Another possibility is that the lock has become dirty or damaged. Over time, dust can build up in the lock's cylinder, which can cause the springs and pins to seize up. In this case spray the lock with graphite or WD-40 spray to clear the pins and return them to their original positions.
If the key itself has been damaged, it could be a cause for concern. Keys can wear down over time by frequent use, which could cause the groves to wear down or even become smoother.
