amazon ups truck copyAmazon is devoting a lot of effort to prevent packages from being stolen from porches and outside homes.

The online retailer is making a new service available to Amazon Prime members in 37 cities, including Chicago, who own a 2015 or newer Chevrolet, Buick, GMC, Cadillac or Volvo. Those who can meet all these criteria will have the option of having their packages delivered to the trunk or back seat of their car, with a guaranteed safe delivery. These newer-model cars can be remotely unlocked, allowing Amazon's deliverers to receive a one-time access code to open the trunk in order to deliver the package. An alert is sent to customers once it is delivered.

In order to use the service, the customer has to park their car in a publicly accessible designated delivery location. Amazon then promises a four-hour delivery window, where the customer can track the progress of their package on the Amazon Key app.

The Amazon Key app was launched in November and was the first step Amazon took to prevent stolen packages. This app uses a camera and smart lock so Prime members can have deliveries brought into their home when they are not there.

The company plans on expanding this service to more cities across the country and make it available for more customers with different vehicle makes and models over time.
