You must have left the door open!

Confirmed by my local locksmith this morning, 90% of household locks can be opened with a bump key. There's a basic flaw in the design of locks that means simply by filing down a key
you can open any lock that key fits into by tapping it with something (like a screwdriver).

There are locks available that aren't vulnerable to this attack. They're going to cost you about $200.
