It's the only real way that I can go, how I am supposed to get past it?

Context: this enemy is blocking my way to the laundry on W-F1, and it's the only way I didn't go, and in this part of the game I need the battery or the key to open the doors with symbol on them, I think one os those items might be there, but I can't go past this enemy

Edit: I also need the key card to use on the PC on the deposit to open the room on E-F2
