Stepper + Keypad + Password

Hi, I wrote this code, but its not working. I create 3 passwords. If I digit some of this correct password in keypad 4x3, the stepper will turn some steps. But my stepper is not working... I think is something wrong in the code...

Sorry my English.

#include <Keypad.h> //Biblioteca do teclado
#include <Password.h> //Biblioteca das senhas
#include <Stepper.h> // Biblioteca do motor de passo

//Código do teclado

const byte LINS = 4; //Quatro linhas
const byte COLS = 3; //Três colunas
char tecla[LINS][COLS] = {
  {'1','2','3'},
  {'4','5','6'},
  {'7','8','9'},
  {'*','0','#'}
};
byte linPins[LINS] = {2, 3, 4, 5}; //Conectado nas linhas de saída do teclado
byte colPins[COLS] = {6, 7, 8}; //Conectado nas colunas de saída do teclado

Keypad teclado = Keypad( makeKeymap(tecla), linPins, colPins, LINS, COLS );

//Código das senhas

Password senha0 = Password( "123" ); //Senha correta 0
Password senha1 = Password( "456" ); //Senha correta 1
Password senha2 = Password( "789" ); //Senha correta 2

//Código do motor de passo

const int totaldePassos = 64; //Números de passos total do motor
Stepper motor(totaldePassos, 9,10,11,12); //Inicializa a biblioteca "Stepper", conectada nos pinos 9 a 12

//Setup do código

void setup() {
  teclado.getKey();
  motor.setSpeed(300);
}

//Loop do código

void loop() {
}

//Teste da senha

void colocarSenha(KeypadEvent eKey){
  switch (eKey){
    case '*': confirmaSenha(); break;
  }
}

//Confirmação da senha

void confirmaSenha(){
  if (senha0.evaluate()){
    for (int i = 0; i < 32; i++){
      motor.step(32);
    }
  }
}

But my stepper is not working.

Does it work with the sample that comes with the Stepper library? If not, it isn't a software problem.

  teclado.getKey();

Get the key that was pressed. Throw it away. Useful?

void colocarSenha(KeypadEvent eKey){

What makes you think this function will ever be called? Nothing tells the Arduino that it should be called.
