Seized & Jammed Lock Opening in Creemore

You are inside, the deadbolt is thrown, and the thumb-turn will not budge. It moved a little last week with some effort.

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.

Sound familiar?

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.

How the visit goes

Creemore

How the visit goes

  1. Strike plate, bolt pocket and seal

    The frame side gets as much attention as the door side. The locksmith looks at where the bolt meets the strike plate: scuff marks on the plate's edge, a bolt pocket shallower than the roughly twenty-five millimetres a deadbolt needs, paint or filler that has crept into the pocket, and weatherstripping thick enough to hold the door proud of the frame. A dab of chalk on the bolt end shows exactly where it lands. These findings explain a lock that works with the door open and jams when it is shut, and they point to a chisel, a screwdriver and a strike adjustment rather than to anything inside the cylinder.

  2. 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.

  3. A door that closes without a fight

    If the door was the cause, the hinges, strike and seal have been set so the bolt has room. Keeping it that way is a seasonal habit: each spring and fall, try the lock with the door closed and no pressure on it, and snug the hinge and strike screws if the door has begun to drop. Wood keeps moving with humidity, so a door that swells in August may need a touch on the strike in September. A door that suddenly needs a push to lock is telling you early, while the fix is still a screwdriver and not a seized bolt.

What affects the quote

Same fees day, night or weekend

  1. 1Ice 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.

  2. 2Mortise and commercial hardware

    Drawing a mortise case, replacing a hub or spring and regreasing the contact points is more involved than a cylinder service, and storefront and exit hardware are quoted accordingly.

  3. 3Which 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.

Seized & Jammed Lock Opening: questions

My key is worn. Would a new copy have prevented this?

Possibly, if the key was part of the cause. A worn or bent key lifts the pins short of the shear line, so the plug binds even in a healthy cylinder, and a copy made from that key repeats the wear. A key cut from the code or from a crisp original is the fix. If the lock was also gritty or the door had moved, the new key would have eased things without settling them, which is why the locksmith checks all three.

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.

What should I tell you on the phone?

Say what the key does: refuses to turn, spins without effect, or works only when the door is pushed or pulled. Name the lock type if you can, whether it is a deadbolt, knob, lever or an old mortise lock, and which side of the building the door faces. Mention recent weather, any spray that went into the keyway, any other door you can use, and whether anyone is inside. That short list decides the tools that come.
