This lock needs a 4-digit number.
THE TIME DOOR
On the back of the card with an hourglass (“time”) and a door (“door”) is a grid corresponding to the license plates. When placed correctly, the filled-in plates' state abbreviations spell DE-CO-DE-GA-NY-ME-DE, or "Decode Ganymede".
Using the list of Jupiter’s moons found inside the vault, there are two numbers in the line for Ganymede. One of them opens the door.
