Deadbolt Installation in York Mills
The front door has a handsome lever and a keyed knob, and that is all.
In plain words
For a main exit door the hardware choice has a safety side as well as a security side. A door people leave a home through should open from the inside without a key, so a single-cylinder deadbolt with an inside thumb-turn is the standard fit rather than a bolt keyed on both faces. Where glass sits close to the lock, the answer is a captive thumb-turn, laminated glass, or a tested security-film system with its specified frame attachment, not a key on the inside. The locksmith explains the trade-offs, fits the lock that keeps a stranger out and the family able to leave, and shows everyone the thumb-turn.
How the visit goesThe door from the garage into the kitchen closes on a passage knob with no lock at all. Anyone who opens the garage is one turn of a handle from the house, and the insurance renewal form has a question about exactly that.

How the visit goes
How the door hangs and closes
Before a new bolt goes in, the door has to close properly on its own, so the locksmith swings it a few times and watches. A door that drops on tired hinges, binds against thick weatherstrip or has to be pulled to latch will put a new deadbolt out of line the moment the season changes. Hinge screws are tested for grip, the gap around the door is read for evenness, and the existing latch is checked against its strike. Small corrections here, such as a longer hinge screw into the framing or a trimmed weatherstrip, are made first so the deadbolt can be set to a door that sits square and stays there.
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
Door and hinge corrections
A sagging door, loose hinge screws or thick weatherstrip are put right before a bolt is fitted, and that adjustment is quoted as its own line rather than folded into the lock.
Hardware supplied by you or by the locksmith
If you have already bought the lock, the quote covers labour and any adaptation of the door to that kit. Hardware supplied from the van is listed separately with its grade and finish.
Grade and type of deadbolt
A builder-grade bolt, a residential model with a high security grade, and a heavy commercial-pattern deadbolt sit at different points in the hardware part of the quote, and the locksmith explains the differences.
What to have ready
- Have you already bought the hardware, and if so which model and does the template come with it?
- Is the door solid wood, steel-clad or fibreglass, and roughly how thick is it?
- Is there glass in the door or a sidelight beside it within arm's reach of the lock?
Deadbolt Installation: questions
QuestionsSomeone 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.
Will drilling a new deadbolt damage my steel or fibreglass door?
Not when it is done for that door. Steel-clad doors are cut with a fine-toothed hole saw run slowly through the skin, guided by a jig so the saw cannot skate on the smooth face, and finished from both sides so each skin stays clean. Fibreglass is scored first so the surface does not chip. Shavings are vacuumed from the foam core, and the edge is finished with a collar or plate suited to the stile inside.
I just moved in. Should the new deadbolt be keyed to a new key?
It is a good moment for it. Nobody knows how many copies of a previous owner's key exist, so pinning the new bolt, and the rest of the exterior doors, to one fresh key retires all of them at once. Lock manufacturers list a move as one of the main reasons to rekey. You come away with a known number of keys, each tested in every door it is meant to open.
