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

After a break-in or an attempt, the door tells a story, and the new hardware should answer it. Splintered wood around the strike means the jamb gave before the lock did, so the repair pairs a heavier deadbolt with a reinforced strike and 75 millimetre screws that reach the framing behind the jamb. A bent bolt or cracked housing is replaced with a graded deadbolt whose bolt has a hardened core. A knob lock that was bumped or forced is swapped for a set with better pins. The aim is a whole opening that resists force, not merely a shinier lock.

Sound familiar?Cobourg

The call
The house is fifteen years old and every exterior door still wears the light hardware the builder fitted: a short bolt, a thin strike held by two small screws, and a knob lock that never suited a street entrance.

How the visit goes

Illustrative locksmith scene — Cobourg
  1. Scene 1

    The door and frame around the lock

    A new lock inherits whatever the door and frame are doing, so both get a look. The locksmith checks whether the door has dropped on its hinges, whether weatherstrip is pushing it out of square, and whether the bolt lands squarely in the strike pocket or rubs its edge. The pocket depth matters as well: a bolt that reaches the back of a shallow pocket is not fully thrown. Hinge screws, a jamb split from an old forced entry and a strike held by short screws are all noted, because the visit will tidy them up so the new hardware works as designed.

  2. Scene 2

    Stepping up the grade of a deadbolt

    When the brief is a stronger door, the new deadbolt is chosen for what is inside it: a bolt with a full 25 millimetre throw and a hardened steel insert that spins against a saw, a housing that stands low so a wrench has nothing to grip, and a cylinder with pins that resist picking and bumping. Fitting follows the normal steps, but the locksmith confirms the bolt reaches full extension with the door closed, because a high-grade bolt seated halfway into a shallow pocket behaves like a low-grade one. The strike is upgraded alongside it so both halves of the lock share the same standard.

  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.

Restricted keyway system
Patented cylinders and controlled key blanks cost more than standard hardware and involve setting up your key records, which is quoted separately from an ordinary replacement.
Finish and style
Standard satin nickel or brass is one line; specialty finishes, matched suites across several doors and designer handlesets are others. The finish you choose for exposure and looks is priced as the maker prices it.
Strike reinforcement and jamb repair
A reinforced strike with long screws is a modest addition; repairing a jamb split from a forced entry, or fitting a strike box into a frame that has never had one, adds labour and materials.

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.
