Hmmm. Will the physical card key not do the same for you? I keep one in my wallet. Granted, my wallet is usually in my car, but the iPhone works 100% and have the watch as a backup or primary if at the beach.I have to use a fob because the car won't present the handles half the time with my phone in my back pocket. Unlike our Y, unless the handles present, you can't get in the car without touching the handle if it's stowed. Not having a fob for the Y is fine.
