For dead rising 3 on the xbox one a gamefaqs message board topic titled locked doors.
How do you unlock locked doors in dead rising 3.
My suggestion is to do all the missions and side missions.

If you use xbox one smartglass on a tablet or smartphone or windows 8 computer you can get extra side missions which have codes as rewards.
Again there is nothing important behind these particular doors.
Search all round the building including the roof if possible.
Unlock the doors is the second story mission during chapter 7 in dead rising 3.
Some buildings have multiple ways in and the door can then be opened from within some doors are opened during main missions and others open during side missions.
The locked doors are all accessed by completing the main story and side missions which will give you access to all actually there are many doors that you need smartglass to open.
As for the zdc locked boxes around the map you need to download the xbox one smartglass app and receive side missions to unlock them.
Just do side missions follow along with the story.
Doors are normally unlocked by either finding an alternate route and opening it from the other side or completing side missions.
He will need to find a way to unlock the doors to escape the metro station.
Some of these side missions result in opening those doors.
