I think it could be an isopod but am unsure. It doesn’t look like ones I am familiar with in houses (usually basements, which is not where this is).
It is about 10mm or 3/8" long, seems to move towards the top of the picture (but mostly is just wiggly), and is slightly hairy. Western USA.
I do! That is a key to a house I haven’t been to since 2018. It’s my package opening key 🙂 But good info to share! Don’t post your keys.
Ahh. Yeah I always mention it when people post keys just in case.
