Delivery drivers call them “porch pirates.” It’s a derisive term for people who take advantage of the fact that many residents aren’t home during the day and swipe packages from doorsteps. Bad weather, nosy neighbors, or general privacy concerns may be other reasons you’re not comfortable leaving shipments unattended. Now, Amazon has a solution: Today, the company is introducing Amazon Key In-Car Delivery, a new method for dropping off packages that virtually guarantees they’ll be in one piece when you get home.

When shoppers opt for Amazon Key at checkout and own a vehicle that supports app-based unlocking, the delivery driver will be able to pop open your trunk and deposit your items inside. Essentially, your car doubles as a storage locker.

Your car may be sitting in your office parking lot during the day, but that’s no problem. Drivers will be able to pull up to your car there and make the same drop-off. When you’re done with work for the day, your packages will be waiting. Your car can be parked anywhere within a two-block radius of the delivery address and still be eligible for the service.

But how would a driver find it? The In-Car Delivery program requires a few things in order to work. For one, you need Amazon’s Key app; you also need to give the company permission to lock and unlock your vehicle. Your car must support app-based access, like 2015 or newer GM cars with OnStar subscriptions or recent-model Volvos with a Volvo On Call account. These vehicles have partnership agreements with Amazon that make them compatible with the Key software, as well as GPS functioning that allows drivers to find them when parked offsite. You’ll also need to be in one of 37 markets where Amazon dispatches their own delivery staff.

If this delivery approach is embraced, it’s likely that other carmakers will help Amazon widen their distribution platform. Amazon Key also offers in-home delivery service in select cities, which allows drivers entry into your home to leave packages inside.
