Vintage Mortise Lock Service
Someone 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.
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.
How the visit goesThe interior bedroom doors on the second floor have the original mortise latches, and none of them close any more. The doors drift open, the small brass turn buttons do nothing, and the keyholes have been empty for as long as anyone can remember.

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.
Inside the case on the bench
With the cover screws out, the case opens like a book: the latch bolt with its spring, the hub the spindle passes through, the deadbolt with its lever or tumblers, and the springs holding each in place. The locksmith notes what is broken, worn or merely stuck, then cleans the case with solvent and a brass brush until the old grease and rust are gone; old paint on the hardware is treated as a possible lead hazard and cleared with contained, lead-safe methods rather than dry brushing. Parts are cleaned individually, burrs are dressed off the bolts, and the hub square is checked against a fresh spindle to see whether it has rounded.
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
Same fees day, night or weekend
1Replacement 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.
2Number 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.
3Bit 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.
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.
Does a rented home need the landlord involved for this work?
Repairing a lock so it works as before is ordinary maintenance, but anything that changes who can open the door, such as a rekeyed cylinder or new keys, is something a tenant and landlord are expected to agree on and share keys for. The locksmith asks up front who should receive keys and can leave a note of what was done for the property manager, so both sides know what is on the door.
Why does my knob turn without moving the latch?
Most often the square hole in the hub inside the case has rounded with age, or the spindle has worn, so the knob turns a good way before it grips. Loose knob set screws produce the same slack. Less often a latch spring has broken and the latch is simply sitting inside the door. All of these are corrected during service by replacing the spindle and screws, bushing or replacing the hub, or fitting a new spring.
