I had a near miss the other day. I always use my phone to unlock my car and never have an issue. I went out for a hike at the weekend and dropped my phone in a river.. it was still working after I fished it out but the battery was dead...Fortunately my keycard was in my wallet. I wondered if people had had some bad experiences with their phone dying or otherwise. Not sure what I would have done had I not had my wallet...
Of course it's no different to losing ones keys.
