While most doors in Wolfenstein: Youngblood will be open or will open easily for you, there are some that require something more to get past. Some of these have number pads next to them that require a specific code if you ever want to open them. This guide will explain what you need to do to find these codes to be able to get past these doors.
How To Unlock Keypad Doors in Wolfenstein: Youngblood
As you could assume, keypad doors in Wolfenstein: Youngblood require a code to unlock. Specifically, they need a four digit code that you have to find elsewhere. Technically you could just try and guess the combination, but that would take forever.
Instead, you need to start looking for a floppy disk somewhere in the general vicinity of the door. This does not mean it has to be in the same room as the door, but at least somewhere fairly close to it.
Once you find the floppy disk, you need to decode the disk to get the information off of it, which you can find out how to do in our other guide focused on decoding. When this is done, you can now view the information from the disk, which should have the code included within it.
Now return to the door itself and interact with it by pressing X on Xbox One, or the respective button on other platforms. At this point, input the code you were given from the floppy disk and the door should open right away for you.
