Vintage Mortise Lock Service in Jefferson
The brass knob on the front door of your century home turns, but nothing happens on the other side. The latch stays tucked in, the door swings free, and the only thing holding it shut is the deadbolt and a bit key that has worn down to a nub.

Vintage mortise lock service is the repair of the original lock in an older door rather than its removal. The lock is a rectangular steel case that lives inside a pocket in the door edge, and nearly everything that goes wrong with it, a tired spring, dried grease, a worn hub, a lost key, can be put right on the bench. The locksmith confirms you own or occupy the home, takes the case out through the door edge, rebuilds it, sorts out the keys and puts it back in the same pocket. The door keeps its knobs, escutcheons and history, and it locks as it did when new.
How the visit goesAfter 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

Reading the faceplate
Standing at the open door, the locksmith looks at the narrow brass or steel plate in the door edge. Its height, the spacing of its screws, any maker's stamp, and whether it shows one bolt or two tell a good deal about what is inside: a latch-only case for an interior door, a latch and deadbolt case for an entry, or a privacy function with a turn button. The distance from the door edge to the centre of the knob, the backset, is measured, along with the spindle size. These figures decide which springs, followers and, if it comes to that, which replacement case will fit, so they are written down before the lock is disturbed.

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.

Watching the door through the seasons
The lock is aligned to the door as it hangs today, and a solid wood door in an older home will move again. Through a humid summer it swells, through the heating season it shrinks, and each year the hinges settle a fraction. Twice a year, close the door and try the latch and bolt; if either has started to scrape or needs the door lifted, the strike wants a small adjustment or the hinge screws want snugging, which is a five-minute job. Doing that early keeps the rebuilt case from being strained, and it is the single habit that makes a vintage lock last another few decades without fuss.

What affects the quote

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.

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.

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.

Vintage Mortise Lock Service: questions
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.
Why does the deadbolt scrape or need a shove to throw?
Two causes cover most cases. Either paint has built up on the faceplate, the bolt or the strike so the bolt drags across it, or the door has dropped so the bolt is entering the strike pocket at an angle and rubbing its edge. Occasionally a bent deadbolt lever inside the case adds friction. Cleaning the paint back, adjusting the strike and checking the lever all happen as part of the service.
Can the lock be made more secure while keeping it original?
Yes, within reason. A later mortise case can take a modern high-security cylinder of the right thread and cam, chosen for its pick resistance; stopping casual key copying is a separate question, answered by fitting a restricted or patented key system alongside it. Longer screws into the strike and a properly seated deadbolt add more than most people expect. For a bit-key lock, the practical gains are a full-throw deadbolt and a good strike; if more is wanted, a separate modern deadbolt above it leaves the original lock untouched.

What the census means at the door
15%
Newer homes. About 15% of homes in Richmond Hill were built in 1980 or earlier, according to the 2021 Census.
New construction settles in its first years, and a door that closed perfectly at move-in can begin to catch as the frame finds its final position. A locksmith visiting a newer home adjusts strikes and hinges so the bolt throws freely again.
57%
A mix of homes. Single-detached houses make up about 57% of homes in Richmond Hill (2021 Census).
Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
