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

Lock replacement and upgrade is the service that takes tired or under-built door hardware off and puts hardware suited to the door in its place. It ranges from a like-for-like deadbolt on a back door to a complete refit of every entrance with heavier-grade locks, reinforced strikes and one key for the house. The locksmith first confirms that the person ordering the work has the right to change the lock, then examines the door, measures the existing preparation and recommends hardware that fits it cleanly. The visit ends with each lock tested from both sides, keys in your hand and the packaging and instructions left with you.

The call
The brass handleset has gone blotchy and green where the winter salt reaches it, and the coating on the deadbolt is lifting in flakes. It still locks, but it looks tired beside the fresh paint on the door.

How the visit goes

Illustrative locksmith scene — Hamilton
  1. Scene 1

    Who is asking for the change

    The first check is about the person, not the door. An owner can change any lock on their home. A tenant who wants new hardware on the unit door needs the landlord's agreement, and a landlord who changes a lock while a tenant lives there hands over new keys. The locksmith asks which situation applies and, where paperwork helps, looks at identification, a deed, a lease or a property-management note. It takes a minute and it means the new lock goes on with everyone who has a stake in the door knowing about it, which is exactly how a lock should start its working life.

  2. Scene 2

    Keying the new locks to one key

    New cylinders arrive on random keys, so the locksmith pins them alike on site when you want one key for the house. Each cylinder is removed, the plug slid out on a follower so the springs stay put, and the bottom pins replaced to match a single new key. Existing cylinders that are staying are repinned the same way. Every key is then cut from the new combination, tried in every lock it should open, and any that drag are recut rather than handed over. The result is one key for the front, back and garage doors, and a clear count of how many exist.

  3. Scene 3

    An opening that is stronger, not just newer

    Where the strike was reinforced, the improvement is mostly invisible and worth understanding. Long screws now tie the strike through the jamb into the framing, the pocket has been cut to take the whole bolt, and any split wood has been repaired. Together these make the frame the equal of the deadbolt, which is the part most break-ins defeat. The locksmith points out what changed so you can check it yourself: a bolt that seats fully with the door closed and a strike that stays put under a firm push. A twice-yearly look at those screws keeps it that way.

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.

Keying alike and rekeying
Pinning new cylinders to one key and repinning existing locks to match is work per cylinder, so a whole house on a single key is quoted by the number of locks joining it.
Condition of the old hardware
Hardware that comes off cleanly is one thing; painted-over trim, seized or stripped screws and a cylinder that has to be drilled out add time before the new lock can go on.
Type of lock
A knob set, a lever, a deadbolt, a full handleset with deadbolt above, a patio door lock and a keypad or smart deadbolt each carry a different hardware cost and take different time to fit.

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.

  • 55 in 100 homes · older homes
  • About 55% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.
  • Single-detached houses make up about 95% of homes in Hamilton (2021 Census).Detached homes are exposed to weather on every side, so exterior locks see rain, salt and freezing air directly. Choosing hardware with a good finish and a cylinder that tolerates cold, then lubricating it properly, keeps every door turning through winter.
