- 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 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.
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
The last questions are about recent history. Has there been a thaw followed by a hard frost, or a stretch of humid days? Is this door on the shaded or windward side, or near a salted driveway? Was the door painted, re-hung, fitted with new weatherstripping or a storm door lately? Has anyone sprayed something into the keyway? Each answer changes the likely cause, and together they tell the locksmith whether this is a one-off, such as a freak freeze, or a lock that is going to keep doing this until the door or the lubrication habit is changed. The answers also shape the advice you leave with.
Scene 2
The job is finished with testing rather than with the last screw. The bolt is thrown and drawn back with the door open to prove the lock itself, then with the door closed to prove the door and strike, then from the inside with the thumb-turn or lever. Every key you hold is tried, including the spare from the drawer. If the door is a main exit, the locksmith confirms it opens from inside with one motion and no key. Any hardware that was adjusted is cycled a dozen times to make sure it stays put, and the finish is wiped clean of cleaner and lubricant.
Scene 3
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.

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.
Locks rarely fail in a day; they fail slowly over months and announce it in a morning. Grit and old lubricant build up in the pin stacks until one cold night thickens them past the point the key can overcome, or a door that has been drifting on its hinges finally pins the bolt after a humid week. The wiggle you needed last month was the warning. A lock in this state is usually cleaned or adjusted back to health rather than replaced.
They are close relatives. A key that will not come out is usually a plug that has not returned to its neutral position with the shell, a cylinder cap that has loosened, debris in the keyway, or a cylinder that is pinned incorrectly; some cylinders are also designed to hold the key until the plug is returned. The locksmith frees the key first, without pulling, then treats the cause the same way as any seized cylinder.
