- 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.

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.
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.

Lock Replacement & Upgrade · East Colborne

Scene 1
One failing lock is often the loudest of several, so the locksmith takes a short tour. The back door, the garage man-door, a basement walkout, a sliding patio door and a storm door all count, and so does the door from the garage into the house, which is often the lightest lock on the property. Each is noted for grade, condition and whether it has a deadbolt at all. You are not obliged to do them all at once; the value of the tour is a clear list ranked by what matters most, so the first replacement goes where it makes the largest difference.
Scene 2
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.
Scene 3
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.

FeesSame any hour
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.
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.
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.
