- The call
- 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.

The key turns a full circle without any resistance and the deadbolt stays exactly where it is. There is no click, nothing moves behind the face of the lock, and the door is as closed as it was before you touched it.
Many jammed locks are not lock problems at all. Wood doors swell in humid weather and shrink in dry winter air, hinges loosen and let the door drop, and a strike plate that was fine in spring is a few millimetres out by autumn. When that happens the bolt is squeezed in its pocket and the key cannot move it. The locksmith checks this first by loading the door in different directions while working the key, and by comparing how the lock behaves with the door open. If the door is the cause, the opening is gentle and the lasting fix is a hinge, strike or seal adjustment.

Scene 1
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.
Scene 2
Occasionally the plug or shell has rusted or pitted past the point of cleaning, or an earlier forcing has twisted the plug in the shell. Then the cylinder is replaced rather than rebuilt. The locksmith matches the keyway and finish so the new part looks like the old one, and where the keyway allows, pins the new cylinder to the key already on your ring so nothing else in the house changes. If the whole lockset is tired, a replacement deadbolt or lever set goes on in the same visit, with the strike checked to suit it. The old parts are handed over so you can see exactly what failed.
Scene 3
Where a worn or drifted key was part of the jam, you now hold a key cut from the code or from a fresh master, and every spare has been tried in the lock. Retire copies that needed force, and cut future spares from the good key rather than from each other, since each generation of copying adds error. Label the keys if several locks are involved. If the cylinder was replaced and pinned to your existing key, the whole house is still on one key. Keeping a written note of the keyway and, where it exists, the key code makes any future key a simple cut.

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.
The key and cylinder are doing their job; the bar behind the cylinder that drives the bolt, called the tailpiece or cam, has broken, slipped or twisted out of engagement. It is a small part. The locksmith retracts the bolt through the mechanism or removes the cylinder to reach it, then fits a tailpiece of the right length and profile. Your cylinder and keys are unchanged afterwards.
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.
