Deadbolt Installation
You moved in three weeks ago. The previous owner left a handful of keys, none labelled, and the bolt on the side door rattles in its housing.

The right deadbolt for a door depends on how the door is used and where it sits. A front door that a family goes through twenty times a day needs a durable mechanism and a finish that shrugs off salt spray and sun; a side door in a laneway wants a heavy bolt and a strike that reaches the framing. Residential deadbolts carry letter grades for security, durability and finish, and heavier commercial-pattern bolts carry numbered grades, so there is a plain way to compare. The locksmith talks through those options, then fits the one you choose with the same care whichever grade it is.
How the visit goesThe bolt on the front door is keyed on both sides. Getting out at night means finding the key in the dark, and with a toddler in the house you have decided the inside should turn by hand. You want it done properly, not just swapped.
Deadbolt Installation · Richmond Hill
How the visit goes

- 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.

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.

Grade and type of deadbolt

Deadbolt Installation: questions
Can a keypad or smart deadbolt be fitted instead of a keyed one?
Yes, and the preparation is the same. Many electronic deadbolts use the standard 54 mm bore and the same edge bore, so a door cut for a mechanical bolt often accepts one, and a keyed bolt fitted today can usually be swapped for a keypad later, subject to that model's own bore, backset and thickness needs. The locksmith checks door thickness against the model, fits a reinforced strike as usual, sets up codes with you and shows where the backup cylinder or battery terminals are.
What do backset and bore mean, and why does the locksmith ask?
Two measurements decide whether a deadbolt fits your door. Bore is the diameter of the big hole through the face, 54 mm on most current hardware. Backset is how far the centre of that hole sits from the door's edge, 60 mm or 70 mm on nearly all residential doors. A replacement must match both to use the existing holes, and a fresh installation is cut to match the knob below, so knowing them ahead puts the right hardware on the van.
I 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.

What the census means at the door
15%
Newer homes. About 15% of homes in Richmond Hill were built in 1980 or earlier, according to the 2021 Census.
Households in newer homes are often keen on keypads, fobs and phone-controlled locks. Standard doors make installation straightforward, and the locksmith spends more of the visit setting codes and pairing devices than on carpentry.
57%
A mix of homes. Single-detached houses make up about 57% of homes in Richmond Hill (2021 Census).
In an area with both houses and attached homes, the work varies by the door. A detached house wants all its exterior doors on one key; a suite door wants a cylinder that suits a metal frame and respects building rules. A locksmith carries parts for both.
