Deadbolt Installation
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
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 goesThe front door has a handsome lever and a keyed knob, and that is all. Nothing above it. When the door is shut, the only thing keeping it closed is a spring latch the width of a thumbnail, and you have started to notice.

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.
Working on a steel-clad or fibreglass door
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.
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
Same fees day, night or weekend
1Non-standard bore or backset
Older doors with a small cross bore, an unusual backset or a mortise lock case need adapting or filling before a modern deadbolt fits, and that preparation is quoted before work begins.
2Strike 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.
3Number 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.
Deadbolt Installation: questions
What is the difference between a deadbolt and the lock in my door knob?
The knob or lever holds the door shut with a spring latch: a bevelled tongue that snaps into the frame and can be pushed back by anything slid into the gap. A deadbolt is a solid rectangular bar driven by the key or thumb-turn alone, and when fully thrown it locks in place so it cannot be pressed back from the edge. The knob keeps the door closed; the deadbolt keeps it locked.
Someone forced my door. Can the new deadbolt go into the same frame?
In most cases, yes. The locksmith examines the jamb for splits and stripped screw holes, glues and pins any cracked section, and fits a full-length jamb reinforcer under the strike so the new long screws bite into sound wood and the stud behind. A new pocket is bored to the correct depth. Where the jamb is beyond repair, replacing that section of frame is discussed before any lock goes on.
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.
