There's usually a box by the front desk to drop off the keys so they can be reused. In some cases, there's an option to check out on the TV's interactive menu or the phone system, which lets them know you're done with the room. Many hotels now can simply email you a copy of the bill as well.

In 2026, the standard protocol for hotel keys depends on the type of technology the hotel uses. For traditional plastic RFID key cards, the most polite and efficient method is to leave them at the front desk upon checkout so they can be sanitized and reused, reducing plastic waste. If you are in a rush and using "Express Checkout" via the hotel's app, most 2026 hotels have a designated drop-box near the lobby exit or elevators. If you are using a Digital Key on your smartphone, you don't need to do anything physical; once you "Check Out" in the app, the digital token is automatically deactivated. For boutique hotels that still use physical metal keys, you must return them to the front desk agent personally, as losing these often incurs a "re-keying" fee of $50–$100. It is generally discouraged to leave keys inside the room, as it makes it difficult for housekeeping to know if you have officially vacated the premises, potentially delaying the room's turnaround for the next guest.
