Focus In Jframe

Question

I am trying to have a key listener inside a Jframe which will work no matter where the focus is, currently it only works when the focus is at certain locations. How can I do this, here is where I create the frame and components and attempt to get the keylistener to work....
import java.awt.*;
import javax.swing.*;
//import cs1.*;
//import java.io.*;
import java.awt.event.*;
//import java.applet.*;
class Driver extends JPanel implements ActionListener, KeyListener
     static String title = "Number Munchers";     //Game title
     Board board;                                        //Game board
     public JFrame frame;                              //Game frame
     protected JButton b1,b2,b3,b4,b5;
     Score s1=new Score();
     Monster monster1;
     public void createAndShowGUI()
          frame = new JFrame("Number Munchers");
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.addKeyListener(this);
          board = new Board(this);
          JMenuBar menuBar = new JMenuBar();
          JMenu fileMenu = new JMenu("File");
          JMenu optionMenu =new JMenu("Options");
          JMenuItem start = new JMenuItem("New Game");
          JMenuItem end = new JMenuItem("End Game");
          JMenuItem sound = new JMenuItem("Sound On");
          JMenuItem mute = new JMenuItem("Mute");
          start.addActionListener(this);
          start.setActionCommand("New Game");
          end.addActionListener(this);
          end.setActionCommand("Exit");
          sound.addActionListener(this);
          sound.setActionCommand("Sound");
          mute.addActionListener(this);
          mute.setActionCommand("Mute");
          menuBar.add(fileMenu);
          menuBar.add(optionMenu);
          fileMenu.add(start);
          fileMenu.add(end);
          optionMenu.add(sound);
          optionMenu.add(mute);
          frame.setJMenuBar(menuBar);
          //Add Number Muncher game board to frame
          frame.getContentPane().add(board,BorderLayout.CENTER);
          //Add score to frame
          frame.getContentPane().add(s1.scoreLabel, BorderLayout.NORTH);
          //frame.getContentPane().add(l1.livesLabel, BorderLayout.EAST);
          //Add info to frame
          frame.getContentPane().add(board.getGameLabel(), BorderLayout.EAST);
          frame.getContentPane().add(board.getScoreLabel(), BorderLayout.NORTH);
          frame.getContentPane().add(board.getLivesLabel(), BorderLayout.SOUTH);
          frame.setSize(550,550);
          frame.setVisible(true);
          monster1 = new Monster(0,0,this,board,board.muncher);
     public static void main (String args[])
          final Driver driver = new Driver();
          javax.swing.SwingUtilities.invokeLater(new Runnable()
               public void run()
                    driver.createAndShowGUI();
     }//End main method
     public void keyPressed(KeyEvent e)
          System.out.println("Key pressed");
          if(e.getKeyCode()==KeyEvent.VK_LEFT)
               System.out.print("LEFT ");
               board.move(-1,0);
               System.out.println(board.muncher.returnY() + " " + board.muncher.returnX());
          if(e.getKeyCode()==KeyEvent.VK_RIGHT)
               System.out.print("RIGHT ");
               board.move(1,0);
               System.out.println(board.muncher.returnY() + " " + board.muncher.returnX());
          if(e.getKeyCode()==KeyEvent.VK_UP)
               System.out.print("UP ");
               board.move(0,1);
          if(e.getKeyCode()==KeyEvent.VK_DOWN)
               System.out.print("DOWN ");
               board.move(0,-1);
               System.out.println(board.muncher.returnY() + " " + board.muncher.returnX());
     public void keyTyped(KeyEvent e)
     public void keyReleased(KeyEvent e)
          if(e.getKeyCode()==KeyEvent.VK_CONTROL)
               System.out.println("MUNCH");
               board.munch();               
          if(e.getKeyCode()==KeyEvent.VK_ENTER)
               System.out.println("REFRESH BOARD");
               board.refresh();
     public void actionPerformed(ActionEvent e)
          //Menu Bar
          if(e.getActionCommand().equals("New Game"))
               System.out.println("New Game");
               board.clear();
               s1.refreshScore();
          if(e.getActionCommand().equals("Exit"))
               JOptionPane.showMessageDialog(frame,"Are you sure you want to exit?");
               System.exit(0);
          if(e.getActionCommand().equals("Sound"))
               System.out.println("Sound On");
          if(e.getActionCommand().equals("Mute"))
               System.out.println("Mute");
} //end Driver class
If you can help thanks a lot, this is a problem I have spent a long time attempting to fix.
