Trying to locate the missing suitcase... 
And on that point, my new suitcase (my favourite Samsonite having let me down after about a billion years and a trillionteen miles of travel) has a combination lock and a key release so that 'security' can gain access to it if they need to search the contents... 
...I suppose there is no chance of the case stompers ever getting hold of the key...? 
Oh it's worserer than that. A well known newspaper published a photo of them some years back and as a result you can now download the 3D printer files to make copies. Not that they looked like very sophisticated keys
I could post up the link to the files but I guess that'd be a bit naughty

The classic problems with 9 out of 10 security systems
- designed by a JAFA (Just Another Fucking Amateur) masking as a professional
- designed by one but millions trying to break it, at least one will always get lucky
- relies on a secret that is known to thousands more people every day
- never properly audited
