Deadbolt Installation
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.
Deadbolt Installation
In plain words
If your door already has a knob or lever bore and nothing above it, adding a deadbolt is a boring job in the literal sense. A jig clamps to the door at the right height, usually 140 to 150 mm above the knob centre, and guides a hole saw through the face and a smaller bit through the edge. The locksmith mortises the edge so the bolt faceplate sits flush, sets the bolt to the door's backset, then fits the cylinder outside and the thumb-turn inside. The frame is marked from the bolt itself, bored and chiselled for the strike, and the lock is tested open and closed.

How the visit goes
Measuring the bore and the backset
Deadbolts are built around two dimensions. The cross bore is the large hole through the face of the door, 54 mm on most residential hardware, though some older or imported locks used 38 mm. The backset is the distance from the door edge to the centre of that hole, 60 mm or 70 mm on nearly every door in this part of the world. If a deadbolt is being replaced, both are measured so the new lock lands in the existing holes without a shim or a gap. On a new installation they are chosen to match the knob below, so the two locks line up and any future keypad or smart deadbolt drops straight in.
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.
Ready for a smart lock later
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 affects the quote
Same fees day, night or weekend
1Strike 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.
2Removing 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.
3Glass near the lock
A captive thumb-turn, laminated glass, security film or a relocated bolt height each carry their own cost, and the choice you make about glass shapes that part of the quote.
Deadbolt Installation: questions
Does a deadbolt work with a storm door or screen door?
It does, with one check: the thumb-turn and the outside cylinder have to clear the storm door when it closes. Most storm doors leave enough depth, but a low-profile deadbolt trim is chosen where the gap is tight. The storm door's own latch is separate and does not replace a bolt on the main door, since a screen frame gives little resistance on its own.
Why does the strike plate matter so much?
The strike is the metal plate the bolt throws into, and it is where a kicked door usually fails: short screws bite only into the thin jamb board, which splits. A reinforced strike or strike box fastened with 75 mm screws passes through the jamb into the stud behind, so a blow is met by the framing of the house. On a wood frame, strike screws that reach at least 30 mm into solid wood behind the jamb are what actually holds.
Does the finish of the deadbolt matter beyond looks?
It does on an exposed door. Winter salt spray, summer sun and humid air all work on the outside trim, and residential deadbolts carry a finish grade that reflects how well the coating resists them. A lifetime or PVD-style finish stays bright longer on a south-facing or roadside door, while a sheltered porch door can carry any finish you like. Matching the knob or lever below is mostly a matter of taste.
