A code changing structure for a key coded lock, including a lock base, a push rod, locking pieces, a knob, a linkage assembly, a position resetting assembly, and corresponding key springs, password keys, button springs and buttons. A press-rotating mechanism operable below a code changing height is provided between the buttons and key slots. When a correct password is entered, the knob rotate to a first angle or a second angle. When the knob rotates to the first angle, the key coded lock is in an unlocked state, the lock pieces move away from the knob and prevent the buttons to reach the code changing height. When the knob rotates to the second angle, the lock pieces move towards the knob and allow the buttons to be pressed down to the code changing height so as to drive the password keys to rotate to change the password.
