Thanks for replying. What you have is what I'm doing now.

I just transferred the items on my super keychain (which had become bulky and started clanking) into a zippered nylon first aid pouch after removing the first aid bits. I took each item off the super keychain's big splitring and tucked it into the pouch. I attached a smaller splitring to the hole in the pouch's zipper pull and, using a carabiner-style keyring, attached the pouch to the keyring holding my house and car keys.

The pouch goes where I do. Before I start my car I slip the car keys off the 'biner keyring. Not a bad setup. The red nylon case has First Aid printed on it and looks entirely innocuous. And no more clanking.
