Amazon Key is essentially a smart lock that allows users to control remotely and let delivery personnel place goods directly into the users homes.

Users of Amazon Key can also create temporary passcodes for friends and other services to enter as well.

The idea is essentially to allow those who cant make it home for a delivery (which is practically everyone)  peace of mind that their package won’t go missing from their doorstep.

“This is not an experiment for us,” said Peter Larsen, Amazon vice president of delivery technology, in an interview. “This is a core part of the Amazon shopping experience from this point forward.”

Members of Amazon’s Prime shopping club can pay $249.99 and up for a cloud-controlled camera and lock that the company offers to install. Delivery associates are told to ring a doorbell or knock when they arrive at someone’s house. If no one greets them, they press ‘unlock’ in a mobile app, and Amazon checks its systems in an instant to make sure the right associate and package are present.

The camera then streams video to the customer who remotely can watch the in-home delivery take place. The associate cannot proceed with other trips until the home is again locked.

But persuading users that this is a safe device to use is going to take some pretty fancy marketing.

Amazon’s new service goes live on Nov. 8 in 37 U.S. locations
