In plain words

Most old mortise locks fail for boring reasons. A coil spring that has been compressed a hundred thousand times since the house was built finally breaks, or the grease inside the case dries into something like wax and the levers stick in it. Neither justifies cutting a new hole in a solid oak door. The service opens the case, cleans out the old lubricant, replaces the springs with the right size, matches any worn follower or lever and lubricates the mechanism lightly. The same case goes back into the same pocket, and the knob returns to level with the crisp snap it had decades ago.

Sound familiar?

You bought a house with its original hardware and a bag of loose keys. Some open interior doors, some fit nothing, and the front door lock has a keyhole shaped for a key you do not have. You would like the original lock kept and made to work.

How the visit goes

  1. 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. 2

    Cutting a bit key to the lock

    For a bit-key lock, keys are made to the case rather than copied from a pattern. A blank with the right bow, shank and bit size is chosen, then the bit is filed by hand to clear the wards inside the case and to lift each lever to the correct height. The key is tried, marked, filed again and tried again until it turns the bolt cleanly from both sides. A second key is made to match while the first is fresh. Where a working original exists, it is used as a guide and the new key is cut to it, and a worn original can itself be gently restored if the customer wants to keep using it.

  3. 3

    A clear way out

    If the entry door's deadbolt was keyed from both sides, the service leaves the inside operable without a key: a thumb-turn fitted to the bolt tail, or a knob function that releases the latch from inside. This is simply good sense for a door people use to leave the home, so nobody is stuck hunting for a key inside their own house. You are shown how the inside release works and asked to try it, and everyone in the household should know it too, especially anyone who grew up with the old habit of leaving the key in the door on the inside.

What affects the quote

  1. 1

    Bit key or cylinder lock

    A bit-key case has keys filed by hand on the bench, while a cylinder lock is rekeyed or fitted with a new cylinder on a key machine. The two take different time and materials, and the quote follows.

  2. 2

    Replacement case

    A case that is cracked or worn through is replaced with a reproduction or modern mortise case sized to the pocket. The case itself, any trimming of the pocket and the refitting are itemised separately from a repair.

  3. 3

    Strike and hinge work

    Where the door has dropped or swelled, adjusting or moving the strike and tightening or packing hinges is part of the fix. It is small work but it is listed, so you see what was done to the door.

Vintage Mortise Lock Service: questions

Advice · (289) 816-4986

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.

Can my interior doors be serviced too, and can one key work all of them?

Usually yes to the first, and to the second once the locksmith checks the locks. Interior mortise latches with privacy turn buttons are lighter versions of the entry lock and respond to the same clean and re-spring. Interior locks in a house were sometimes supplied to one bit key, and where the key sections, warding and levers actually match, the locksmith can restore that arrangement so a single key opens several bedroom and bathroom doors. It is a practical thing to have when a child locks a bathroom from inside.

Is it safe to keep a deadbolt that is keyed on both sides of the entry door?

It is better not to. A bolt that needs a key from inside can trap the household when a key is not to hand, and a door people leave the home through works better opening without keys or special knowledge. During service the locksmith fits a thumb-turn to the bolt tail or otherwise makes the inside release without a key, keeping the vintage lock and the clear way out.

What the census means at the door

47%

Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.

In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.

50%

A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).

Where housing is mixed, the same street can hold a solid wood front door, a steel townhouse door and a metal-clad suite door. A locksmith fits each with hardware suited to its construction, so every neighbour ends up with a door that locks properly.
