that's been on all iPhone models since Apple first launched the iPhone in 2007, the new iPhone 15 Pro now has an"action button" that can be programmed to perform a shortcut of the user's choice.
While the button can be used to do things like open the camera app, start a voice memo, or turn your flashlight on or off, Tesla owners are using it as a key fob. With just a press of the one button, you can, open the trunk, crack the windows, or even get the AC going without turning on your phone's display or even taking it out of your pocket.
Teslas don't come with a physical key fob and are instead typically controlled through an app or unlocked with a key card (though Apple users already had the option of creating specific shortcuts for a variety of actions to control their car in their iPhones, available as virtual shortcuts through a widget or homescreen icon, but the new action button on the iPhone 15 Pro allows owners to trigger one of these shortcuts more conveniently and in a more tactile way, without even having to worry about waking up their iPhone or navigating the homescreen.
People have started publishing videos on TikTok and YouTube Shorts highlighting the different Tesla-specific shortcuts they're assigning to their iPhone's action button.
