Apple, wants to replace the keys with iPhone and proximity sensors

The Apple just patented a patent which could be used in your iPhone and a car equipped with CarPlay, to unlock the doors, opening the trunk to open it or heating. The main thing is that all this is done without taking off your cell phone from his pocket. 

Rather than replace your key with an application that lets you unlock the doors to start the engine or download below the windows, which already offers the GM, the Apple the go a step further by using proximity sensors. 

More specifically, using the technology of Apple iBeacon to connect with the car or a location based vCard, when you approach the car a range of actions can be triggered. The patent describes that depending on the place where you are around the car, it will open for example the trunk or unlock the doors. But the idea does not stop here. 

With the car connected to the network (by 2020 it is estimated that 150 million cars will have a data connection), the sensors will recognize the iPhone user's movement in the street, at home and in the office and can predict that for example to heat the water when he goes home and opens the heating when you arrive at the office. 

Of course all this is a patent, as it currently only offers Ferrari cars equipped with CarPlay. But the question remains today what it is when you run out of battery.
