I do have the keycard in my wallet but often travel without it. On longer trips, my wife is usually with us so we have two phone keys and the likelihood of both of us forgetting to charge are slim ( also, the wireless pads in the car is where you usually store it )

Additionally, if I were to be stranded somewhere there are 2 other people with phone keys that I could contact for them to remotely open the car, or just find a charger somewhere.

I have had more bad luck losing physical phone keys in the past.
