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.
Steel-clad and fibreglass doors, the common insulated entry doors in newer subdivisions, take a deadbolt happily as long as they are cut for it properly. The skin is thin metal or resin over a foam core, often with a wood block at lock height, so the cross bore is made with a hole saw suited to the skin, at low speed, and the edge is finished with a plate rather than a chisel mortise. Solid wood doors in older homes are cut conventionally, with care for splitting at the edge. The locksmith reads the door before drilling and picks the method that leaves a clean opening and a true-running bolt.

Scene 1
A bolt is only as good as what it throws into, so the jamb gets a hard look before anything is ordered. The locksmith checks whether the jamb is wood or steel, whether it is backed by solid framing at lock height or by a gap of shims and air, and whether earlier screws have torn out or been stripped. A jamb that flexes under a palm tells its own story. Where a strike has been fitted before, the old pocket is examined for depth and position, since a shallow or offset pocket is the usual reason an existing deadbolt feels stiff. This check decides between a plain strike, a reinforced strike with long screws, or a full-length jamb reinforcer.
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.

Residential deadbolts are graded under an industry standard in three categories, security, durability and finish, with letter grades from C through A, so a lock marked with three A grades has met the highest level in each. Heavier commercial-pattern bolts are graded 1, 2 or 3, with 1 the highest. The grades let you match hardware to a busy family door or an exposed side entrance without relying on the weight of the box.
Yes, and the preparation is the same. Many electronic deadbolts use the standard 54 mm bore and the same edge bore, so a door cut for a mechanical bolt often accepts one, and a keyed bolt fitted today can usually be swapped for a keypad later, subject to that model's own bore, backset and thickness needs. The locksmith checks door thickness against the model, fits a reinforced strike as usual, sets up codes with you and shows where the backup cylinder or battery terminals are.
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.
