Seized & Jammed Lock Opening in Donwood
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
Most seized locks can be saved, and keeping your existing hardware is the aim. A cylinder that has stopped turning is usually recoverable with cleaning and fresh internal parts. A failed tailpiece is a small component swapped without touching the rest of the lock. A bolt bound by the door needs adjustment, not new hardware. Replacement is the answer for a plug or shell that is worn, damaged or hollowed out by corrosion beyond what cleaning and parts can fix, and then the new cylinder is matched to your keyway and finish and, where possible, keyed to the key already in your pocket.
How the visit goesIt 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
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.
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.
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
1Which 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.
2Door and hinge adjustment
When the door caused the jam, hinge screws, shims, a strike move or a deepened bolt pocket are quoted as their own line beside the opening.
3Cutting 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.
Seized & Jammed Lock Opening: questions
How do I stop this from happening again?
Three habits cover most of it. Lubricate the cylinder with a dry lock product twice a year and keep oils out of it. Check that the door locks with no pressure on it each spring and fall, snugging hinge and strike screws when it starts to drag. Keep a lock de-icer handy and fit a keyhole cover on exposed doors. And act on the first stiff turn, because a lock that still turns is a smaller job than one that has stopped.
What is a tailpiece, and why does it matter here?
The tailpiece is the flat bar that sticks out of the back of a deadbolt cylinder and turns the bolt mechanism when the key turns; on a knob or lever set the equivalent part is a cam or spindle. It carries all the twisting effort, so a bent, worn or broken one is the reason a key can turn without anything happening. It is a small part to replace, it comes in several lengths, and the right length matters.
What lubricant should I use afterwards, and how often?
Whatever lubricant and interval the cylinder's manufacturer specifies, applied with a few turns of the key. Stay with that one product, because mixing different lubricants can make a paste. Oil, hinge silicone and general-purpose penetrating sprays are kept out of the keyway. Lock manufacturers describe cleaning the cylinder with an electronic contact cleaner before lubricating, and that is the order the locksmith follows on a service too.
