Seized & Jammed Lock Opening in Trent 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
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 goesEvery time you pull the key out of the side door it comes away gritty. The lock has been sticky since the salt trucks started running, and today it has gone from sticky to solid, with the bolt still thrown.

How the visit goes
Loading the door while the key is worked
With the lock family narrowed, the locksmith puts a hand on the door. Pushing it into the frame, pulling it out, and lifting on the handle each change how a bound bolt sits in its pocket, and the key is tried gently in each position. If the key frees up under one of those loads, the door is the cause. Where a second entrance is open, the same lock family is compared with the door swung wide, since a bolt that throws smoothly in mid-air and binds when closed has been pinched by the frame. Nothing is forced during this test; it is a diagnosis, not an attempt.
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.
Keeping the cylinder clean and dry
A serviced cylinder stays that way with very little effort. At the interval and with the product that cylinder's maker specifies, a short burst of lock lubricant into the keyway followed by a few turns of the key is enough; stay with that one product, since mixing lubricants makes a paste. Household oils, penetrating sprays and silicone meant for hinges belong nowhere near the pins, because they thicken and attract grit. Wipe the key before it goes in on a muddy or salty day. If the lock ever starts to drag, a puff of lubricant is the first response, and a call is the second.

What affects the quote
Same fees day, night or weekend
1Matching 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.
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.
3Signs of an earlier struggle
A key snapped in the plug, a twisted cylinder or a bent latch from a screwdriver adds an extraction or a repair to the opening, and the locksmith points that out before quoting it.
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.
