This is a fancy version of "Lights Out". Clicking a button on the keypad will toggle its corresponding LED. To unlock the door, all of the LEDs must be turned off. Click the screws to take off the panel. Then press the buttons to get all of the LEDs turned off. Press the red Reset button if you want to start over. All puzzles take at most 5 to 9 key presses to solve. Click the brute forcing tool to have it randomly guess for you. Shift-click the Green Flag to enable turbo mode (otherwise it goes too slow.)
