I understand completely!So that is a solid plan if one owns a vehicle and can come up with their own repeatable system. Problem is that when I travel and rent a car friggin' Avis has to put THREE of these things on one huge unbreakable lanyard. Some of these ridiculous "keys" are like half the size of an iPhone. I don't wear skinny jeans by any stretch, but there's no way I can function with 27 cubic inches of bulging rental keys in my pocket.
