Super useful and wonderful to use MAGNETIC separating key chain with double carabiners. This can be used to hook bags in place inside others, or as a key ring (probably wouldn't keep both carabiners on it if it was in a pocket) - but could be clipped to a belt loop or inside a bag pocket and yet simply pull the keys away and the magnets will let the keys do their job, then click back in place.
