Amazon’s mission: Getting a ‘key’ to your apartment building

Amazon is tired of ringing doorbells.

The online shopping giant is pushing landlords around the country — sometimes with financial incentives — to give its drivers the ability to unlock apartment building doors themselves with a mobile device. The service, dubbed Key for Business, is pitched as a way to cut down on stolen packages by making it easy to leave them in lobbies and not outside. Amazon benefits because it enables delivery workers to make their rounds faster. And fewer stolen packages reduces costs and could give Amazon an edge over competitors.
