The tumbler is the part that the key goes into. It is made to turn only when the correct key is used.
Just for the heck of it, try running a hair dryer on it to see if something has frozen. They even make a product just for frozen tumblers.
Try that and let me know if it helps. If not, then we need to think about replacing the tumbler.
