Amazon launches delivery service to the trunk of your car

(WJBK) - Nervous about having your package sit on the front porch all day? 

You may remember last fall, Amazon launched a new service called Amazon Key, giving us the option of letting a delivery person inside to drop off our packages. 

Amazon is now expanding that service to in-car delivery, meaning you can get your package delivered right to your car while you're at work, or maybe even on vacation. 

You don't even have to be there to get the package; the whole thing works using your OnStar or Volvo On Call account. (So, right now, the service is only available for Prime members with 2015 or newer Chevrolet, Buick, GMC, Cadillac or Volvos. It's also only available in 37 cities right now, with Detroit and it's metro area being one of them.)

When it's time to get your package, you'll have to set a delivery location and then you'll get a 4-hour window of when the driver's expected with your package. Then, when the driver finds your car by its GPS location, they'll request to unlock it through OnStar or Volvo On Call. The driver will leave your package and then relock your car. Then, you'll get a notification from your Amazon Key App when your car's been relocked. 

Amazon says special codes or keys are never provided to the delivery drivers, and everything is encrypted. They also say support for more vehicle makes and models will be added over time. 

Alyssa Bronikowski from Amazon joined us on The Nine to tell us more about Amazon Key. You can hear from her in the video player above.
