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.

If your door already has a knob or lever bore and nothing above it, adding a deadbolt is a boring job in the literal sense. A jig clamps to the door at the right height, usually 140 to 150 mm above the knob centre, and guides a hole saw through the face and a smaller bit through the edge. The locksmith mortises the edge so the bolt faceplate sits flush, sets the bolt to the door's backset, then fits the cylinder outside and the thumb-turn inside. The frame is marked from the bolt itself, bored and chiselled for the strike, and the lock is tested open and closed.
How the visit goesThe 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.

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.

Testing open, then closed, then keyed alike
The finished lock is proved in three stages. With the door open, the thumb-turn and then the key are cycled several times to confirm the bolt throws fully and returns freely. With the door closed, the same tests show whether the bolt clears the strike opening and seats in the pocket; any drag is marked with chalk and the strike is dressed or shifted until the bolt moves with fingertip effort. If the cylinder is being keyed to the household key, it is repinned on the bench and tested from outside with the door closed, and every key that should work is tried before the tools go back in the van.

Looking after it through the seasons
A deadbolt asks for very little, and most of it happens twice a year. In spring and again in autumn, throw the bolt with the door closed and notice whether it still slides in freely; wood doors swell in humid summers and shrink in dry winter air, and the first sign is a bolt that needs the door pulled before it will lock. If so, a small strike adjustment puts it right. Give the bolt and keyway a puff of whatever lubricant the lock's own maker specifies, often dry PTFE or graphite, since some cylinders are serviced with oil instead. Wipe salt off the outside trim after a slushy week so the finish stays bright.

What affects the quote
- 1
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.
- 2
Door material
Solid wood, steel-clad and fibreglass doors are each cut differently. Metal skins call for slower cutting and cleanup of filings, so the material is one of the first things a quote takes into account.

Mechanical, keypad or smart lock
Electronic deadbolts carry a different hardware line and add setup time for codes, pairing to a phone and a walk-through, all of which appear as their own entries.

Deadbolt Installation: questions
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.
Someone forced my door. Can the new deadbolt go into the same frame?
In most cases, yes. The locksmith examines the jamb for splits and stripped screw holes, glues and pins any cracked section, and fits a full-length jamb reinforcer under the strike so the new long screws bite into sound wood and the stud behind. A new pocket is bored to the correct depth. Where the jamb is beyond repair, replacing that section of frame is discussed before any lock goes on.
Will drilling a new deadbolt damage my steel or fibreglass door?
Not when it is done for that door. Steel-clad doors are cut with a fine-toothed hole saw run slowly through the skin, guided by a jig so the saw cannot skate on the smooth face, and finished from both sides so each skin stays clean. Fibreglass is scored first so the surface does not chip. Shavings are vacuumed from the foam core, and the edge is finished with a collar or plate suited to the stile inside.

What the census means at the door
25%
Newer homes. About 25% of homes in Whitby were built in 1980 or earlier, according to the 2021 Census.
Recent builds often have steel or fibreglass entry doors rather than solid wood. They resist warping and take hardware well, and a locksmith fitting a deadbolt or reinforced strike works with the door's construction so screws bite into something solid.
70%
Mostly houses. Single-detached houses make up about 70% of homes in Whitby (2021 Census).
A detached house gives a locksmith room to work: full access to both sides of every door, hinges and frames included. Repairs and upgrades can be thorough, from the front deadbolt to the gate latch, with nothing off limits.
