Seized & Jammed Lock Opening in Ajax
It is the coldest morning of the winter and the key goes halfway into the side door and stops. There is frost on the face of the cylinder, and the door on the shaded side of the house has done this before.

When the cylinder is the part that has seized, the work is about cleaning rather than force. Keyways collect dust, salt spray, metal filings and residue from sprays never meant for locks, and over time the pins stop lifting cleanly. The locksmith flushes the plug with a contact cleaner, applies a penetrating lubricant, and works the key in small movements until the plug turns. With the door open the cylinder comes out, is stripped and cleaned, gets fresh springs or pins where worn, and is dressed with the lubricant specified for that cylinder. A plug or shell that is worn, damaged or eaten through by corrosion is what gets replaced.
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 is inside the keyway
A small mirror and a bright light show what the keyway has collected. Salt crust, sand, metal filings, sawdust from a renovation and the gummy residue of household spray oils are all common, and each reads differently: a dry gritty feel, a sticky drag, or a plug that will not accept the key to full depth. Ice shows as frost on the cylinder face and a key that stops short. A cylinder cap that has loosened lets the plug sit crooked so the pins never line up. This look decides whether the cylinder needs a flush and dry lubricant, a thaw, a re-tightened cap, or a full strip on the bench.

Freeing a seized cylinder without forcing it
A plug that will not turn is coaxed, not wrenched. The locksmith flushes the keyway with an electronic contact cleaner to lift out grit and old residue, then applies a penetrating lubricant sparingly, since too much simply carries dirt deeper. The key is worked in small movements, in and out and a few degrees each way, letting the pins settle back into their stacks. If the cylinder cap has loosened, it is snugged so the plug sits square. As the plug begins to move, tension is kept light so nothing inside is bent. Once the door is open, the cylinder is removed for proper cleaning rather than left with lubricant masking the wear.

What was done, in writing, with the old parts
You are told plainly which family the jam belonged to and what was done: cylinder cleaned and rebuilt, tailpiece replaced, strike moved, hinges shimmed, mortise spring fitted, or cylinder replaced and keyed to your existing key. Replaced parts are handed over so you can see the wear or the break for yourself. For a rental, tenants and landlords both benefit from that note, since it records that the lock was serviced rather than changed. For an owner it goes in the home file beside the keyway and key code, which makes the next key cut or the next service a shorter conversation.

What affects the quote
- 1
Which part is jammed
A bolt pinned by the door, a cylinder clogged with grit and a broken tailpiece are three different jobs with three different amounts of work, and the quote follows the diagnosis rather than the symptom.

Upgrades you choose on the spot
A keyhole cover, a storm door latch, a reinforced strike or a new deadbolt are optional extras some people add while the locksmith is there, each shown as its own line.

Keying a new cylinder to your existing key
Pinning a replacement cylinder to the key already on your ring, or rekeying other doors to match a new key, is extra work per cylinder and simplest to do in the same visit.

Seized & Jammed Lock Opening: questions
Is a key stuck in the lock the same problem as a jammed lock?
They are close relatives. A key that will not come out is usually a plug that has not returned to its neutral position with the shell, a cylinder cap that has loosened, debris in the keyway, or a cylinder that is pinned incorrectly; some cylinders are also designed to hold the key until the plug is returned. The locksmith frees the key first, without pulling, then treats the cause the same way as any seized cylinder.
Why did my lock seize when it worked yesterday?
Locks rarely fail in a day; they fail slowly over months and announce it in a morning. Grit and old lubricant build up in the pin stacks until one cold night thickens them past the point the key can overcome, or a door that has been drifting on its hinges finally pins the bolt after a humid week. The wiggle you needed last month was the warning. A lock in this state is usually cleaned or adjusted back to health rather than replaced.
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
23%
Newer homes. About 23% of homes in Ajax were built in 1980 or earlier, according to the 2021 Census.
New homes frequently come with strikes held by short screws into soft framing. Replacing them with longer screws that reach the stud is inexpensive work that adds real strength, and it is one of the first things a locksmith checks in a newer area.
65%
Mostly houses. Single-detached houses make up about 65% of homes in Ajax (2021 Census).
Families in houses hand keys to children, cleaners, dog walkers and neighbours. A locksmith can set up a keypad on the side door for the household and keep the front door on a conventional key, so access matches how the family actually comes and goes.
