Technology for vehicles has advanced very far in the past decade. It wasn't very long ago that every single vehicle required a physical key, which required you to insert it into the lock to unlock it. Then came wireless fobs. Buttons on a small pad which would allow you to unlock and lock your car without physically touching it. The newest technology which still requires a fob, but it does not require you to do anything. As long as you have it with you, their car will automatically unlock itself when you are in range and lock itself when you are out of range. All you have to do is push the start button and you are on your way. All of this without even touching the fob. Now with 70% of Americans using smartphones today, a number that increases every day, the next generation of fobs will be your smartphone. Using Bluetooth technology, it will replace your fob completely. With major companies such as Volvo announcing that as early as 2017, they will be developing cars without keys, smart phones will be the future of your vehicle.
