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.

In plain words

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.

Sound familiar?Cobourg

The call
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. Some mornings the key has to be jiggled before it will come back out.

How the visit goes

Illustrative locksmith scene
  1. Scene 1

    Glass, sidelights and what is within reach

    Glass changes the conversation about which deadbolt to fit. A pane in the door or a sidelight within an arm's reach of the lock means an inside thumb-turn could be reached by breaking the glass, which is why double-cylinder deadbolts are sometimes suggested. The locksmith measures the distance from the glass to the lock, notes whether it is tempered, laminated or plain, and lays out the options: a captive thumb-turn that needs a key only when you choose, a laminated pane or a tested security film that can delay an arm, or moving the bolt height. The aim is a door that keeps a stranger out and still lets everyone inside leave with one turn of the hand.

  2. Scene 2

    Assembling the cylinder and thumb-turn

    The outside housing goes on first, with its tailpiece threaded through the slot in the bolt cam and its mounting posts through the matching holes. Any plastic alignment bracket that ships with the lock is used on a 54 mm bore and removed on a smaller one. The inside thumb-turn plate is set against the door and the two long tapered screws are driven through it into the outside housing, snug rather than crushed, so the housings pull tight to the door without distorting the mechanism. The locksmith turns the thumb-turn before the door is closed to confirm the bolt throws its full length and returns without a catch.

  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.

In the van

  • 25 mm auger bit
  • 75 mm (3 in) strike screws
  • Sharp chisel and mallet
  • Single-cylinder deadbolt
  • Bolt faceplate or drive-in collar

What shapes the quoteCobourg Lock & Key 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.
Glass near the lock
A captive thumb-turn, laminated glass, security film or a relocated bolt height each carry their own cost, and the choice you make about glass shapes that part of the quote.
Hardware supplied by you or by the locksmith
If you have already bought the lock, the quote covers labour and any adaptation of the door to that kit. Hardware supplied from the van is listed separately with its grade and finish.

Short answers to common questions

How long does a deadbolt installation take?

A replacement into existing holes is generally the shorter visit, and boring a fresh door with a new strike takes longer, roughly an hour or two per door including the frame work and testing. Steel doors, keying alike, frame repairs after a forced entry and fitting a jamb reinforcer each add time. The locksmith can give a realistic estimate once the door and frame have been looked at.

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.

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
  • About 52% of homes in Cobourg 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 58% of homes in Cobourg (2021 Census).Neighbourhoods of houses beside townhouses and low-rise buildings have a range of door constructions: solid wood, steel, fibreglass and metal-clad. A locksmith who works in such an area is used to fitting hardware to all of them without new holes.
