How To Start A JPanel After Switching

I am creating a Pong clone with a menu and the actual game itself. I am using a CardLayout to switch between the two JPanels.

However, when I switch from the menu to the board (or playing area), the board just sits there and won't accept my keyboard inputs. How do I start it or start the key listening?

for CardLayout the listener should have these codes

 CardLayout card=(CardLayout) JPanel_with_cardLayout.getLayout();
 card.show(JPanel_with_cardLayout,"cardname of card you want to switch");

example:

CardLayout card=(CardLayout) JPanel2.getLayout();
card.show(JPanel2,"card4");

Answer (as recommended to you previously): Don't use a KeyListener. use Key Bindings.

requestFocusInWindow() should do the trick.
