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

Most of the value in a deadbolt is on the frame side, which is why a good installation spends as much time on the jamb as on the door. The bolt is only as strong as the pocket it throws into and the screws that hold the strike. Short screws in a standard strike bite only into the thin jamb board; a reinforced strike fastened with 75 mm screws passes through that board into the stud behind, so a blow against the door meets the house rather than a strip of pine. The pocket is cut deep enough for a full throw and aligned so the bolt slides home freely.

Sound familiar?

The 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

How the visit goes

  1. 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.

  2. Testing open, then closed, then keyed alike

    The finished lock is proved in three stages. With the door open, the thumb-turn and then the key are cycled several times to confirm the bolt throws fully and returns freely. With the door closed, the same tests show whether the bolt clears the strike opening and seats in the pocket; any drag is marked with chalk and the strike is dressed or shifted until the bolt moves with fingertip effort. If the cylinder is being keyed to the household key, it is repinned on the bench and tested from outside with the door closed, and every key that should work is tried before the tools go back in the van.

  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. 1Removing 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.

  2. 2Hardware 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.

  3. 3Rental 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.

Deadbolt Installation: questions

What should I have ready before the locksmith arrives?

Know which doors you want bolted, what they are made of, and whether each already has a deadbolt or only a knob. A photo of the door face and edge helps. Have any existing keys to hand, decide whether you want everything on one key, and mention glass near the lock, a storm door in the same opening, or a rental agreement. If you have already bought hardware, keep the box and template together.

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.

The door has to be pulled before the old bolt will lock. Will a new one fix that?

The new bolt will only lock as smoothly as the door and frame let it, so the locksmith deals with the cause as part of the installation. A door that has sagged on loose hinges gets longer hinge screws or a shim, thick weatherstrip is trimmed, and the strike is set from the bolt's actual position with the door closed. The pocket is bored deep enough for a full throw. Afterwards the bolt should slide with fingertip effort.
