Thank the Washington Post for this after they published a photo of the TSA master keys. Apparently, software is available that allows users to duplicate a key from a photo of the key. The photo was deleted from WaPo's article but not before it got circulated online by other sources. Photos of the keys are still available online. So now there are probably duplicate master keys out there somewhere. Don't you know baggage handlers in some of those high theft airports would like to get their hands on them, that is, if they don't already have a set.
NakedSecurity tells the story in TSA master luggage keys are 3D printed after photo published online.
Meanwhile, TSA itself has had to settle up with travelers to the tune of around $3 million from 2010 to 2014. See Lost, stolen, broken: TSA pays millions for bag claims, USA TODAY investigation finds. Click the link and scroll to the bottom of that article for a search engine for specific airports.
