Lock Replacement & Upgrade
Someone tried the back door while you were away. The jamb is splintered around the strike, the bolt is bent, and the knob turns with a grinding feel.

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.
How the visit goesEvery morning the front door key needs the same little dance: push in, lift, wiggle, turn. It has been getting worse for a year, and this week it took three tries in the cold before the deadbolt finally gave.

How the visit goes

- 1
Measuring the existing preparation
Before any product is chosen the door is measured. Backset first, the distance from the door edge to the centre of the bore, which on most doors here is 60 or 70 millimetres. Then the cross-bore diameter, the edge-bore size, the shape of the latch faceplate, the door thickness and the handing. The strike cut-out and any glass, trim or storm door that limits where hardware can sit are noted too. These few numbers decide which locks will drop straight into the door and which would need a filler plate, an extension kit or fresh drilling, so they are written down before the catalogue is opened.

Adapting older and unusual doors
Not every door is a standard modern slab. A century home with a mortise lock may keep its case and get a new cylinder and strike, or take a filler plate that lets a cylindrical deadbolt sit where the old case was, without hacking at the original stile. A door thicker than 45 millimetres gets extended spindles and screws. A sliding patio door gets a replacement mortise hook lock or a keyed surface bolt sized to the rail. Steel and fibreglass doors are drilled only with the right bits and a jig, and a new deadbolt above an existing knob is bored with a template so it sits square.

A smart lock with its backup arranged
A keypad or smart deadbolt leaves the visit with codes set for each person, auto-lock and alerts configured, and any phone pairing confirmed while the locksmith is there to check it. You are shown the low-battery signal so you recognise it, and the type of battery the maker calls for. The mechanical override key is the piece to look after: keep it on a keyring or with a neighbour rather than inside the home it opens. A second person's code is set up before the locksmith leaves, so a flat phone or a forgotten code is never a reason to stand on the porch.

What affects the quote
- 1
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.
- 2
Number of doors
One back door is a small visit; the front, back, side, garage man-door and patio slider together are a longer one, though several doors done at once share the travel and setup.
- 3
Grade of hardware
A light Grade 3 knob set, a residential deadbolt with a strong label rating and a Grade 1 commercial-style deadbolt are different products at different levels, and the quote follows the grade you choose for each door.
Same fees day, night or weekend.
Lock Replacement & Upgrade: questions
Can every door in the house work from one key?
Yes, provided the cylinders share a compatible keyway, which the locksmith checks when choosing hardware. New cylinders are pinned on site to a single new key and any existing locks worth keeping are repinned to match. Front, back, side and garage doors commonly end up on one key, and a shed or gate padlock can join them. You then decide how many copies exist and who holds each.
How long does a lock replacement take?
A straightforward like-for-like deadbolt or knob set on a standard door is often a matter of an hour or less including testing. Add time for a reinforced strike, for keying several locks alike and cutting keys, for a smart lock's setup and pairing, and for repairing a split jamb or adapting an older door. When several entrances are done together, the locksmith gives a realistic window before starting so you can plan the day.
Will a new lock fit the holes already in my door?
Usually, yes. Most residential doors are prepared to standard sizes, a 54 millimetre cross bore and a backset of 60 or 70 millimetres, and most modern hardware adjusts between those backsets. The locksmith measures before choosing, so the new lock is matched to the door rather than the other way around. Where an older mortise lock or an unusual bore is found, filler plates, extension kits or a carefully jigged new bore bring the door to standard.

What the census means at the door
23%
Newer homes. About 23% of homes in Brampton were built in 1980 or earlier, according to the 2021 Census.
In newer developments the hardware is often the same finish and style from house to house. A locksmith can offer upgrades that match what is already there, so a stronger cylinder or a new lever set fits in without looking like an afterthought.
53%
A mix of homes. Single-detached houses make up about 53% of homes in Brampton (2021 Census).
A mix of detached and attached housing means a mix of key habits: spare keys under pots at houses, fob-and-key combinations in buildings. A locksmith can improve both, with a proper key safe or keypad here and a tidy suite cylinder there.
