Hunter's comment
The Smart Key is designed for rental hosts, home or property owners. It is a simple device that will make things much easier for you. If you need to leave some keys somewhere & give someone access to something, then this is a perfect solution for you.
It looks like it takes at the most, 5 minutes to setup. You can place multiple keys & key cards inside. Maybe you need to leave someone a gift card when your not home. Then you could do it with this.
