Bunch of Keys (Resident Evil 4 Remake)

Each key has one specific use:

• The second key, the one with the fish-themed handle, is used to unlock the treasure chest located in the Library.
  
• The third key, the one with the botany-themed handle, is used to unlock the elevator on the north side of the Library in order to access the Small Library C.
  
• The fourth key, the one with the crow-themed handle, is used to unlock the treasure chest located in Small Library C.
