On top of trying to survive in Dead Island 2, you will also be completing many missions. During these missions and while you're exploring, you'll have the opportunity to find hidden items throughout each area of the game. These items can include weapons, Easter Eggs, and keys.

One key in particular may have you puzzled in the Haus DLC. When it comes to the Forget Me Not key, it can be pretty difficult to find. This is especially true since you'll be fighting your way through zombies to reach each house while you search.

Forget Me Not Key Location in Dead Island 2 Haus

The Dead Island 2 character is showing where the location of the Forget Me Not key is in the Haus DLC.

As with other keys in the game, such as the mall cop's luggage key in Dead Island 2, this key is easier to find than you might think. Looking at the map, you will be going to the first house on your left that says "Keep Off The Grass". Head up the stairs and turn to your left. You'll see an open door at the end of the hallway; turn right and go up the next set of stairs.

Once at the top, you'll find the Secret Admirer standing in the middle of the room, surrounded by TVs. Luckily, she'll be unaware of your presence at first, so you should be able to get a couple of good headshots in. When you defeat her, she will drop the Forget Me Not key. You'll most likely have to fight your way out of the house.

Little Box of Secrets Rewards

The Dead Island 2 character is showing off the crossbow they received from using the Forget Me Not key in the Haus DLC.

At the end of the walkway to the house that had the key, veer to your left and head to the house straight down the sidewalk. Inside, take a sharp left into the living room, and you'll see some shelving with a yellow phone, some photos, and a red Little Box of Secrets box on the bottom shelf. Use the key on this box, and you will receive the rare Vigilant Crossbow valued at $8,835. Don't forget to find all the new weapons within Dead Island 2's Haus DLC as well.
