To find the Maintenance Toolbox Key needed to open the BWRP Maintenance Toolbox in Dead Island 2, travel to the Brentwood Sewer.
Once there you’ll find the Maintenance Worker. Take him out then loot the Maintenance Toolbox Key he drops. Now that you have the key, make your way to the room south of the Main Septic Tank. It’s on the second level of this area.
In the office area, you’ll find the BWRP Maintenance Toolbox. You’ll now be able to loot this box to receive a Leeching Zombie Axe.
