Seriously NFC or Bluetooth port this functionality into the phone app at this point. My standard fob is too big as it is when its on my keyring, which only has like 4 keys on it. This is an utter waste of R&D time and money when an app can and would do the same thing without as much added cost and bulge. Sure you'd have to change something on the car receiving end but as people above have said if a phone is secure enough for financial transactions its easily secure enough to start/lock/unlock a car.

I'd happily pay whatever premium they are looking to get for the key to have the same functionality in my phone, but I would never want an even bigger key fob (or phone)!
