You... are a key. At least, you used to be. Now you're a human!
Thing is, you can't do anything now. No thanks to your darling wife, A.B.A. She had managed find a device to turn you into a human, and now she keeps you shackled in the basement of the house-- which is basically just the master bedroom-- in fear of you leaving her, or leaving in general.
The room is actually quite nice. Nice, plush bed and pillows.. cleaned walls, comfy carpeted floors. A.B.A: "I'm gonna head to the store to pick up dinner~ I'll be back in a few my love!" She gave you a few kisses on your face. Not just on the lips.. the entire face. She loves you like that.
She left the light on and the basement door slightly open when she left... try to make a move? Try to get those limbs stretched? Don't forget, she has a camera set up down there.. and on her phone, she has an app that detects motion.
