Vintage Mortise Lock Service in Firth's Corners

The old skeleton key still fits the keyhole, but it now needs a jiggle, a lean on the door and a little luck before the bolt moves. Last week it took three tries.

Vintage Mortise Lock Service

In plain words

Servicing the original lock is usually the better choice for an older home, for practical reasons as much as sentimental ones. Cutting a period door for a modern cylindrical lockset means boring a large hole through the stile and leaves the old mortise to be filled; a repaired mortise case avoids all of that. Where the home is a designated heritage property, keeping the hardware may also be what the municipality expects. The service treats the door as something to preserve: minimal disturbance, parts matched to the original, a strike adjusted rather than replaced, and the old lock left running smoothly for decades to come.

Sound familiar?

The key turns freely in the round cylinder on the door, all the way around and back, without the bolt shifting at all. The cylinder itself wobbles slightly when you press it, as if it has come loose inside the door.

How the visit goes

How the visit goes

  1. Bit key or cylinder

    Older mortise locks come in two families, and the check sorts out which one is on the door. A keyhole shaped like a small keyhole silhouette takes a bit key, the skeleton key style, and the case works on wards and levers that the key's bit must match. A round face on the door with a slot for a flat key is a pin-tumbler cylinder threaded into the case. The distinction matters for everything that follows: how a lost key is replaced, whether the lock can be rekeyed, and what to do if the mechanism is worn out. It also settles whether a spare can be filed on the bench or cut on a key machine.

  2. Taking the lock out without marking the door

    Removal is done in a set order so nothing is forced. The knob set screws are backed off and the knobs and spindle drawn out, then the escutcheons are lifted away, their screw positions photographed for reassembly. On a cylinder lock, the small set screw in the faceplate is released and the cylinder is unthreaded from the case. The faceplate screws come out, and the case is eased from its pocket with a gentle rock, never a pry bar, because the wood at the edge of an old door is thin. Everything that comes off is bagged and labelled, and the pocket is looked at while it is empty.

  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

Same fees day, night or weekend

  1. 1Making 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.

  2. 2Bit 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.

  3. 3Strike 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

What do I get at the end of the visit?

A lock you have tested yourself from both sides, keys counted into your hand with a spare, any parts that were removed if you want them, and a short written note of what was done: case type, parts replaced, keys made, strike adjusted. For a bit-key lock the locksmith keeps the details needed to cut further keys later. You also get shown where the yearly drop of oil goes.

Is it worth repairing an old mortise lock instead of replacing it?

Usually, yes. The mechanisms are simple and robust, and what fails is nearly always a spring, dried grease or wear on one part, all of which are repairable on a bench. Replacing the lock with a modern cylindrical set means boring a large hole through the door stile and filling the old pocket, which is more work and changes the door for good. A rebuilt case keeps the original trim and keeps the door intact.

Do I need to prove I own the house before you work on the lock?

Yes, and it is a normal part of any lock or key work. Photo identification together with something that ties you to the address is enough. If you rent, the locksmith will ask who should receive the keys, because landlords and tenants in this province are expected to agree on lock changes and share keys. This check takes a moment and it protects every household the locksmith is asked to work for.
