How do guest codes work for Airbnb guests and cleaners?

Yes — this is one of the best uses for a keypad smart lock. Most apps let you create temporary or scheduled codes that only work between set dates and times, so you can issue a unique code per booking that automatically expires at checkout. You can also set a recurring code for a cleaner (say, every Monday), and delete any code instantly if plans change. For turnover properties, avoid sharing one permanent code with everyone, and keep a mechanical backup for yourself. Some hosts integrate codes with their booking platform, but always confirm the lock and app support scheduled access.
