Vintage Mortise Lock Service in The Annex

The brass knob on the front door of your century home turns, but nothing happens on the other side.

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.

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. Who owns the door

    The first check has nothing to do with the lock. The locksmith confirms that the person asking for the work owns the home or lawfully lives in it, since a serviced lock and a freshly cut key are, in the end, a way into someone's house. Photo identification and something tying you to the address usually settles it in a moment. On a rental, the landlord and the tenant are expected to agree on lock changes and share keys, so the locksmith asks who should hold the new bit keys or cylinder keys and notes it. This small formality protects the household as much as anyone, and it is done before a screwdriver comes out.

  2. Putting the door edge right

    Before the case goes back, the pocket and screw holes get whatever attention the check turned up. Stripped holes are drilled out, plugged with glued hardwood dowel and re-drilled so the faceplate screws bite. A pocket that has loosened is packed with a thin hardwood shim glued to one wall so the case sits tight. A split at the edge is glued and clamped. None of this changes the door's appearance; it simply gives the rebuilt lock something solid to sit in, which matters because a case that shifts in its pocket will bind the spindle and undo the bench work in a few months.

  3. A lock that feels new and looks old

    What you get back is the door you had, with the lock working as it was designed to. The knob returns level with a snap, the latch catches when the door is pushed shut, the deadbolt throws with a light turn of the key or the thumb-turn, and the key goes in and out without a wiggle. Nothing on the face of the door has changed except that the brass has been cleaned where it was handled. The locksmith runs through each function with you from both sides before leaving, so the standard of what has been done is something you have seen, not something you have been told.

What affects the quote

  1. Number of locks in the visit

    One entry lock is the simplest case. A whole floor of interior latches, or the front and back doors together, is a longer visit, and each case is quoted on its own so the total is easy to follow.

  2. 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.

  3. Paint and seized parts

    Hardware buried under decades of paint takes time to free and clean without damage. A faceplate, strike and thumb-turn that have to be stripped back add to the visit and are noted in the quote.

What to have ready

  • Can you send a photo of the plate in the door edge and one of the keyhole?
  • What does the knob do when you turn it: return, sag, or not come back?
  • Is the trouble worse with the door closed than with it open?

Vintage Mortise Lock Service: questions

Questions
Can you make a key for a lock that has none?

Yes. A bit key is cut to the lock rather than copied from another key: the locksmith chooses a blank of the right size and files the bit until it clears the wards and lifts the levers inside your case, testing as they go. A pin-tumbler cylinder on a later lock is decoded or rekeyed and keys cut to it. Bring any loose keys that came with the house, since one may be close enough to serve as a starting pattern.

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.

What if the case is too worn to repair?

Then a replacement case goes into the existing pocket. Reproduction mortise cases are made in the common vintage sizes and backsets, and a modern mortise case with a cylinder fits many old pockets with minor trimming. The locksmith measures the case height, depth, backset and trim spacing before ordering, aiming for the new case to drop in with the original knobs and plates going back on, though a small pocket trim or fixing change is sometimes needed. Cutting the door for a different kind of lock is the last choice.
