Re: Dump your key locks and go combination
OK, just saw the bumpkey clip, and yes it is convincing, but uses the same principle as the key gun, which vibrates the pins instead of tapping them. Anyone with a little effort can purchase a key gun on the internet and do the same thing.
Left out of the report are a few details: 1) there are special pins and cylinder mechanisms which make bumping more difficult and might discourage entry; 2) mastered locks (those that take a master key) can sometimes jam if a certain procedure is not used when turning the cylinder.
So, sure, anyone can get lucky with this technique, but naive B&E artists will always get caught sooner or later.
BTW: possession of "burglary tools" is a felony in most places and will get you jail time.
