Grip's key

Grips' keyring is an item that players obtain whilst doing the Heroes' Quest, if they are in the Black Arms gang. They can only obtain this item after their partner kills Grip with ranged attacks.

The key is used to unlock the door to a treasure room in ScarFace Pete's house in Brimhaven in order to obtain the candlesticks required to continue the quest.

This is one of the keys that cannot be held on a Steel key ring.

Regardless of its name, the "key ring" does not seem to be a key ring, due to the fact you cannot put keys onto it.
