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.
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.

Scene 1
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.
Scene 2
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.
Scene 3
The brass or bronze knobs and escutcheons on an old door have earned their patina, left alone unless you ask otherwise. Paint cleaned from a faceplate or strike leaves the bare metal as found, not polished bright. If you would rather see them shine, check the finish first: unlacquered brass takes a gentle polish well, kept off the keyhole and spindle; polishing a lacquered piece can scratch through it and start tarnish underneath. Lacquered reproduction parts resist tarnishing rather than darken to match; an unlacquered reproduction is built to age and blend in over a season or two. A light wipe when dusting is all the upkeep the trim needs; wet cleaners find their way into the case.
What shapes the quoteBuchanan Lock Services
FeesSame any hour
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.
A single entry lock that needs cleaning, springs and a strike adjustment is generally done in one visit of an hour or two. Filing a bit key adds bench time, and a set of interior latches is longer simply because there are more of them. A case that needs a part fabricated, or a replacement case that has to be ordered to size, may mean a second visit; the locksmith says so at the assessment.
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.
