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.

A replacement lock has to fit holes that already exist, and that is where the visit begins. The locksmith measures the backset, the distance from the door edge to the centre of the bore, which on most doors is 60 or 70 millimetres, checks the cross-bore diameter and edge-bore size, notes door thickness and handing, and looks at the strike cut-out. Most residential hardware is made to these standard preparations, so the new lock usually drops into place with no new drilling. Where a mortise lock or a thick door departs from the norm, filler plates, extension kits or a careful new bore bring the door up to standard.
How the visit goesThe keys the seller handed over came in a sandwich bag: six unlabelled copies for two locks of different makes from different decades. You have no idea how many more copies exist or who is holding them.

How the visit goes

- 1
Exposure, weather and finish
The locksmith looks at where the door lives. A side entrance beside a salted driveway, a south-facing front door in full sun and a sheltered porch each treat a finish differently, and the residential hardware label scores finish durability as its own category for exactly this reason. Existing hardware is examined for pitting, peeling and green bloom, which shows how hard the spot is on metal. That guides the choice between a PVD brass, a satin nickel, a powder-coated black or a stainless product, and whether a storm door or a small hood would help. Matching the rest of the entrance comes last, once the finish will survive the location.

Fitting the latch or bolt to the door
Most modern latches and bolts adjust between the two common backsets, so the unit is set to the measured figure and slid into the edge bore. A spring latch goes in with its bevel facing the strike, while a deadbolt is oriented the way its markings or instructions call for, not by that bevel rule. The faceplate should sit flush in its mortise; where the old cut-out differs in shape or size, the mortise is trimmed with a sharp chisel, or a round drive-in collar is used where the door was prepared that way. The bolt is checked to travel freely before anything else goes on, since a bolt that binds in the door will bind under the key too.

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
Special-order hardware
Most standard locks come from the van. A specific style, an unusual finish or a restricted system may need ordering, which affects scheduling and is noted in the quote rather than discovered on the day.
- 2
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.
- 3
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.
Same fees day, night or weekend.
Lock Replacement & Upgrade: questions
Can I stop people copying my house key?
A restricted keyway helps with that. The key blanks are controlled by the manufacturer and its authorised locksmiths, so a copy generally requires the card, record or authorisation the program uses, cutting down on copies made at an ordinary kiosk. It suits homes where keys are lent to cleaners, contractors or tenants. The cylinders are fitted in the normal way, and you keep the key card safe because it is what future copies depend on.
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.
Can a lever replace a knob on the same door?
Yes, and it is a common change for anyone who finds a knob hard to grip. Levers use the same bore and backset as knobs, so the swap is usually a direct fit. Levers are handed, so the locksmith checks which way the door swings and chooses or adjusts the lever accordingly. A keyed entry lever pairs well with a deadbolt above it, and interior passage and privacy levers complete the set.

What the census means at the door
42%
Homes of every age. About 42% of homes in Uxbridge were built in 1980 or earlier, according to the 2021 Census.
In an area where homes span several eras, one street may have original mortise locks and the next builder-grade cylinders. A locksmith working here carries parts for both, so whichever door he meets, the job finishes in one visit.
81%
Mostly houses. Single-detached houses make up about 81% of homes in Uxbridge (2021 Census).
In areas of single houses, the door nobody watches is the side or back entry. It often has the weakest lock on the property. Fitting a proper deadbolt and a reinforced strike there is a modest job that closes the obvious gap.
