Global e-commerce retailer Amazon has announced that Amazon Key delivery service which allows in-home deliveries and keyless guest access, will now give customers an option to get their packages delivered to their vehicles.

Amazon Key In-Car allows prime members to have their packages delivered to compatible vehicles parked in a publicly accessible area, typically at their home or workplace.

The ‘Prime members only’ service is available free in 37 cities across the US with same day, two-day and standard shipping options.

To use the service, customers need to download the Amazon Key app, link it to their connected car service account, and then register the delivery location.

“In-car delivery gives customers that same peace of mind and allows them to take the Amazon experience with them.”

Customers can place orders on the company’s website and should select the ‘In-Car’ delivery option at checkout to opt for the service.

On the day of delivery, the app will prompt customers to check whether they have parked the car within the earlier specified delivery location.

After confirmation, the app notifies the customer with an expected four-hour delivery time slot, the customer will be then notified when the package is on its way and once it is delivered.

The app’s activity feed allows customers to track when their car was unlocked and relocked.

Amazon delivery technology vice-president Peter Larsen said: “Since launching Amazon Key last November, we have safely delivered everything from cameras to collectable coins inside the home.

“Customers have also told us they love features like keyless guest access and being able to monitor their front door from anywhere with the Amazon Key App.

“In-car delivery gives customers that same peace of mind and allows them to take the Amazon experience with them. And, with no additional hardware or devices required, customers can start ordering in-car delivery today.”

The In-car delivery service is compatible with 2015 or newer Chevrolet, Buick, GMC or Cadillac vehicles with an active ‘OnStar’ account, and Volvo vehicles with an active ‘Volvo On Call’ account.

General Motors North America president Alan Batey said: “Unlocking Amazon Key In-Car delivery for more than 7 million Chevrolet, Buick, GMC and Cadillac owners is another great example of how we are leveraging the embedded connectivity in our vehicles to provide our customers with services that make their ownership experience more valuable.”

Volvo Cars chief digital officer Atif Rafiq said: “Simplification of experience for our consumers is central to Volvo’s digital vision. Receiving a package securely and reliably in your car, without you having to be there, is something we think many people will appreciate. Our partnership with Amazon now makes this possible for a majority of our customers in the US.

“This intersection between transportation and commerce could very well be the next wave of innovation, and we intend to be at the forefront.”

Currently available in 37 cities, Amazon plans to launch the service in other cities in the future as well as add more vehicle models.
