At the rate thumb drive prices are dropping, the key caddy will soon cost almost as much as the thumb drive.

How about clipping it to a Swiss Arm “Classic” or mini pocket knife, the kind that comes with a small pair of scissors, a nail file, and a small unlocked blade?

Here’s the Classic from the Target website:

I keep my “condo complex” entry key on a small key chain with a mini Swiss like that, plus a miniature key-chain Photon light. Very handy set up. Doesn’t put me at risk for dropping my main set of house keys or car keys down the crack between the steps at the entry. (Stuff like that happens. But not to me.)
