Seized & Jammed Lock Opening in Caledon
The 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.
Seized & Jammed Lock Opening
In plain words
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 shop's lever handle goes down as usual, but the latch inside the mortise case never pulls back. Staff are waiting on the sidewalk with their coffees, the door is locked, and the handle is simply moving air.

How the visit goes
Whose door, and which door
The first check is the person, not the lock. The locksmith confirms that whoever is asking for the opening is entitled to it, usually with photo identification that matches the address, or a lease, deed, property-management record or a manager who can vouch for you. For a business, a key holder or the person named on the lease is enough. If everything that proves it is behind the jammed door, the check is finished once you are inside and before the locksmith leaves. Then a short walk to the other entrances: a second door on the same key gives a comparison lock and sometimes a gentler way in.
When corrosion has taken the core
Occasionally the plug or shell has rusted or pitted past the point of cleaning, or an earlier forcing has twisted the plug in the shell. Then the cylinder is replaced rather than rebuilt. The locksmith matches the keyway and finish so the new part looks like the old one, and where the keyway allows, pins the new cylinder to the key already on your ring so nothing else in the house changes. If the whole lockset is tired, a replacement deadbolt or lever set goes on in the same visit, with the strike checked to suit it. The old parts are handed over so you can see exactly what failed.
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
Same fees day, night or weekend
1Upgrades 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.
2Which 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.
3Ice and salt on the day
A cylinder frozen solid or crusted with salt needs thawing, flushing and drying before it can even be diagnosed, and a winter call is quoted with that time in mind.
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.
How can I tell whether the lock or the door is the problem?
Try the key while gently pushing, pulling and lifting the door. If it frees up in one position, the bolt is being pinched by the frame and the door is the cause. If nothing changes, look at the key: does it go fully in and refuse to turn, or spin freely? The first points to the cylinder, the second to the tailpiece behind it. Tell the locksmith which you found and the right parts come in the van.
Could a jammed lock mean someone tampered with it?
Occasionally, but wear and weather are far more common. Signs that point to tampering are fresh scratches around the keyway, a plug that sits crooked, or debris such as glue or a broken tool tip inside, none of which appear from ordinary use. The locksmith looks for these during the inspection and says plainly what was found. If the cylinder has been damaged that way, it is replaced and, if you wish, the other doors are rekeyed.
