Vintage Mortise Lock Service in Cameron

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.

In plain words

Vintage mortise lock service is the repair of the original lock in an older door rather than its removal. The lock is a rectangular steel case that lives inside a pocket in the door edge, and nearly everything that goes wrong with it, a tired spring, dried grease, a worn hub, a lost key, can be put right on the bench. The locksmith confirms you own or occupy the home, takes the case out through the door edge, rebuilds it, sorts out the keys and puts it back in the same pocket. The door keeps its knobs, escutcheons and history, and it locks as it did when new.

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.

  1. 1

    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.

  2. 2

    Cutting a bit key to the lock

    For a bit-key lock, keys are made to the case rather than copied from a pattern. A blank with the right bow, shank and bit size is chosen, then the bit is filed by hand to clear the wards inside the case and to lift each lever to the correct height. The key is tried, marked, filed again and tried again until it turns the bolt cleanly from both sides. A second key is made to match while the first is fresh. Where a working original exists, it is used as a guide and the new key is cut to it, and a worn original can itself be gently restored if the customer wants to keep using it.

  3. 3

    How to lubricate it, and how not to

    A serviced mortise case wants very little. Once a year, a single drop of light lock oil into the latch and the bolt from the door edge, with the faceplate screws briefly backed off if needed, keeps the levers gliding. If the lock has a pin-tumbler cylinder, that cylinder gets dry graphite or a PTFE lubricant in the keyway instead, because oil in a cylinder gathers grit and stiffens the pins. General-purpose spray lubricants belong nowhere on this hardware; they flush out the little oil that should stay and leave a film that dust settles into. The locksmith will show you where the drop goes so you are not guessing.

What affects the quote

  1. 1

    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.

  2. 2

    What is actually broken inside

    A clean and new springs is the lightest job. A worn hub, a cracked lever or a part that has to be fabricated to match the original adds bench time, and the assessment names which applies before any of it starts.

  3. 3

    Condition 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

Advice · (249) 488-0915

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.

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.

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.

What the census means at the door

56%

Older homes. About 56% of homes in Kawartha Lakes were built in 1980 or earlier, according to the 2021 Census.

Basement and side entries on older homes were often fitted long after the house was built, with whatever lock was on hand. Bringing those doors up to the standard of the front entry, and onto the same key, is a common and satisfying job.

84%

Mostly houses. Single-detached houses make up about 84% of homes in Kawartha Lakes (2021 Census).

In areas of single houses, the door nobody watches is the side or back entry. It often has the weakest lock on the property. Fitting a proper deadbolt and a reinforced strike there is a modest job that closes the obvious gap.
