Deadbolt Installation
Someone 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.
Deadbolt Installation
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 goesThe 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. You want it done properly, not just swapped.

How the visit goes
Which key should open it
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.
Fitting the bolt and setting the backset
The bolt assembly slides into the edge bore with the faceplate set the way its maker marks, commonly the word "top" facing up. Most residential bolts adjust between 60 mm and 70 mm by twisting or sliding the faceplate, and the locksmith sets it to the backset measured earlier so the tailpiece from the cylinder lands in the centre of the bolt's cam. The bolt is secured with its two short screws, and the locksmith works it in and out by hand to feel that it runs freely through the door without rubbing on the bore. On an insulated door a round drive-in collar may replace the flat plate where the edge is too thin to mortise.
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
What about glass beside the door or a window in it?
Glass within reach of the lock is the one case where a plain thumb-turn deserves thought. Options include a captive thumb-turn that turns freely until you remove its small key, laminated glass or a tested security-film system with its specified frame attachment, or simply setting the bolt farther from the glass. Lock manufacturers describe sidelights as a weak point, so the locksmith measures the reach and lays out the choices rather than defaulting to a key on the inside.
Can the new deadbolt use the same key as my other doors?
Usually, yes. If the new lock shares a keyway with your existing cylinders, the locksmith repins it on the bench so your current key operates it, and nothing changes on anyone's ring. If the keyways differ, the other doors can be brought onto the new key instead. Say which key you want to keep before the hardware is chosen, because keyway is part of picking the lock.
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.
