- The call
- The 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.

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.
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 · Glenwood Beach

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
A key that spins freely means the cylinder is fine and the bar behind it, the tailpiece or cam, has broken, slipped or twisted out of engagement. The bolt is then retracted directly through the mechanism rather than through the cylinder, or the cylinder is withdrawn so the locksmith can reach the bolt drive. Once the door is open the old tailpiece is removed and a replacement of the correct length and profile is fitted, since one that is too short repeats the fault and one that is too long binds. The cylinder goes back, the retaining screws are checked, and the bolt is thrown and retracted with the key until it moves cleanly through its full travel.
Scene 3
You are told plainly which family the jam belonged to and what was done: cylinder cleaned and rebuilt, tailpiece replaced, strike moved, hinges shimmed, mortise spring fitted, or cylinder replaced and keyed to your existing key. Replaced parts are handed over so you can see the wear or the break for yourself. For a rental, tenants and landlords both benefit from that note, since it records that the lock was serviced rather than changed. For an owner it goes in the home file beside the keyway and key code, which makes the next key cut or the next service a shorter conversation.

Often, yes. A replacement cylinder in the same keyway can be pinned to the cuts on the key already on your ring, so the front and back doors stay on one key and nothing else in the house changes. If the old keyway is no longer made or the key is badly worn, the new cylinder comes with fresh keys and the other doors can be rekeyed to match in the same visit.
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.
Occasionally, but wear and weather are far more common. Signs that point to tampering are fresh scratches around the keyway, a plug that sits crooked, or debris such as glue or a broken tool tip inside, none of which appear from ordinary use. The locksmith looks for these during the inspection and says plainly what was found. If the cylinder has been damaged that way, it is replaced and, if you wish, the other doors are rekeyed.
