Your first time taking control of Carlos in Resident Evil 3 has you returning to the iconic Raccoon City Police Department. While a lot of the locker and safe combinations are the same, this time the Safety Deposit Room where you get the shotgun in Resident Evil 2 with the Weapons Locker Key Card will be locked and you’ll have to search the RPD for the key.
Opening the Safety Deposit Room in Resident Evil 3
The key to the Safety Deposit room can be found on the 3rd floor of the RPD. Head down the corridor to the right of the room(the path to the safe room next to the stairs) and head up the staircase. Head up to the third floor and on your immediate left there will be some cardboard boxes and the key will be laying on top of them. There will be several zombies here and a licker, so do your best to avoid or engage them and then head back to the Safety Deposit room.
Use the key on the door and head inside. There are three lockers you can open on including the battery you’ll need for the C4 to continue through the RPD.
