There were 2 problems with the lockbox at the AIRBNB we went to in Oakland.
1 The lockbox is 13 inches above the ground which makes it very difficult to access. 2 The lockbox is old and almost impossible to open. After multiple tries we called the host multiple times. The host finally told us we may need to use something to pry it open to get the house key. I do not carry a pocket knife. After 35 minutes of trying I emptied most of my suitcase into the trunk of our car and found a small screwdriver. Then I was able to pry open the lockbox.
