Friends, where do i find the keys at to the rooms in my house..
Maria: You get her key after you start her chain. Just go to the weapon shop and make a copy.
MC: After you finish off the first part of Maria's quest go into her room and interact with the left shelf. You will find your key
Sarah: You get her key only if you pick her after you choose between her and Shasha during the late night date chain with her
Amy: start Amy's chain on day 35 or later. After you talk with Nersort and he tells you to speak with her go in the basement in the afternoon. speak with her here, and let the diolouge happen. after she leaves interact with her bag and get her key. After this go to the gun shop and make a copy then put the original key back.
Laura: After you finish the second shower scene with Laura in Laura's quest go to the Pharmacy and speak with her. She will then ask you to get the pharmacy keys out of her room and in turn will give you her room key. Make a copy of her room key, get the pharmacy key out of her room, and give her back the originals.
