- The call
- The 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.

The front door has a handsome lever and a keyed knob, and that is all. Nothing above it.
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.

Deadbolt Installation · Stop 19

Scene 1
Before a new bolt goes in, the door has to close properly on its own, so the locksmith swings it a few times and watches. A door that drops on tired hinges, binds against thick weatherstrip or has to be pulled to latch will put a new deadbolt out of line the moment the season changes. Hinge screws are tested for grip, the gap around the door is read for evenness, and the existing latch is checked against its strike. Small corrections here, such as a longer hinge screw into the framing or a trimmed weatherstrip, are made first so the deadbolt can be set to a door that sits square and stays there.
Scene 2
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.
Scene 3
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.

Know which doors you want bolted, what they are made of, and whether each already has a deadbolt or only a knob. A photo of the door face and edge helps. Have any existing keys to hand, decide whether you want everything on one key, and mention glass near the lock, a storm door in the same opening, or a rental agreement. If you have already bought hardware, keep the box and template together.
The knob or lever holds the door shut with a spring latch: a bevelled tongue that snaps into the frame and can be pushed back by anything slid into the gap. A deadbolt is a solid rectangular bar driven by the key or thumb-turn alone, and when fully thrown it locks in place so it cannot be pressed back from the edge. The knob keeps the door closed; the deadbolt keeps it locked.
The new bolt will only lock as smoothly as the door and frame let it, so the locksmith deals with the cause as part of the installation. A door that has sagged on loose hinges gets longer hinge screws or a shim, thick weatherstrip is trimmed, and the strike is set from the bolt's actual position with the door closed. The pocket is bored deep enough for a full throw. Afterwards the bolt should slide with fingertip effort.
