.

Let's clear a few things up
I just moved in. Should the new deadbolt be keyed to a new key?
It is a good moment for it. Nobody knows how many copies of a previous owner's key exist, so pinning the new bolt, and the rest of the exterior doors, to one fresh key retires all of them at once. Lock manufacturers list a move as one of the main reasons to rekey. You come away with a known number of keys, each tested in every door it is meant to open.
Do I need a deadbolt on the door from the garage into the house?
It is worth having. The door between an attached garage and the living space is in practice often the softest way in, since a garage door left open leaves a passage knob as the only barrier. A thumb-turn deadbolt there costs a few minutes a day and closes that gap.
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.

2021 census: what it means at the door
Every square is one home in a hundred.
- 52 in 100 homes · older homes
- 49 in 100 homes · mixed housing
- About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.Decades of seasons move a frame, and an older house often has a front door that locks easily in summer and fights in winter. Setting the strike with the seasons in mind, and choosing a lubricant that stays fluid in the cold, keeps it working year round.
- Single-detached houses make up about 49% of homes in London (2021 Census).Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
