Sound familiar?Erin Mills
- 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 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.
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.

How the visit goes
Scene 1
The door before the lock
Before blaming a lock that may be perfectly sound, the locksmith looks at the door. With it open, the lock is cycled; with it closed, the latch and deadbolt are tried again. A lock that works open and fights when shut is telling you the door has moved. The gap around the door is checked top to bottom, the hinges are watched for a sag when the door is lifted, and the strike plate is inspected for bright wear marks where the bolt has been scraping past. In an older home with a solid wood door this is a routine finding, and correcting it is often most of the repair.
Scene 2
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.
Scene 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 shapes the quoteErindale Lock Experts
- 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.
- 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.
- 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.

Let's clear a few things up
What information helps before you come out?
Whether the door takes a skeleton-style bit key or a flat key in a round cylinder, roughly when the house was built, what the knob and bolt are doing, and whether the trouble is worse with the door closed. A photo of the faceplate in the door edge and one of the keyhole side is worth a great deal. Mention how many doors are involved and how many keys you would like afterwards.
The lock works with the door open but not when it is closed. Is the lock broken?
Almost certainly not. That pattern means the door has moved in its frame so the latch and bolt no longer meet the strike squarely. Solid wood doors in older houses swell in humid weather and settle on their hinges over the years. The service adjusts or shims the strike and tightens or packs the hinges so the bolt throws without lifting the door, and the lock itself is usually cleaned and lubricated at the same time.
What exactly is a mortise lock?
It is a lock built as a flat rectangular case that sits inside a pocket cut into the edge of the door, rather than through a round hole bored across it. The case holds the latch, usually a deadbolt, the hub the knob spindle turns, and the springs. On the faces of the door you see the knobs, decorative plates and either a keyhole for a bit key or a round cylinder. Most doors built before the middle of the last century carry one.

2021 census: what it means at the door
Every square is one home in a hundred.
- 38 in 100 homes · mixed ages
- 37 in 100 homes · mostly attached
- About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.In an area of varied housing ages, rekeying is the one job that fits every door. Old cylinders and new ones both take fresh pins, so a household moving into either kind of home can start with keys that nobody else holds.
- Single-detached houses make up about 37% of homes in Mississauga (2021 Census).Attached housing turns over more often than detached, so rekeying between tenants or owners is a constant. Because suite doors tend to be standard, the job is usually a straightforward pin change and a fresh set of keys cut on site.
