Wow, that's bad. It's a good thing my front door has a keypad front lock on it, no slip key is good for that, and the keypad locks out after 3 bad tries for a half hour.
Yeah, bump keys are bad. The good news is that a key shop wont make them. Speaking as a police officer, I don't see them used, But, I learned of them last year online, I actually ordered one online just to see how easy it was. It was infact easy.
