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.
Most of the value in a deadbolt is on the frame side, which is why a good installation spends as much time on the jamb as on the door. The bolt is only as strong as the pocket it throws into and the screws that hold the strike. Short screws in a standard strike bite only into the thin jamb board; a reinforced strike fastened with 75 mm screws passes through that board into the stud behind, so a blow against the door meets the house rather than a strip of pine. The pocket is cut deep enough for a full throw and aligned so the bolt slides home freely.

Scene 1
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.
Scene 2
With the height agreed, the paper template is folded over the door edge and the two centres are marked: the cross bore on the face and the edge bore on the stile. A boring jig clamps over the door so the hole saw cannot wander, and the cross bore is cut from both faces to leave clean veneer or skin on each side. The edge bore is drilled with a 25 mm bit through the stile until it meets the larger hole. The locksmith then traces the bolt faceplate on the edge and chisels a shallow mortise so the plate sits flush, keeping the cut inside the lines so the edge stays sound.
Scene 3
Because the door was prepared to the standard bore and backset, it suits many future options, though the model chosen later still sets its own bore, backset and thickness requirements. Keypad and app-controlled deadbolts fit the same 54 mm cross bore and the same edge bore as the mechanical lock fitted today, so upgrading later means swapping the hardware, not cutting the door again. The backset and bore measurements are written on the packaging left with you. If you want to think about a keypad down the road, ask the locksmith which models suit the door thickness and whether a backup keyed cylinder is worth having for the one day the batteries are flat.
What shapes the quoteBox Grove Locksmith Pros

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.
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.
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.
