Vintage Mortise Lock Service
The old skeleton key still fits the keyhole, but it now needs a jiggle, a lean on the door and a little luck before the bolt moves. Last week it took three tries.
Vintage Mortise Lock Service
In plain words
The trim on the door face is the other half of the lock. The knobs ride on a square spindle that passes through the hub of the case, held by small set screws, and the escutcheons cover the spindle and keyholes. Slack in a knob, a knob that pulls off in your hand, or a thumb-turn that spins without moving the bolt usually traces to a worn spindle, a stripped set screw or a hub whose square has rounded. The service replaces spindle and screws, matches a hub or lever from stock or makes one, and fits everything so there is no free play before the latch starts to move.
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.
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 clear way out
If the entry door's deadbolt was keyed from both sides, the service leaves the inside operable without a key: a thumb-turn fitted to the bolt tail, or a knob function that releases the latch from inside. This is simply good sense for a door people use to leave the home, so nobody is stuck hunting for a key inside their own house. You are shown how the inside release works and asked to try it, and everyone in the household should know it too, especially anyone who grew up with the old habit of leaving the key in the door on the inside.

What affects the quote
Same fees day, night or weekend
1Extras you choose on the day
A high-security cylinder, a lockbox for a spare bit key or a separate modern deadbolt above the original are optional additions. None is required to make the old lock work, and each is priced as its own line.
2How 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.
3Condition of the wood
Stripped screw holes, a loosened pocket or a split at the door edge need dowelling, shimming or gluing before the case can be trusted. That woodwork is quoted once the locksmith has seen the pocket empty.
Vintage Mortise Lock Service: questions
What exactly is a mortise lock?
It is a lock built as a flat rectangular case that sits inside a pocket cut into the edge of the door, rather than through a round hole bored across it. The case holds the latch, usually a deadbolt, the hub the knob spindle turns, and the springs. On the faces of the door you see the knobs, decorative plates and either a keyhole for a bit key or a round cylinder. Most doors built before the middle of the last century carry one.
The lock works with the door open but not when it is closed. Is the lock broken?
Almost certainly not. That pattern means the door has moved in its frame so the latch and bolt no longer meet the strike squarely. Solid wood doors in older houses swell in humid weather and settle on their hinges over the years. The service adjusts or shims the strike and tightens or packs the hinges so the bolt throws without lifting the door, and the lock itself is usually cleaned and lubricated at the same time.
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.
