The benefit to a code lock for me over a box with a code that holds the keys is there's no key to lose nor any key to forget to return. I don't even have to carry the key when I go out. One less (three less?) things to worry about. I actually locked myself out of the last AirBnb I was at. I forgot the key and while that meant I didn't lock the door to the apartment there was also an automated door to the building. Going out it auto-opens, going in it requires a key. I just sat in front of the building for 30 minutes until someone else opened the door. I've stayed at about 15 AirBnBs, most of them I didn't have to meet the owner. But, also most of them used a lock box with a code instead of just a door code lock.
