Amazon Key is now available for Sacramento residents.

The controversial program allows for Amazon delivery drivers to enter Prime customers home and place their packages inside. The program hopes to lower the amount of packages that are stolen from door steps and provide customers with peace of mind.

Customers who wish to take part in the program must purchase a smart lock and cloud cam security camera in order to ensure their safety. The entire delivery will be live-streamed using the security features.

Three varieties of smart locks that work with the Amazon Key in-home delivery service. They are from Kwikset and Yale. Also shown is the Amazon Cloud 

The price of the security features are steep, at $249.99.

The secure lock-service was announced last month for 37 cities, but didn't official begin until this week.
