I have to say, now that we have a couple of months under our belts, that the unlock problem seems to have eased. Occasionally I need to swing my hip towards the car if it doesn't respond, but for the most part it opens right up. My Galaxy is in my pocket, her Pixel in her purse, and really you just have to have it close enough and it opens just fine. I've followed this thread and am grateful for all the input.
