Lock Replacement & Upgrade

The century home's original mortise lock takes a key the size of a spoon, sticks in humid weather and has worn its strike to a groove. You want a lock that works every day without giving up the old door.

In plain words

Moving into a home is the classic moment for this service, because you inherit whatever hardware and whatever key copies the previous owners left behind. The locksmith walks every exterior door with you and sorts the locks into three piles: sound hardware worth keeping and rekeying, worn hardware worth replacing, and doors with no deadbolt at all. Everything that stays is pinned to one new key, new locks are keyed to match, and old copies floating around town stop mattering. You leave the visit knowing exactly which key opens which door and how many of them exist.

How the visit goes

Illustrative locksmith scene — Norham
  1. Scene 1

    Function, and the way out

    Each door has a job, and the hardware should match it. The main entrance needs a keyed deadbolt with an interior thumb-turn so anyone inside can leave without hunting for a key. A door with glass beside it is better served by a reinforced strike and glass protection than by a keyed cylinder on the inside. Interior doors may want passage, privacy or a keyed function, and a lever suits hands that find a knob awkward. Sorting function out first keeps looks from overriding how the door has to work.

  2. Scene 2

    Mounting the cylinder and the interior side

    The exterior housing goes on with its tailpiece passing through the slot in the bolt, oriented as the maker specifies so the keyway sits upright. The interior thumb-turn or rose is offered up and the two long mounting screws are drawn down evenly by hand until firm, not crushed; zinc housings distort and threads strip under a drill, and an over-tight rose makes a lever heavy forever. On thick doors, extension kits bring screws and spindle to length. A knob or lever set adds the latch spindle and the spring cage, and the handle is checked to return crisply to level before the trim is snugged.

  3. Scene 3

    A record of what went on the door

    You are told plainly what was fitted: the maker and model, the grade, the function and finish of each lock, whether the strike was reinforced, and how the doors are keyed. The instruction sheets and packaging stay with you, since they carry the model numbers needed for a matching lever or a spare cylinder later. The old hardware is handed over or taken away as you prefer; a sound old cylinder can be worth keeping as a spare. For a rental, this account doubles as the note a landlord or property manager will want about the new keys.

In the van

  • Knob or lever entry set
  • Adjustable latch or bolt
  • Handleset with matching deadbolt
  • Manufacturer-approved cylinder lubricant
  • Key blanks and key cutter

What shapes the quoteCobourg Lock & Key Co.

Authorization needed from a property manager or landlord
A rental or condominium unit sometimes needs sign-off from a property manager or landlord before a lock is changed, and new keys may need to reach more than one party afterward. Confirming who is authorized and who receives keys is worked out before the new hardware goes in.
Door material and thickness
Wood, steel and fibreglass doors are drilled and fitted differently, and a door thicker than the standard 45 millimetres needs extension parts, so the door itself shapes part of the quote.
Patio and French door hardware
Sliding door mortise locks, foot bolts and flush bolts for an inactive French door leaf are specialty items sized to the door, and they are quoted as their own line beside the entrance work.

Short answers to common questions

My old house has a mortise lock. Can it take modern hardware?

Often the original case can be kept and given a new cylinder and strike, which keeps the period look and the old door intact. Where the case is beyond service, a filler or conversion plate covers the mortise pocket and lets a cylindrical deadbolt or knob set be fitted without cutting into the door's stile. The locksmith looks at the door before recommending either path, since old doors vary a great deal.

What is a reinforced strike, and is it worth adding?

A standard strike is a thin plate held by two short screws in the jamb, and the jamb is what splits when a door is forced. A reinforced strike or strike box is heavier and is fixed with long screws that pass through the jamb into the framing, spreading the load into the structure. It is one of the most effective upgrades on any exterior door and is usually fitted as part of a deadbolt replacement.

What happens to the old lock?

It is yours. Some people keep a sound old cylinder as a spare or move a decent deadbolt to a shed or garage door, and the locksmith can rekey it to the house key for that purpose. Worn or damaged hardware is taken away for recycling if you prefer. Either way, the old keys should be gathered up and discarded so nobody confuses them with the new set.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 64 in 100 homes · older homes
  • About 64% of homes in Trent Hills were built in 1980 or earlier, according to the 2021 Census.Where most homes were built decades ago, doors often still carry their original mortise locks and brass knobs. That hardware can usually be cleaned, re-sprung and kept in service, with a modern deadbolt added above it for strength without losing the look.
  • Single-detached houses make up about 88% of homes in Trent Hills (2021 Census).Families in houses hand keys to children, cleaners, dog walkers and neighbours. A locksmith can set up a keypad on the side door for the household and keep the front door on a conventional key, so access matches how the family actually comes and goes.
