A:Answer There is a smart app for locks (look for the smart app menu under the main menu on the upper left of the app, it is called Smart Lock Guest Access) that allows you to assign up to 5 guest codes for a lock (I’m using Schlage). Each gets a name, and you get a notification when they are used (I think you can turn this off, if wanted). So, yes, you can do this - but it needs the added smart app.
