I have keys but they cannot open. I have Mice that are beloved I am a state but not of matter

A monster, a song, a drink once bitten, you won't think

I'm untanned, but cool. People may admire be, but I suck. At night I may be batty or hungry like a wolf.

I’m zeros and ones, I answer without feeling. I can make decent content, but not without stealing. I make six fingered hands, I’ll respond in a flash. I may be quite useful, but my riddles are trash.

An amazing person who should have pride, my words speak no lies. Look to the mirror and you will see, a fantastic individual, I hope you'll agree
