The key turns freely in the round cylinder on the door, all the way around and back, without the bolt shifting at all. The cylinder itself wobbles slightly when you press it, as if it has come loose inside the door.
Interior doors are as much a part of this work as the entry. Bedroom, bathroom and closet doors in an older home usually carry a lighter mortise latch with a privacy turn button, and after decades without lubrication they stop catching or the turn button seizes. These small cases are short jobs on the bench: a clean, a spring, a new turn button spindle where the old one has sheared. Sets of interior locks are often serviced in one visit, and a bit key can be cut that operates all of them, which is how they were originally supplied when the house was built.

Scene 1
Before blaming a lock that may be perfectly sound, the locksmith looks at the door. With it open, the lock is cycled; with it closed, the latch and deadbolt are tried again. A lock that works open and fights when shut is telling you the door has moved. The gap around the door is checked top to bottom, the hinges are watched for a sag when the door is lifted, and the strike plate is inspected for bright wear marks where the bolt has been scraping past. In an older home with a solid wood door this is a routine finding, and correcting it is often most of the repair.
Scene 2
A pin-tumbler cylinder on a mortise lock is serviced the same way as a modern one. The plug is pushed out with a follower, the old bottom pins are replaced to a new combination, and keys are cut to match, so a lost key stops mattering. If the plug is worn past rekeying, a new mortise cylinder is selected with the same thread length, the same cam shape and a finish close to the trim, and threaded into the case to the correct depth so the cam swings the bolt without binding. The set screw is seated into the cylinder's groove, and the key is tested with the case in the door.
Scene 3
Where a set of interior mortise latches was serviced together, you leave with bedroom and bathroom doors that close and stay closed, privacy turns that actually lock, and, if you wanted it, a single bit key that operates every interior lock the way the builder intended. A note of which key fits which door goes into the house file. Interior cases need almost no care beyond a drop of oil every couple of years and a check that a turn button has not been painted over. A child who locks a bathroom and cannot reopen it is released from outside with the bit key, so keep it somewhere the adults can reach.

Almost certainly not. That pattern means the door has moved in its frame so the latch and bolt no longer meet the strike squarely. Solid wood doors in older houses swell in humid weather and settle on their hinges over the years. The service adjusts or shims the strike and tightens or packs the hinges so the bolt throws without lifting the door, and the lock itself is usually cleaned and lubricated at the same time.
Usually not, when the original case is repaired: the same knobs, escutcheons, faceplate and strike go back on in the same positions, and the only visible change is paint or grime cleared from the edges that were catching. A replacement case is chosen to match the pocket so original trim is reused wherever spacing allows, though an occasional case needs a small pocket or fixing change, explained beforehand.
Two causes cover most cases. Either paint has built up on the faceplate, the bolt or the strike so the bolt drags across it, or the door has dropped so the bolt is entering the strike pocket at an angle and rubbing its edge. Occasionally a bent deadbolt lever inside the case adds friction. Cleaning the paint back, adjusting the strike and checking the lever all happen as part of the service.
