Vintage Mortise Lock Service

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.

In plain words

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.

Sound familiar?

The knob flops loose on its spindle and never springs back to level. When you turn it the latch pulls in, but you have to push the knob back yourself, and lately the latch has started staying inside the door instead of catching.

How the visit goes

  1. 1

    How the knob and key actually behave

    A short conversation with the hardware comes next. The knob is turned and released: does it return smartly, sag back, or not return at all? Is there free play before the latch moves? The key is tried in the deadbolt with the door open: does the bolt throw fully, catch part way, or ignore the key while the key turns? The thumb-turn gets the same test. Each answer points somewhere different inside the case, a latch spring, a hub spring, a worn hub square, a deadbolt lever, a cylinder cam, and the locksmith is building a short list of likely parts before the cover ever comes off.

  2. 2

    Taking the lock out without marking the door

    Removal is done in a set order so nothing is forced. The knob set screws are backed off and the knobs and spindle drawn out, then the escutcheons are lifted away, their screw positions photographed for reassembly. On a cylinder lock, the small set screw in the faceplate is released and the cylinder is unthreaded from the case. The faceplate screws come out, and the case is eased from its pocket with a gentle rock, never a pry bar, because the wood at the edge of an old door is thin. Everything that comes off is bagged and labelled, and the pocket is looked at while it is empty.

  3. 3

    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

  1. 1

    Bit 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.

  2. 2

    Keying doors alike

    Bringing several interior locks onto one bit key, or several cylinders onto one flat key, is extra bench work per lock and is simplest to arrange while all the cases are out on the same visit.

  3. 3

    How 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.

Vintage Mortise Lock Service: questions

Advice · (226) 785-2980

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.

Is it safe to keep a deadbolt that is keyed on both sides of the entry door?

It is better not to. A bolt that needs a key from inside can trap the household when a key is not to hand, and a door people leave the home through works better opening without keys or special knowledge. During service the locksmith fits a thumb-turn to the bolt tail or otherwise makes the inside release without a key, keeping the vintage lock and the clear way out.

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.

What the census means at the door

52%

Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.

Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
