A key, a lock core and a lock, relating to a key, a lock core and a lock are provided. The key includes: a column body, a first end of the column body being provided with a light emitting component; a first cathode component disposed on the column body and connected to one end of the light emitting component to be mated with a second cathode component in the lock core; a first piezoelectric electrode disposed on the column body and connected to the other end of the light emitting component to be pressed against a second piezoelectric electrode in the lock core. When the first cathode component is mated with the second cathode component in the lock core, and the first piezoelectric electrode is pressed against the second piezoelectric electrode in the lock core, a piezoelectric current is generated, to cause the light emitting component to emit light.
