I have a single truck key in my wallet.
Full set of keys in my truck.
Full set of keys in my laptop bag.
Neither of these, I am very far away from.
Full set of keys I carry at all times in my pocket, or in my hand.
Basic set in my kitchen drawer and office drawer at work.
I'm a tad obsessed about locking myself out. In fact, I will not close my truck door while outside of the truck without having the keys in my hand, even tho I know they are in my pocket, and a backup in my wallet. The other thing that negates this is if one window is rolled down.
Sound a tad weird
