Soon, we will finally be able to use key rings to store all of our dungeon keys.
(!empty($user->lang['CODE'])) ? $user->lang['CODE'] : ucwords(strtolower(str_replace('_', ' ', 'CODE'))):
We're pleased to announce that the keyring functionality has been completed and will be in place for patch 1.11. When a player first acquires a key, they will automatically acquire a keyring that will hold permanent dungeon keys. The size of this keyring will increase as the player goes up in level -- as seen below.
Level 1-40 = 4 slots
Level 41-50 = 8 slots
Level 51-60 = 12 slots
