- The call
- After 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.

The key turns freely in the round cylinder on the door, all the way around and back, without the bolt shifting at all. The cylinder itself wobbles slightly when you press it, as if it has come loose inside the door.
Keys are the part of the job people expect to be impossible, and they rarely are. A bit key, the skeleton key style used on older doors, is cut and filed on the bench to the wards and levers of your particular case, so a lost key can be replaced from the lock itself. A round cylinder on a later mortise lock is rekeyed like any modern cylinder, or exchanged for a new cylinder of matching thread and cam if it is worn out. Either way the service ends with keys in your hand that turn the original lock, and a spare made while the case is on the bench.

Scene 1
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.
Scene 2
If the old case could not be saved, the replacement is fitted to the door rather than the door to the replacement. A reproduction or modern mortise case matching the measured height, depth, backset, faceplate and hub is chosen with the goal of it dropping into the existing pocket; where a small difference remains, the pocket is trimmed with a chisel by the least amount that works, never bored out. The original knobs, escutcheons and strike are refitted wherever their spacing allows, and a new cylinder is keyed to match the rest of the house if wanted. The result reads as the original lock from either side of the door, with the reliability of a fresh mechanism.
Scene 3
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.

Yes. A bit key is cut to the lock rather than copied from another key: the locksmith chooses a blank of the right size and files the bit until it clears the wards and lifts the levers inside your case, testing as they go. A pin-tumbler cylinder on a later lock is decoded or rekeyed and keys cut to it. Bring any loose keys that came with the house, since one may be close enough to serve as a starting pattern.
Then a replacement case goes into the existing pocket. Reproduction mortise cases are made in the common vintage sizes and backsets, and a modern mortise case with a cylinder fits many old pockets with minor trimming. The locksmith measures the case height, depth, backset and trim spacing before ordering, aiming for the new case to drop in with the original knobs and plates going back on, though a small pocket trim or fixing change is sometimes needed. Cutting the door for a different kind of lock is the last choice.
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.
