It don't look like any key I've ever seen.

Way too long.

And added note. The walking dude definitely looks to be on guard and ready to get down at a moment's notice.

He looks like a furly dangerous man.

Still, not a key, in my estimation. Something else.

p.s. How did the anons make the connection to that mobster?

Bagster

Could be a push dagger.

It looks like a Jaguar or Lexus key. Could be Mercedes, I don’t know.
