Thanks for playing! There's a particular order the numbers need to be entered into the keypad - there's some clues throughout the game that should indicate the order they go in :-)
You tried them in different ways, but not the correct way ;-) In your video you got the numbers correct, but you never entered them in the correct order. Look at your surroundings for clues as to what order you need to enter the numbers, however the numbers change every time you play :-)
