> What's the point of having these features in the app if you need to carry a key around all the time due to the app features being unreliable and poorly implemented? The point is that the key fits in your wallet. It's way nicer to carry, and then the phone gives you the convenience features that you'd usually get from a bulky fob, and much more. The app is anything but unreliable; in fact the keyless entry and walk-away lock features have worked completely flawlessly for me for more than a year (very uncharacteristic of a feature that relies on Bluetooth). An app malfunction is way less likely than my phone being lost or broken or out of battery; those are the more important reasons to carry the key card. If the car battery dies then the key card won't open the door. But the car also can't drive, and that seems like the bigger problem. Your ICE car also can't start with a dead battery, so being able to open the door is marginally useful. In both cases you need to fix the battery before you can drive the car. (Yes, there is emergency access to the battery without opening the door.)
