Lock looks something like this: https://www.hometips.com/repair-fix/door-lock-latch-problems.html
It is for bedrm in home. See 2nd picture in link. Initial problem was I couldn't turn that "thingy" at the center of the interior knob that quarter turn to lock position. I removed lock from door and eventually by messing around w/ a screwdriver, I was able to manually move things so that that "thingy" now functions so I can lock the door.
Remaining problem is that if I lock the door, I cannot unlock it. I can insert/remove the key ok but when the key is inserted, the knob/cylinder will not turn. (If the door is not locked, the knob will turn and I can open the door).
That lock is not used much. I installed it just in case we had workers in the home and wanted to lock the bedrm for some reason. Otherwise it just sits there.
Ideas for fix? Does it need something to undo a freeze(things stuck together) or just a lubricant (graphite or silicone)
