Can you give me the room key, please?
CHIA-ve — two syllables, stress on the first. The 'ch' is always hard in Italian, like 'k'.
After completing check-in paperwork. Some older Italian hotels still use physical metal keys rather than cards.
'Mi può dare' uses the modal verb 'potere' in the third person formal (Lei form). This is the polite way to make requests at a hotel front desk. 'Mi' is the indirect object pronoun 'to me'.

Useful for couples sharing a room

What to say if you lock yourself out
Many Italian hotels ask you to leave your key at reception when going out. This is both a security tradition and an energy-saving measure — older buildings often use the key to activate electricity in the room.
