Keys, including for my sister's house in town in case of need; car remote, Leatherman Squirt, and an LED torch which runs on 3 hearing aid batteries and is smaller than a AAA type. I don't want to load the keyring up too much because I often carry it in my pocket. The rest goes in my wallet (band-aids, sewing kit, emergency info) or my handbag, which is a whole 'nother story.
