Deadbolt Installation

The back door has a deadbolt in name only: a short bolt, a thin brass strike held by two little screws, and a jamb you can flex with your palm. It was fine for a builder's showing.

Deadbolt Installation

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.

Sound familiar?

The 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

  1. Glass, sidelights and what is within reach

    Glass changes the conversation about which deadbolt to fit. A pane in the door or a sidelight within an arm's reach of the lock means an inside thumb-turn could be reached by breaking the glass, which is why double-cylinder deadbolts are sometimes suggested. The locksmith measures the distance from the glass to the lock, notes whether it is tempered, laminated or plain, and lays out the options: a captive thumb-turn that needs a key only when you choose, a laminated pane or a tested security film that can delay an arm, or moving the bolt height. The aim is a door that keeps a stranger out and still lets everyone inside leave with one turn of the hand.

  2. 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.

  3. Looking after it through the seasons

    A deadbolt asks for very little, and most of it happens twice a year. In spring and again in autumn, throw the bolt with the door closed and notice whether it still slides in freely; wood doors swell in humid summers and shrink in dry winter air, and the first sign is a bolt that needs the door pulled before it will lock. If so, a small strike adjustment puts it right. Give the bolt and keyway a puff of whatever lubricant the lock's own maker specifies, often dry PTFE or graphite, since some cylinders are serviced with oil instead. Wipe salt off the outside trim after a slushy week so the finish stays bright.

What affects the quote

Same fees day, night or weekend

  1. 1Rental and building requirements

    Matching a building's keyway, providing keys to a landlord or fitting a lock that a condominium corporation specifies can add hardware or bench work, each shown as its own item.

  2. 2Mechanical, keypad or smart lock

    Electronic deadbolts carry a different hardware line and add setup time for codes, pairing to a phone and a walk-through, all of which appear as their own entries.

  3. 3Door material

    Solid wood, steel-clad and fibreglass doors are each cut differently. Metal skins call for slower cutting and cleanup of filings, so the material is one of the first things a quote takes into account.

Deadbolt Installation: questions

What do backset and bore mean, and why does the locksmith ask?

Two measurements decide whether a deadbolt fits your door. Bore is the diameter of the big hole through the face, 54 mm on most current hardware. Backset is how far the centre of that hole sits from the door's edge, 60 mm or 70 mm on nearly all residential doors. A replacement must match both to use the existing holes, and a fresh installation is cut to match the knob below, so knowing them ahead puts the right hardware on the van.

Can I supply my own deadbolt?

Yes. Bring the box, the template and the instructions, and tell the locksmith the model beforehand so the bore and backset can be checked against your door. If the kit turns out to need a larger hole or a different faceplate than the door has, the locksmith adapts the door or suggests a matching model. Hardware bought online sometimes arrives set for a different door thickness, which is a small adjustment on site.

Can a keypad or smart deadbolt be fitted instead of a keyed one?

Yes, and the preparation is the same. Many electronic deadbolts use the standard 54 mm bore and the same edge bore, so a door cut for a mechanical bolt often accepts one, and a keyed bolt fitted today can usually be swapped for a keypad later, subject to that model's own bore, backset and thickness needs. The locksmith checks door thickness against the model, fits a reinforced strike as usual, sets up codes with you and shows where the backup cylinder or battery terminals are.
