How do I add audio to my phone matrix buttons in my code?

I followed this page but I could not get password.h to work so I did it a different way. I however can not get my audio to play per pin. Anyone know how to write this in?

//phone test sketch eagon 10/30/19
//when lift handset off dialtone runs, when press a button dial tone stops and button presses make sounds, when put in password it sends
//signal to the relay until reset button is pressed

//achievement audio does not play after password is correct
#include <Key.h>
#include <Keypad.h>

char* secretCode = "4567";
int position = 0;

const byte rows = 4;
const byte cols = 4;
char keys[rows][cols] = {
{'1', '4', '7', '*'},
{'2', '5', '8', '0'},
{'3', '6', '9', '#'},
{'A', 'A', 'C', 'B'}
};

byte rowPins[rows] = {9, 8, 7, 6};
byte colPins[cols] = {5, 4, 3, 2};

Keypad keypad = Keypad(makeKeymap(keys),
rowPins, colPins,
rows, cols);

const int dialtone = 12 ;
const int keytone = 13 ;
int relay = 11;
const int handset = 10;

// variables will change:
int handsetState = 0; // variable for reading the pushbutton status

void setup()
{

setLocked(true);
pinMode(dialtone, OUTPUT);
pinMode(keytone, OUTPUT);
pinMode(relay, OUTPUT);
pinMode(handset, INPUT_PULLUP);

}

void loop()
{

// read the state of the pushbutton value:
handsetState = digitalRead(handset);

// check if the pushbutton is pressed. If it is, the buttonState is HIGH:
if (handsetState == LOW) {
// turn LED on:
digitalWrite(dialtone, HIGH);

} else {
// turn LED off:
digitalWrite(dialtone, LOW);
}
char key = keypad.getKey();
if (key == 'A' || key == 'B') {
position = 0;
setLocked(true);
}

if (key == secretCode[position]) {
position++;
}

if (position == 4) {
setLocked(false);
}
delay(50);
}

void setLocked(int locked)
{

if (locked) {
digitalWrite(relay, LOW);

}
else {
digitalWrite(relay, HIGH);

}

}

What audio? I don’t even see the code trying to play audio.

How are things wired up? Is it like that link? That looked rubbish.

Please post a schematic and say what your code does and what you want it to do.

I understand that there is no code to play audio, that is because that is what your asking help with. I would suggest start looking and working with the tone library, it has most of what you want to do. It will take some time to become familiar with it but it is good.
Good Luck & Have Fun!
