Seized & Jammed Lock Opening in Country Hills
The key slides all the way in, exactly as it has for years, and then refuses to turn in either direction. Yesterday it needed a small wiggle.
Seized & Jammed Lock Opening
In plain words
A jammed lock looks like one problem from outside and is usually one of three inside. The cylinder itself may have seized, packed with grit, corrosion or old grease. The link between cylinder and bolt, the tailpiece or cam, may have broken, which is why a key can spin without doing anything. Or the lock may be healthy and the bolt simply pinned against the strike by a door that has moved. Seized and jammed lock opening starts by telling those apart, because the right answer for one would damage the hardware in another. Once the culprit is known, the door is opened and the cause is repaired.
How the visit goesThe 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.

How the visit goes
Levers, thumb-turns and mortise cases
Lever handles and mortise locks add parts that a plain deadbolt does not have, and each can jam on its own. A lever that drops without retracting the latch can have a tired return spring or a worn hub inside the case, though latch engagement, linkage, or the spindle can produce the same symptom. A thumb-turn that will not move can be a bent spindle, a stripped drive or a bolt pinned by the frame. On older houses and commercial doors the mortise case itself may be packed with decades of dust and dried grease. The locksmith works the lever, key and thumb-turn separately and feels where resistance starts, which locates the fault before the case is opened.
Taking the load off a bound bolt
When the door is the cause, the opening is a matter of leverage rather than tools. The locksmith lifts, pushes or pulls the door to bring the bolt back into line with its pocket while the key turns, and the bolt slides home. With the door open, the reason is dealt with: hinge screws tightened or replaced with longer ones that reach the framing, a hinge shimmed to raise a dropped door, the strike plate moved or its edge dressed with a file, the bolt pocket deepened with a sharp chisel, or a weatherstrip trimmed. The lock is then thrown and retracted with the door closed until it moves without any pressure on the door.
The early warnings to act on
A lock gives notice before it seizes, and now you know the signs. A key that needs a jiggle to seat, a plug that turns stiffly on cold mornings, a bolt that drags in its pocket, a lever that returns slowly, or a key that comes out gritty are all invitations to act while the fix is small. Stop as soon as a key begins to bend; a snapped key turns a service call into an extraction. A puff of dry lubricant or a turn of the strike screws often settles it, and a call while the lock still turns is a shorter visit than a call after it stops.

What affects the quote
Same fees day, night or weekend
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.
2Matching finish and keyway
A replacement that has to match an unusual finish or a restricted keyway takes a specific part rather than a stock one, and the quote reflects the part.
3Mortise 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.
Seized & Jammed Lock Opening: questions
Will I need a whole new lock?
Usually not. Most jammed locks are saved by cleaning the cylinder, fitting a small part such as a tailpiece or spring, or adjusting the door so the bolt has room. A new cylinder is fitted when the plug or shell is corroded through or twisted by forcing, matched to your finish and, where possible, pinned to your current key. A complete new lockset is usually a choice you make rather than a requirement, though some internal failures cannot be serviced in place and call for a full replacement.
How long does a jammed lock opening take?
It depends on which family the jam belongs to. A bolt bound by the door is often freed in minutes and the adjustment afterwards takes a little longer. A seized cylinder needs patient cleaning before it turns and a bench service after, and a frozen one needs thawing time. A tailpiece swap is short once the door is open; a mortise case service is longer. The locksmith gives a sense of the time once the cause is identified at the door.
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.
