Vintage Mortise Lock Service

The knob flops loose on its spindle and never springs back to level. When you turn it the latch pulls in, but you have to push the knob back yourself, and lately the latch has started staying inside the door instead of catching.

In plain words

Interior doors are as much a part of this work as the entry. Bedroom, bathroom and closet doors in an older home usually carry a lighter mortise latch with a privacy turn button, and after decades without lubrication they stop catching or the turn button seizes. These small cases are short jobs on the bench: a clean, a spring, a new turn button spindle where the old one has sheared. Sets of interior locks are often serviced in one visit, and a bit key can be cut that operates all of them, which is how they were originally supplied when the house was built.

The call
After a wet summer the entry door sits lower in its frame. The lock works perfectly when the door is open, but with it shut you have to lift the handle and shoulder the door to get the deadbolt to throw.

How the visit goes

  1. Scene 1

    Which keys exist and who has them

    The locksmith asks to see every key that goes with the door: the one that works, the ones that used to, and the bag of loose bit keys that came with the house. A worn original is still the most useful pattern for a new key, and a bent one explains why the lock has become temperamental. For a cylinder lock, a lost or stolen key is a reason to rekey while the case is out, and a key that only a former occupant holds is worth retiring. The count of keys wanted afterwards is settled now too, so the spares are cut while the lock is on the bench rather than on a return visit.

  2. Scene 2

    Springs, levers and followers

    Springs are the usual culprits and the easiest fix. Broken coil and flat springs are matched from stock by length, wire gauge and shape, and fitted so the latch snaps out and the knob returns to level. A worn or cracked lever is matched from a donor case where one exists; where it does not, a replacement is filed from stock to the original's profile, which is slow, careful bench work rather than magic. A rounded hub is replaced or bushed. When every part moves as it should, the case is closed and cycled by hand with the cover on until the action is smooth and even in both directions.

  3. Scene 3

    Keys that fit the lock, and a spare

    You are handed keys made to the restored lock, counted into your hand, and each one is tried in the door before the locksmith drives away. For a bit-key lock that means keys filed to your case; copying one needs the right blanks and equipment, which most hardware counters do not stock, so the locksmith keeps the record needed to make more. For a cylinder lock it means keys cut to the new combination, with any old keys now useless. Keep one spare somewhere other than the door, ideally with a neighbour or in a lockbox, and treat bit keys gently: they bend in a pocket and a bent key is how most of these locks become stiff again.

What shapes the quoteAncaster Heights Locksmith Pros

How many keys you want
Bit keys are made individually by hand and cylinder keys are cut per copy, so the count you ask for is a line of its own. Decide who in the household needs one before the visit.
Making the inside key-free
Fitting a thumb-turn or interior release to a deadbolt that was keyed on both sides is its own small item, and one most owners of an entry door choose to include.
Travel and access
Distance to the property and how easy it is to work at the door, on a busy entry or a third-floor walk-up, are part of any call-out and are stated when the visit is booked.

Your questions, our answers

Can a modern cylinder be fitted to my old mortise lock?

Often, on cases that already take a threaded cylinder. Mortise cylinders are made in standard thread sizes and lengths with different cam shapes, and a new one is selected to match the case and the door thickness. That gives you keys cut on a machine and the option of keying the door alike with the rest of the house. A bit-key case has no cylinder to swap; its keys are made on the bench instead.

How long does servicing a mortise lock take?

A single entry lock that needs cleaning, springs and a strike adjustment is generally done in one visit of an hour or two. Filing a bit key adds bench time, and a set of interior latches is longer simply because there are more of them. A case that needs a part fabricated, or a replacement case that has to be ordered to size, may mean a second visit; the locksmith says so at the assessment.

My home is a designated heritage property. Does that change anything?

It reinforces the choice to service rather than replace. Where a property carries a heritage designation, changes affecting listed features can need extra sign-off, and original door hardware is occasionally among those features. A rebuilt mortise case with its original trim is preservation rather than alteration, and the locksmith's written record of what was retained and what was replaced is useful for your file.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 61 in 100 homes · older homes
  • About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Old brass keys wear thin, and a key that has bent for years finally lets go in a cold cylinder. In older housing stock this is a regular call, so the locksmith is ready to extract the piece, check the cylinder and cut a new key from the code.
  • Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Where houses and attached homes share an area, lockouts are as varied as the doors. A porch, a hallway or a shared vestibule each calls for a slightly different approach, and a locksmith used to all three arrives ready for whichever it is.
