- The call
- You are inside, the deadbolt is thrown, and the thumb-turn will not budge. It moved a little last week with some effort. Now the door you walk through every day is a wall, and you need it open.

The 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.
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.

Seized & Jammed Lock Opening · Burlington

Scene 1
A small mirror and a bright light show what the keyway has collected. Salt crust, sand, metal filings, sawdust from a renovation and the gummy residue of household spray oils are all common, and each reads differently: a dry gritty feel, a sticky drag, or a plug that will not accept the key to full depth. Ice shows as frost on the cylinder face and a key that stops short. A cylinder cap that has loosened lets the plug sit crooked so the pins never line up. This look decides whether the cylinder needs a flush and dry lubricant, a thaw, a re-tightened cap, or a full strip on the bench.
Scene 2
Ice is melted, never chipped. A lock de-icer or gentle warmth on the cylinder face turns the frozen meltwater back to liquid so it can drain, and the key is then worked until the plug turns. Boiling water is kept well away, because it refreezes inside and can crack cold brass. Salt crust is flushed out with contact cleaner and the plug is dried thoroughly before any lubricant goes in, since salt and moisture sealed under lubricant keep corroding. The cylinder is then dressed with the lubricant specified for that product, applied once everything is dry. If the weatherstrip has frozen to the door, that bond is released and the seal wiped.
Scene 3
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.

In most cases, yes. A bolt held by the door is freed by relieving the pressure on the door. A cylinder clogged with grit or ice is cleaned and thawed until it turns. A failed tailpiece is bypassed and replaced. The lock stays on the door with its finish and your existing keys. A plug or shell that is worn, damaged, or eaten through by corrosion or earlier forcing is what has to be replaced, and that is explained before any work starts.
Often, and keeping the original hardware is usually worth trying first, since it fits the door and suits the house, though condition and the availability of matching parts decide whether a repair is realistic. The case comes out of the door edge, the decades of dust and hardened grease are cleaned away, a broken spring or worn hub is replaced with a matching part, and the contact surfaces get fresh grease. If a bit key or a cylinder has worn, a new key is cut or the cylinder rebuilt.
Better not, unless it is a proper dry lock lubricant. Household oils, general penetrating sprays and hinge silicone thicken inside the cylinder and attract grit, so they buy a day and cost a service later. If the lock is frozen, a lock de-icer is fine; boiling water is not, since it refreezes deeper in. The most useful thing to do while waiting is to stop turning the key, so it does not bend or snap.
