Online retail giant Amazon has announced that tens of millions of its Prime members will have access to Key by Amazon’s in-garage delivery service in more than 4000 cities across the USA.

Key in-garage delivery lets eligible Prime members enjoy contactless package delivery securely inside their garage, and offers convenient delivery confirmation for customers using the Key by Amazon app.

“Customers tell us they appreciate the convenience and peace of mind that in-garage delivery offers, and we’re happy to expand the service to thousands of additional cities,” said Pete Gerstberger, head of Key by Amazon. “With this latest expansion, Amazon customers in thousands of big cities and small towns across the USA can now enjoy another Prime benefit with convenient, contactless deliveries right in their garage, all backed by the Key by Amazon happiness guarantee.”

Key in-garage delivery lets eligible Prime members with a MyQ smart garage door opener receive packages securely inside their garage. Once they link their MyQ app with Key, they simply select free in-garage delivery at checkout on the web site.

Packages are securely delivered by a delivery service professional, and customers can use the Key by Amazon app or the Amazon mobile shopping app to be notified when their package is delivered. To view videos of their delivery, they can also use a compatible Ring smart home camera or LiftMaster smart garage camera powered with a MyQ video storage subscription.

Originally launched in 50 cities, the service is expanding to more than 4000 cities and towns across the USA including New York, Los Angeles, Chicago, Philadelphia, Dallas, Washington DC, Houston, Boston, Atlanta and Phoenix, and thousands of surrounding areas.

In addition to expanding in-garage delivery, Amazon is also launching Key in-garage grocery delivery. Beginning this month in five cities, this service enables eligible Prime members to have their grocery orders from Whole Foods Market or Amazon Fresh delivered securely into their garage. The service will be available in select areas of Chicago, Dallas, Los Angeles, San Francisco and Seattle before expanding to other cities in the USA.
