Sense: noun/1
A key ring is the simple metal loop that holds your keys together. A keychain (also spelled key chain) is the broader term — it includes the key ring plus any attached strap, charm, bottle opener, or decorative holder. When someone says 'I got a new keychain,' they usually mean the decorative part, not just the ring. A split ring is the technical name for the coiled-wire design that lets you slide keys on and off; hardware shops and craft suppliers use this term. A key fob is a small ornament or electronic device attached to a key ring, often used for car remotes or security tokens — it is never the ring itself. Example: 'Rania picked up a leather keychain with a built-in torch, then added it to her key ring next to the car key fob.'

Etymology
Formed from the common nouns key (from Old English cæg, meaning an instrument for opening locks) and ring (from Old English hring, a circular band). The compound 'key ring' appeared in the mid-19th century, around the time when mass-produced metal split rings made it easy to keep multiple keys together in one portable bundle.
