One of the many things that Dead Island 2 has in spades, surprisingly, is doors. Of course, the game has an abundance of zombies, weapons, and loot for you to find and grab, but there are also a ton of doors to find keys for. Sometimes it's a lockbox, other times it's literally just a storage bin by a pool. Regardless of what it ends up being you will still need to find the key to open all these things, usually by looting it specific zombie corpses. The Police Dept Keycard is one of these items that you Dead Island 2 players will need to progress through the Venice Beach Police Department.
