Deadbolt Installation in Delrex
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
A deadbolt installation is also the moment to sort out keys. The new cylinder can be pinned to match the key you already use, so the household stays on one key, or set to a fresh key if you would rather retire whatever copies are in circulation. Many keypad and smart deadbolts fit the same standard bore as a mechanical one, so a door prepared today for a keyed bolt often accepts one later, though the exact model's bore and thickness still need checking. Either way you leave with keys that work in every door they are meant to, tested one by one.
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
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.
Setting a strike that reaches the framing
A reinforced strike or strike box is centred over the pocket, squared to the edge of the jamb, and its outline is scored and chiselled to a depth that leaves the plate flush. Pilot holes are drilled, and the two holes nearest the door stop take 75 mm screws that pass through the jamb and the shim space into the stud behind, with shorter screws in the remaining holes. The long screws are driven by hand for the last turns so the heads seat without crushing the jamb. Where the jamb is thin or has been split by an earlier attempt, a full-length jamb reinforcer is fitted under the strike instead.
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
1New bore or replacement into existing holes
Boring a door that has never had a deadbolt takes more time and tooling than dropping a new bolt into holes that are already there, and the quote reflects which of the two your door needs.
2Storm door or restricted clearance
A tight storm door, a narrow lock stile or a decorative panel at bolt height can require low-profile trim or a shifted position, which is settled and quoted at the assessment.
3Keying alike or a fresh key
Pinning the new cylinder to your existing key, or setting several doors to a new key, is bench work quoted per cylinder, plus the number of keys you ask to have cut.
Deadbolt Installation: questions
How high above the knob does the deadbolt go?
The usual position is 140 to 150 mm above the centre of the knob, which lines the two locks up and keeps both within one reach. Manufacturers' templates assume that spacing, which helps a later keypad or handleset line up, though many handlesets still need their own lower hole drilled to that model's template. The height is nudged if it would land on glass, a decorative panel or a hollow spot inside an insulated door, and to make sure the frame behind it is solid.
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.
Do I need a deadbolt on the door from the garage into the house?
It is worth having. The door between an attached garage and the living space is in practice often the softest way in, since a garage door left open leaves a passage knob as the only barrier. A thumb-turn deadbolt there costs a few minutes a day and closes that gap.
