Amazon Key

Amazon Key is a product developed by Amazon. It is based around a remotely-controllable lock which users can install in their front door. It allows Amazon to remotely unlock and lock the user's front door. In addition, using the included app, the user can remotely request that Amazon lock or unlock their front door for them.

This helps to alleviate the last mile problem by permitting the entrance of deliverymen to the house of people who have purchased and installed Amazon Key in their home.[1][2][3]

Amazon Key is designed to allow in-home delivery when the customer is not present. Customers will be able to watch the delivery and lock or unlock their doors. The service was launched on November 8, 2017 in 37 cities across the United States.[4]

A month after the service was launched, a security expert found a flaw in the system, which would freeze the camera, and prevent the customer from seeing what is happening in their home.[5]

Amazon provides this service by selling bundles priced from $250 composed of a camera (Cloud Cam), a Smart Lock and an app.


How it worksEdit

Amazon Key is meant to get packages delivered inside customers' homes, solving the last mile problem that made it difficult to deliver securely.

Once customers have checked the eligibility for the service and installed the kit, they will be ready to shop on Amazon and select the "Free in-home delivery". Right now, only Prime products are eligible for this service. Customers will be given a time window of 4 hours for the package to be delivered. The App associated to Amazon Key will send push notifications, notifying that the package will "arrive now". Then, customers can monitor on their device the delivery thanks to the Cloud Cam installed. As a policy of the company, the delivery agent will knock first the door before requesting access through the Amazon Key Scanner. Amazon will verify the location of the delivery agent and the order to be delivered before unlocking the door remotely, which activates the camera. Finally, the package is delivered inside the house and the delivery agent requests that the door is locked back again. The app associated with the service will constantly send notifications to the customers.[4][6]

Customers have the option of blocking access to their house through their Amazon Key app at any time and the delivery agents will proceed with the standard protocol.[4]

Moreover, it allows to customers to grant access to people they trust, such as family, friends or the house cleaner. They can set up permanent access or temporary access depending to the type of visitors.

Smart LockEdit

The Smart Lock devices included in the Amazon Key service are not Amazon branded but compatible smart locks; these are produced by Kwikset and Yale. These smart locks are installed in the customer's front door and provide access to people with the correct code, key or with Amazon's server authorization, allowing in-home delivery and guest access.[7]

Other usesEdit

Users with no Amazon Key service in their area can use the smart lock and the security camera separately as other smart home products. The products are not integrated but have a dedicated iOS and Android app to monitor its activity[7]

Cloud CamEdit

Amazon Key also includes the Cloud Cam, its first smart security camera that streams and records video in high definition (1080p). The main purpose of Amazon's Cloud Cam is to monitor the activity on your home, especially during deliveries using the Smart Lock.

The Cloud Cam is compatible with Amazon's Alexa, its intelligent personal assistant, allowing users to keep track of the activity on their home using only their voice and leveraging Amazon's cloud infrastructure, making the camera smarter with more features and advanced alerts.[4]

As other comparable security cameras in the market, the Cloud Cam exhibits full 1080P video capture, microphones that allow two-way communication, a night mode and the ability to review clips. Furthermore, users can get notified of any activity on the home with the App associated to the service.


Amazon Key is being sold under the Amazon Key In-Home Kit, which includes the Amazon Cloud Cam and a compatible smart lock. The bundle kit is priced from US$249.99, although it is possible to buy the different parts separately.[7]
