Security System

I have been making Password based Security system with using password.h and keypad.h libraries.i use arduino UNO for this security system. When i program this security system i face small problem unfortunately. I need to get new function when i type password to the opposite side. how i do i it?

void keypadEvent(KeypadEvent key){
  switch (keypad.getState()){
    case PRESSED:
    if(key == '#')
    {
      
      LcdClear();
      gotoXY(6, 0);
      LcdString("Enter Your");
      gotoXY(13, 1);
      LcdString("Password");
      gotoXY(0, 2);
      LcdString("============");
    }
   
	switch (key){
	  case '*': checkPassword(); break;
	  case '#': password.reset(); break;
	  default: password.append(key);
     }
  }
}

void checkPassword(){
  if (password.evaluate())
  {
    gotoXY(16, 4);
    LcdString("Correct  ");
    gotoXY(13, 5);
    LcdString("Password  ");  

  else
  {
    gotoXY(20, 4);
    LcdString("Wrong  ");
    gotoXY(13, 5);
    LcdString("Password  ");
   
  }
}
