Vintage Mortise Lock Service
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 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 goesThe brass knob on the front door of your century home turns, but nothing happens on the other side. The latch stays tucked in, the door swings free, and the only thing holding it shut is the deadbolt and a bit key that has worn down to a nub.

How the visit goes

- 1
Bit key or cylinder
Older mortise locks come in two families, and the check sorts out which one is on the door. A keyhole shaped like a small keyhole silhouette takes a bit key, the skeleton key style, and the case works on wards and levers that the key's bit must match. A round face on the door with a slot for a flat key is a pin-tumbler cylinder threaded into the case. The distinction matters for everything that follows: how a lost key is replaced, whether the lock can be rekeyed, and what to do if the mechanism is worn out. It also settles whether a spare can be filed on the bench or cut on a key machine.

Cylinder work on a later mortise lock
A pin-tumbler cylinder on a mortise lock is serviced the same way as a modern one. The plug is pushed out with a follower, the old bottom pins are replaced to a new combination, and keys are cut to match, so a lost key stops mattering. If the plug is worn past rekeying, a new mortise cylinder is selected with the same thread length, the same cam shape and a finish close to the trim, and threaded into the case to the correct depth so the cam swings the bolt without binding. The set screw is seated into the cylinder's groove, and the key is tested with the case in the door.

Watching the door through the seasons
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.

What affects the quote
- 1
Whether the door has to come off its hinges
Some mortise cases can be serviced with the door hanging in place, while a tight jamb or a stubborn case sometimes means lifting the door off its hinges onto a level bench. That step is identified once the case is open and the repair needs are clear.

Strike 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.

Extras 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.
Same fees day, night or weekend.
Vintage Mortise Lock Service: questions
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.
Where housing is mostly older, many entries still have only a knob lock and no deadbolt at all. Adding one is a straightforward job on a solid wood door, and it is the single upgrade that changes most for a house of this kind.
84%
Mostly houses. Single-detached houses make up about 84% of homes in Kawartha Lakes (2021 Census).
Homeowners in houses often want a spare key that lives outside safely. A locksmith can fit a proper key safe or set up a keypad so a hidden key under a pot is no longer part of the plan.
