Deadbolt Installation

The 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.

In plain words

For a main exit door the hardware choice has a safety side as well as a security side. A door people leave a home through should open from the inside without a key, so a single-cylinder deadbolt with an inside thumb-turn is the standard fit rather than a bolt keyed on both faces. Where glass sits close to the lock, the answer is a captive thumb-turn, laminated glass, or a tested security-film system with its specified frame attachment, not a key on the inside. The locksmith explains the trade-offs, fits the lock that keeps a stranger out and the family able to leave, and shows everyone the thumb-turn.

The call
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. It still locks, and it still bothers you every night.

How the visit goes

  1. Scene 1

    The frame behind the strike

    A bolt is only as good as what it throws into, so the jamb gets a hard look before anything is ordered. The locksmith checks whether the jamb is wood or steel, whether it is backed by solid framing at lock height or by a gap of shims and air, and whether earlier screws have torn out or been stripped. A jamb that flexes under a palm tells its own story. Where a strike has been fitted before, the old pocket is examined for depth and position, since a shallow or offset pocket is the usual reason an existing deadbolt feels stiff. This check decides between a plain strike, a reinforced strike with long screws, or a full-length jamb reinforcer.

  2. Scene 2

    Working on a steel-clad or fibreglass door

    Insulated doors are cut with the skin in mind. A hole saw with fine teeth is run at low speed through the metal face, with the jig doing the steering so the saw does not skate on the smooth surface, and the cut is finished from the second face to keep both skins clean. Swarf is vacuumed out of the core so it cannot work into the bolt. The edge is usually a wood or composite stile inside a folded metal lip, and the bolt is finished with a drive-in collar or a plate screwed into the stile rather than a chiselled mortise. Fibreglass is scored first so the skin does not chip, then cut the same way.

  3. Scene 3

    A frame that now holds the bolt

    Behind the new strike plate is the part of the job you cannot see and will never need to think about. The pocket has been bored deep enough for the bolt to seat fully, the plate has been let into the jamb so it sits flush, and the long screws reach through the jamb into the framing behind it. On a door that had been forced or had stripped screw holes, a full-length reinforcer may sit under the strike. If you press the jamb with your palm now, it does not flex. That stiffness is what a bolt needs to do its work, and it is the reason the installation took as long on the frame as on the door.

What shapes the quoteAgincourt Locksmith Pros

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.
New 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.
Rental and building requirements

Straight answers

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.

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.

How high above the knob does the deadbolt go?

The usual position is 140 to 150 mm above the centre of the knob, which lines the two locks up and keeps both within one reach. Manufacturers' templates assume that spacing, which helps a later keypad or handleset line up, though many handlesets still need their own lower hole drilled to that model's template. The height is nudged if it would land on glass, a decorative panel or a hollow spot inside an insulated door, and to make sure the frame behind it is solid.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 58 in 100 homes · older homes
  • About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.Established homes often have non-standard bores and backsets from an earlier generation of hardware. A locksmith working in such an area carries adapter plates and cylinders in the older sizes, so an upgrade fits the existing door instead of forcing a new one.
  • Single-detached houses make up about 23% of homes in Toronto (2021 Census).Where most people live in townhouses, apartments or condos, doors come in two kinds: the suite door you control and the shared entrances the building manages. A locksmith works on your door freely and coordinates with management on the rest.
