Deadbolt Installation
The front door has a handsome lever and a keyed knob, and that is all.
In plain words
Deadbolt installation puts a solid bolt lock on a door that either has none or has one that is past its useful life. Unlike the spring latch in a knob or lever, a deadbolt is a straight bar of metal that only moves when the key or thumb-turn moves it, so a card slipped into the gap or a shove against the door does nothing. The locksmith bores the door if needed, fits the bolt and cylinder, cuts a proper pocket in the frame and secures a reinforced strike with screws long enough to reach the framing. You are left with a door that locks with a firm, full throw.
How the visit goesSomeone tried the door last winter. The frame took it, but the strike plate is bent, one screw hole is stripped, and the bolt sits in the pocket at a slight angle. It still locks, and it still bothers you every night.

How the visit goes


Where the bolt should sit on the door
On a door with no deadbolt yet, its height is not fixed by the manufacturer but by the door in front of you. The usual spot is 140 to 150 mm above the centre of the knob, which places the bolt near the strongest part of the lock stile and keeps both locks within one comfortable reach. The locksmith checks that this height misses any glass, decorative panel, hinge line or the wood block inside an insulated door, and that the frame behind that spot is solid rather than a gap between shims. If a storm door or screen door shares the opening, the bolt's thumb-turn and cylinder have to clear it as well.
Testing open, then closed, then keyed alike
The finished lock is proved in three stages. With the door open, the thumb-turn and then the key are cycled several times to confirm the bolt throws fully and returns freely. With the door closed, the same tests show whether the bolt clears the strike opening and seats in the pocket; any drag is marked with chalk and the strike is dressed or shifted until the bolt moves with fingertip effort. If the cylinder is being keyed to the household key, it is repinned on the bench and tested from outside with the door closed, and every key that should work is tried before the tools go back in the van.
Keys that open what they should
You leave with the keys sorted, whichever way you chose. If the new cylinder was pinned to your existing key, every ring in the house still works and the new door has simply joined the set. If it was set to a fresh key, you have a small bundle of new keys, cut from the pins rather than copied from a worn original, and a clear idea of which old keys no longer matter. Count them, decide who carries one, and test each in the new bolt before the locksmith leaves. A spare kept with a trusted neighbour or in a small lockbox is worth arranging on the same afternoon.

What affects the quote
Removing and disposing of the old hardware
Some visits end with the old deadbolt and strike left with the homeowner, and others ask for it to be removed and hauled away. Taking the old hardware away adds a small amount of time and is agreed before the new deadbolt goes in.
Number 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.
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
- Which doors do you want a deadbolt on, and does each one already have a bolt or only a knob?
- Would you like a keyed deadbolt, a keypad, or a smart lock you can control from a phone?
- Do you want the new deadbolt to work on the same key as your other doors?
Deadbolt Installation: questions
QuestionsWhat happens during the visit, step by step?
The locksmith looks at the door, frame, glass and hinges, measures the bore and backset, and confirms the hardware and key plan with you. The door is bored or the old lock removed, the bolt is set to the backset, and the cylinder and thumb-turn are assembled. The strike position is marked from the bolt itself, the pocket bored, and a reinforced strike fastened into the framing. Everything is tested open and closed, keys are cut and tried, and the area is vacuumed.
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.
What should I have ready before the locksmith arrives?
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.
