Wi-Fi Lockbox, can't find anything by googling?

Does anyone know if there exists such a thing as a Wi-Fi lockbox? I know there are Wi-Fi locks to control doors but I live in an apartment building and I cannot change the lock.

The situation is that my place is “Instant Book” ready with “24-hour Check-in” so sometimes I get guests who book when I’m not home and I’d like to be able to remotely change the password of the lockbox for that guest so they can show up and take the key when I’m not home.

When I Google’d it loads game up - don’t know which country you’re in but look on Amazon for starters. There are also some advertised through BNB partners o their website.
