I've noticed there are doors with a red padlock symbol in certain buildings, there's a locked door in one of the garages for example. Also chests around the city with the locked symbol also. How do I unlock these?

Doors are normally unlocked by either finding an alternate route and opening it from the other side or completing side missions.

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.
