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
Interior doors are as much a part of this work as the entry. Bedroom, bathroom and closet doors in an older home usually carry a lighter mortise latch with a privacy turn button, and after decades without lubrication they stop catching or the turn button seizes. These small cases are short jobs on the bench: a clean, a spring, a new turn button spindle where the old one has sheared. Sets of interior locks are often serviced in one visit, and a bit key can be cut that operates all of them, which is how they were originally supplied when the house was built.
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
Repair, replacement cylinder or replacement case
The last step of the check is deciding what the lock needs, in plain terms, before any of it is done. Most cases need cleaning, springs and adjustment, and that is the recommendation. A cylinder lock with a worn plug may be better served by a new mortise cylinder of the same thread and cam, keeping the case. A cracked case, a bolt worn thin or a hub broken through calls for a replacement case in the same pocket, and the locksmith measures for it on the spot. You hear which of these applies and why, and if the answer is a replacement case, the choice between a reproduction and a modern case is yours to make.
Reassembly and setting the trim
The case slides home and is screwed off, then the cylinder or keyhole escutcheon goes on, followed by the spindle, knobs and rosettes. The spindle is trimmed to length so the knobs sit against the door without pinching, and the set screws are tightened so there is no free play before the latch moves. The thumb-turn is aligned with the deadbolt tail so it throws with a light touch. Paint is cleared from the faceplate and strike edges where it was catching. Then the door is closed and the whole lock is worked from both faces with the key, the knobs and the turn, several times, listening for the latch to seat.
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
1Making the inside key-free
Fitting a thumb-turn or interior release to a deadbolt that was keyed on both sides is its own small item, and one most owners of an entry door choose to include.
2Bit 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.
3Strike and hinge work
Where the door has dropped or swelled, adjusting or moving the strike and tightening or packing hinges is part of the fix. It is small work but it is listed, so you see what was done to the door.
Vintage Mortise Lock Service: questions
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.
How should I look after the lock once it is serviced?
A drop of the right lock oil into the latch and bolt once a year is plenty. If the lock has a pin-tumbler cylinder, use whatever lubricant that cylinder's maker specifies, since some take a dry graphite or PTFE product and others a specified liquid one. Try the latch and deadbolt each spring and fall; if the bolt starts to scrape, the strike wants a small adjustment before anything is strained. Keep bit keys out of a pocket where they bend.
Can my interior doors be serviced too, and can one key work all of them?
Usually yes to the first, and to the second once the locksmith checks the locks. Interior mortise latches with privacy turn buttons are lighter versions of the entry lock and respond to the same clean and re-spring. Interior locks in a house were sometimes supplied to one bit key, and where the key sections, warding and levers actually match, the locksmith can restore that arrangement so a single key opens several bedroom and bathroom doors. It is a practical thing to have when a child locks a bathroom from inside.
