We got some screenshots of the mobile app for the Model 3.https://www.teslarati.com/tesla-model-3-app-phone-key-features-screenshots/
I thought the trunk was manual? So how is the "trunk" button different than the "unlock" button?
Valet mode is set by the app so I guess you can't have a separate valet card.
Model S & X doesn't have a different fob for valet fob.
Since Model 3 uses key card instead of fob: no valet key card.
"trunk" button different than the "unlock" button?
Just as in S & X, when you remotely "Unlock", your friends can manually pull the doors open and push a trunk button to open trunk at that time (and climb into the car to push on the display the frunk button to open the frunk.
It seem that with Model 3's app, your friend does not have to climb into the car to access the center display to open the frunk. And your friend doesn't have to manually push the car's trunk button to open the trunk.
Those are two additional superior remote features that more expensive S & X don't have.
