How do you call this best in English? Like you have an assembly of keys, your house key, your basement cellar key, your bicycle key, etc. chained together with these keyrings. Key ring with keys? Bunch of keys? Batch of keys? Key bundle?
Like, you have this bundle somewhere in your room, misplaces and you want to exclaim "I can't find my key ___, have you seen it?" Or do you just say "I can't find my keys"? Would plural always suggest they are already bundled together?
In extention to that question:
How is this thing called? Key ribbon? Just keychain? How it called if the bundle is attached to this? Key bundle on a band...?
