From the article here: https://www.theverge.com/2018/3/28/17168192/lincoln-aviator-hybrid-ny-auto-show-2018 It sounds like this will be 2020 model but still a lot of it sounds very familiar .... "The Aviator will also be the debut of Lincoln’s new “Phone as Key” technology for those who bristle at having to use those easy-to-lose, outdated key fobs. Owners can lock and unlock the vehicle, open the trunk, and start the car and drive it, all with just a smartphone (and the automaker’s “Lincoln Way” app). They can send a temporary code to others, like a teen driver or a valet, for short-term needs. No worries about someone running off with your ride, though: the code will eventually time out." No mention of whether or not the phone will be the only method, I assume not and that a FOB will be, at least, optional.
