Seized & Jammed Lock Opening in Castle Green
The lock works, but only if you lean on the door with your hip while turning the key. After a week of humid weather the bolt is jammed against the strike plate, and without that push the key stops halfway.

The visit runs in a set order. On the phone you describe what the key does: refuses to turn, spins freely, or works only when the door is pushed. That description tells the locksmith what to bring. At the door, identification and your connection to the property are confirmed. The key, keyway, door fit and strike are examined before anything is forced. The opening uses the least disruptive method the condition allows. Then the failed part is serviced or replaced, the door is adjusted if it caused the jam, and the lock is tested open and closed with every key before the locksmith leaves.
How the visit goesThe old mortise lock on the front door of the house turns the key halfway and stops with a dull clunk. It has been getting harder for months, and the brass key is starting to show a bend.

How the visit goes

- 1
What the weather and the house have been doing
The last questions are about recent history. Has there been a thaw followed by a hard frost, or a stretch of humid days? Is this door on the shaded or windward side, or near a salted driveway? Was the door painted, re-hung, fitted with new weatherstripping or a storm door lately? Has anyone sprayed something into the keyway? Each answer changes the likely cause, and together they tell the locksmith whether this is a one-off, such as a freak freeze, or a lock that is going to keep doing this until the door or the lubrication habit is changed. The answers also shape the advice you leave with.

Stripping and rebuilding the cylinder on the bench
With access restored, a cylinder that seized gets a proper service. The locksmith removes it from the door, slides the plug out with a follower so the top pins and springs stay put, and lays out the pin stacks. Everything is cleaned, worn bottom pins and tired springs are replaced, and any burr on the plug is dressed. The plug is reassembled to the same combination so your existing keys keep working, then lubricated with the product that cylinder's maker specifies and cycled until it turns with a fingertip. If the key that jammed was worn, a fresh one is cut from the code rather than from that key.

A lock that turns with two fingers
You leave with a lock that operates the way it did when it was new: the key seats fully, the plug turns without a wiggle, the bolt throws and retracts through its whole travel, and the door closes and locks without a shoulder. The locksmith has cycled it from both sides and with every key, and has shown you where the trouble was, whether that was a gritty keyway, a broken tailpiece or a strike plate a few millimetres out. If you had a habit of lifting the door or pulling it toward you to lock it, that habit is now retired.

What affects the quote
- 1
Service or replace the cylinder
A cylinder that can be stripped, cleaned and rebuilt is quoted as labour with a few small parts; one corroded through is quoted with a replacement cylinder matched to your finish and keyway.

Cutting fresh keys
If a worn key was part of the trouble, keys cut from the code or a fresh master are counted individually, so say how many the household or staff need.

Type of lock on the door
A residential deadbolt, a knob latch, a lever set, a mortise case in an older house and a high-security cylinder each take different tools and time to open and to service.
Same fees day, night or weekend.
Seized & Jammed Lock Opening: questions
My keypad deadbolt is jammed and the motor just whirs. Is that the same service?
Yes, with one difference. On an electronic deadbolt the motor is trying to throw a bolt that is bound in the strike, and it strains or times out instead of driving it. Door alignment is a common cause, though batteries, corrosion, an overtightened mounting bolt, or a hardware fault can produce the same strain. The locksmith frees the bolt, adjusts the strike or hinges so it travels without resistance, checks the battery contacts, and confirms the auto-lock throws cleanly with the door closed.
The lever on our shop door goes down but the latch does not pull back. Is that a lock problem?
It usually points to the mortise case rather than the cylinder, and it is a common complaint on commercial doors. Inside the case a return spring, a worn hub, or another part of the latch's drive path can have failed, so the lever moves without driving the latch. The locksmith gets the door open, draws the case out of the door edge, replaces the worn part, cleans and greases the contact points and refits everything, then tests lever, key and thumb-turn together.
Why is it always the shaded side of the building that seizes?
The face of a building that never sees direct sun stays colder and damper, so ice in a keyway lasts days longer there and condensation sits in the cylinder rather than drying off. Wind-driven rain and snow tend to hit the same face. Those doors deserve a keyhole cover, a storm door where one fits, and a lubricant check before the season turns, and they are often the first lock a locksmith asks about.

What the census means at the door
27%
Newer homes. About 27% of homes in Oakville were built in 1980 or earlier, according to the 2021 Census.
In areas of recent construction, doors mostly carry builder-grade locks that were chosen for the whole development at once. They work, but a household that wants more can upgrade the cylinder or the whole set without any surprises about fit.
59%
A mix of homes. Single-detached houses make up about 59% of homes in Oakville (2021 Census).
In areas of mixed housing, landlords may own a house here and a few units there. A locksmith can put all of it under one master system so the owner carries one key while each tenant's key opens only their own door.
