too few arguments to function 'void changePassword(KeypadEvent)' Error message

Hi, I am trying to change the password that allows the servo motor to rotate, but i'm getting an error message.I really need your help, because i have tried all that i could but havn't got a solution.

Here is my code

#include <Keypad.h>
#include <Servo.h>
#include <Password.h>
#include <EEPROM.h>

int addr  =0;   //the current address in the EEPROM
// Set up keypad variables:
Password password =Password("756");
const byte ROWS = 4;              //four rows
const byte COLS = 3;              //three columns

// Set up servo variables:
int angle = 0;                    // Angle in degrees to position servo [0-180]
Servo servo;                      // Create the servo object

char keys[ROWS][COLS] = {
  {'1','2','3'},
  {'4','5','6'},
  {'7','8','9'},
  {'*','0','#'}
};


// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these Arduino pins.
byte rowPins[ROWS] = {3, 8, 7, 5};

// Connect keypad COL0, COL1 and COL2 to these Arduino pins.
byte colPins[COLS] = {4, 2, 6 };

// Create the Keypad
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

void setup() {
 Serial.begin(9600);           // Start up serial comms
  servo.attach(11);     // Attaches the servo pin 11
  keypad.addEventListener(keypadEvent);     //add an event listener
}

void loop() {
 keypad.getKey();
 servo.write(0);
}

//take care of some special events
void keypadEvent(KeypadEvent eKey){
  switch (keypad.getState()){
    case PRESSED:
  Serial.print(eKey);
  switch (eKey){
    case '*': checkPassword(); break;
    case '#': password.reset();
    Serial.println("PLEASE ENTER PASSWORD");  break;
   case '0': changePassword();
    Serial.println("ENTER NEW PASSWORD");
    password.set(neKey));       break;
    default: password.append(eKey);
     }
  }
}

void checkPassword(){
  if (password.evaluate()){
    Serial.println("PASS CODE SUCCESSFUL");
    for(angle=0; angle<180; angle+=1){
    servo.write(angle);
    delay(15);
  }
    delay(5000);
    for(angle = 180; angle>=1; angle-=1){
    servo.write(angle);
    delay(15);
 
  }
    //Add code to run if it works
  }else{
    Serial.println("ACCESS DENIED! ,PRESS # TO RETRY ");
    //add code to run if it did not work
  }
}

void changePassword(KeypadEvent neKey){
  if(password.evaluate(){)
  switch (keypad.getState()){
  case PRESSED:
  Serial.print(neKey);
  switch (neKey){
    case '*': checkPassword(); break;
    case '#': password.reset();
    Serial.println("PLEASE ENTER PASSWORD");  break;
    default: password.append(neKey);
    }
    }
  }
  }

void changePassword(KeypadEvent neKey)``case '0': changePassword();
You promised you'd pass changePassword a single argument, but you didn't.

Thank you
