Disclosed is a code changing structure applied to a key coded lock, the code changing structure comprising a lock seat having key slots, a push rod mounted on the lock seat, two lock plates, a knob, a linkage assembly, a reset assembly, and several sets of a key spring, a password key, a button spring and a button, with a pressing and rotating mechanism below a code changing height being provided between the button and the key slot. When all correct passwords are input, the knob can rotate, and a first angle and a second angle are set during rotation of the knob. When the knob rotates to the first angle, the key coded lock is in an unlocked state, the lock plates move away from the knob and limit the buttons to be pressed to the code changing height. When the knob rotates to the second angle, the lock plates move towards the knob to form gaps for avoidance of the buttons, and the buttons can be pressed down to the code changing height to drive the password keys to rotate to change the passwords. According to the present invention, a user can change passwords during use of a lock, and thus operation is simple and same is time-saving and labor-saving.
