Deadbolt Installation
The front door has a handsome lever and a keyed knob, and that is all.
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.
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


Which key should open it
A deadbolt is also a key decision, so the locksmith asks how the household's keys are arranged now. If every door shares one key, the new cylinder can be pinned to that same key, provided the keyways match, so nobody's ring grows. If the house has just changed hands, this is the natural time to set the new bolt and the other exterior locks to a fresh key and retire whatever copies are out there. Restricted or high-security keyways, keypad models with a backup cylinder and locks that must match a rental building's system all steer the choice of hardware, and it is easier to settle this before the box is opened than after.
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.
A bolt with a full, deadlocked throw
What you feel at the end is a bolt that travels its whole length into the frame with one turn and stops with a definite click, which is the deadlocking position that stops the bolt being pushed back from the edge. From outside, the key turns a cylinder that sits in a collar which spins if gripped. From inside, the thumb-turn moves the same bolt without a key. The locksmith shows you both, throws the bolt with the door closed so you hear it seat, and hands over the packaging with the model, finish and backset written on it for the day a matching lock is wanted on another door.

What affects the quote
Finish and trim style
Coated finishes built for salt and sun, matching trim for an existing handleset, and low-profile faces cost differently from a standard brass or nickel unit, and you choose the level.
Storm door or restricted clearance
A tight storm door, a narrow lock stile or a decorative panel at bolt height can require low-profile trim or a shifted position, which is settled and quoted at the assessment.
Travel to the property
Distance and access are part of any call-out: a house on a suburban street and a rural property down a long road involve different driving time, and the quote says so.
What to have ready
- Has the door or frame ever been forced, or are any screw holes stripped?
- Is the door between the garage and the house one of the doors you want bolted?
- Is the door solid wood, steel-clad or fibreglass, and roughly how thick is it?
Deadbolt Installation: questions
QuestionsSomeone 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.
Can I supply my own deadbolt?
Yes. Bring the box, the template and the instructions, and tell the locksmith the model beforehand so the bore and backset can be checked against your door. If the kit turns out to need a larger hole or a different faceplate than the door has, the locksmith adapts the door or suggests a matching model. Hardware bought online sometimes arrives set for a different door thickness, which is a small adjustment on site.
