To everyone who locks their carryon through security...
...what do you do with the key?
I bought a couple of very non-TSA-compliant luggage locks today for use on my rollaboard and my computer case, and it occurs to me that I'm not quite sure what to do with the key. Keeping it on me would alert the WTMD, putting it inside of my locked luggage would be, well, problematic, and leaving it in an exterior pocket defeats the purpose.
