Deadbolt Installation in Freeman

You bought a keypad deadbolt online and pulled the old one off, only to find the hole in the door is a different size and the bolt latch sits at a backset the new kit does not list. The door is now open and the box is on the counter.

In plain words

Replacing an existing deadbolt is usually a matter of matching rather than cutting. The locksmith measures the cross bore, the edge bore and the backset, checks the door thickness, and picks a bolt that drops into the holes you already have. Where the old lock was a builder-grade unit, the replacement can step up to a heavier grade with a hardened bolt, a free-turning collar around the cylinder and a low-profile face that gives a wrench nothing to grip. The old strike is checked against the new bolt's instructions, and where it calls for it, a reinforced strike and long screws go in while the door is already apart.

Sound familiar?

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. It is not fine for a laneway.

  1. 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. 2

    Assembling the cylinder and thumb-turn

    The outside housing goes on first, with its tailpiece threaded through the slot in the bolt cam and its mounting posts through the matching holes. Any plastic alignment bracket that ships with the lock is used on a 54 mm bore and removed on a smaller one. The inside thumb-turn plate is set against the door and the two long tapered screws are driven through it into the outside housing, snug rather than crushed, so the housings pull tight to the door without distorting the mechanism. The locksmith turns the thumb-turn before the door is closed to confirm the bolt throws its full length and returns without a catch.

  3. 3

    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

  1. 1

    Storm 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.

  2. 2

    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.

  3. 3

    Non-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.

Same fees day, night or weekend.

Deadbolt Installation: questions

Advice · (289) 816-4986

Should I choose a single-cylinder or a double-cylinder deadbolt?

For any door people leave the house through, a single cylinder with an inside thumb-turn is the sensible choice, and provincial building rules for dwellings call for exit doors that open from inside without a key. Double-cylinder bolts are keyed on both faces and are sometimes proposed where glass is near the lock, but a captive thumb-turn, laminated glass, or a tested security-film system with its specified attachment, addresses that without a key on the inside.

I rent. Can I have a deadbolt installed on my unit door?

You can, with a conversation first. Tenancy rules in this province expect a tenant to have the landlord's consent before changing locks and expect the landlord to hold a key, so ask in writing and share the plan. Many landlords welcome a proper bolt. The locksmith can key the new cylinder to the building's existing key where the keyway allows, and leave a note of the model and keys cut for the building manager.

How do I look after a deadbolt once it is installed?

Very little is needed. Each spring and autumn, lock the door from inside and feel whether the bolt still goes home without the door being pulled; if it hesitates, the door has moved with the season and a small strike adjustment restores it. Whatever lubricant the lock's own maker specifies keeps it smooth, often a dry PTFE or graphite type in the keyway and along the bolt, though some cylinders are meant to be serviced with oil. In winter, wipe road salt off the outside trim to protect the finish.

What the census means at the door

47%

Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.

A mix of eras means a mix of bores and backsets. Standard modern sizes on one door, older dimensions on the door across the street. Carrying adapter plates and cylinders in both ranges lets a locksmith fit upgrades cleanly to either.

50%

A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).

Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
