Vintage Mortise Lock Service in Toronto
The brass knob on the front door of your century home turns, but nothing happens on the other side.
In plain words
Where the door has moved, the lock gets blamed. Solid wood doors in older houses swell in humid weather, shrink in winter and settle on their hinges, and a mortise lock that was set decades ago ends up with its latch and bolt aiming a little below the strike. Part of every vintage lock service is reading how the door hangs, tightening or packing the hinges, and moving or filing the strike so the latch catches and the bolt throws without lifting the handle. Often that alignment work, plus a clean and new springs, is the entire repair, and the customer gets back a door that closes with one hand.
How the visit goesSomeone painted the door years ago without removing the hardware. The faceplate, the strike and the little thumb-turn are all under several coats, the deadbolt scrapes when it moves, and the knob is stiff enough to leave marks on your hand.

How the visit goes
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.
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.
The interior doors in step
Where a set of interior mortise latches was serviced together, you leave with bedroom and bathroom doors that close and stay closed, privacy turns that actually lock, and, if you wanted it, a single bit key that operates every interior lock the way the builder intended. A note of which key fits which door goes into the house file. Interior cases need almost no care beyond a drop of oil every couple of years and a check that a turn button has not been painted over. A child who locks a bathroom and cannot reopen it is released from outside with the bit key, so keep it somewhere the adults can reach.

What affects the quote
Missing or mismatched trim
Sourcing a knob, escutcheon or thumb-turn to match the survivors, from salvage or reproduction stock, is quoted as parts plus the search. Reusing your own trim from another door avoids that line.
Replacement cylinder
When a pin-tumbler cylinder is past rekeying, a new mortise cylinder of the right thread and cam is fitted. A standard cylinder and a high-security one are different hardware and are quoted as such.
Whether the door has to come off its hinges
Some mortise cases can be serviced with the door hanging in place, while a tight jamb or a stubborn case sometimes means lifting the door off its hinges onto a level bench. That step is identified once the case is open and the repair needs are clear.
What to have ready
- Roughly when was the house built, and is the door original to it?
- Is the property designated as a heritage building?
- Is the deadbolt keyed from the inside as well as the outside?
Vintage Mortise Lock Service: questions
QuestionsWhich parts usually need replacing?
Springs, first and foremost: the latch spring, the hub spring that returns the knob, and the small springs on the deadbolt levers. After that, the spindle and knob set screws, a hub whose square has worn round, a worn deadbolt lever or follower, and on later locks the cylinder set screw or the cylinder itself. Bolts, cases and trim are almost always kept, cleaned and refitted rather than replaced.
Will the door look any different afterwards?
Usually not, when the original case is repaired: the same knobs, escutcheons, faceplate and strike go back on in the same positions, and the only visible change is paint or grime cleared from the edges that were catching. A replacement case is chosen to match the pocket so original trim is reused wherever spacing allows, though an occasional case needs a small pocket or fixing change, explained beforehand.
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.
