Deadbolt Installation in Nassau
The bolt on the front door is keyed on both sides. Getting out at night means finding the key in the dark, and with a toddler in the house you have decided the inside should turn by hand.
Deadbolt Installation
In plain words
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.
How the visit goesThe 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. Some mornings the key has to be jiggled before it will come back out.

How the visit goes
Glass, sidelights and what is within reach
Glass changes the conversation about which deadbolt to fit. A pane in the door or a sidelight within an arm's reach of the lock means an inside thumb-turn could be reached by breaking the glass, which is why double-cylinder deadbolts are sometimes suggested. The locksmith measures the distance from the glass to the lock, notes whether it is tempered, laminated or plain, and lays out the options: a captive thumb-turn that needs a key only when you choose, a laminated pane or a tested security film that can delay an arm, or moving the bolt height. The aim is a door that keeps a stranger out and still lets everyone inside leave with one turn of the hand.
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.
The rest of the door, tidied
A deadbolt installation usually leaves the whole entry better than it found it. Hinge screws that were loose have been replaced with longer ones that bite into the framing, so the door hangs square. Weatherstrip that pinched the door has been trimmed and the latch below the new bolt has been checked against its own strike. The bore edges are clean, any shavings and steel filings have been vacuumed from the sill and the core, and the finish around the new hardware is unmarked. Open and close the door a few times over the next week and let the locksmith know if anything changes as the door settles.

What affects the quote
Same fees day, night or weekend
1Travel 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.
2Number of doors
One front door is the simplest case. Front, back, side and garage-to-house doors done in one visit share the travel and setup, so the per-door figure usually eases as the count rises.
3Strike and frame reinforcement
A reinforced strike with long screws is standard; a full-length jamb reinforcer, a strike box or repairs to a split jamb after a forced entry are extra items quoted on their own.
Deadbolt Installation: questions
Can a deadbolt be added to a door that only has a knob?
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.
What do lock grades mean when I am picking a deadbolt?
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.
Can a keypad or smart deadbolt be fitted instead of a keyed one?
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.
