Although this is a foriegn video clip it has subtitles, and it is important to know.

Um, I don't see any links, but if it includes the keygun, or other surreptitious entry devices, it IS good to know that mechanical locks alone do not make anything safe from a professional. In fact, you or I could open a majority of worn-out door locks with as little as four hours of practice.

Bump keys are very crude and extremely difficult to learn to use. Even an expert with a bump key will fail more times than they will get in. On the positive side, it is very quick, when it works and the user is unlikely to be noticed outside of the door. They are also small and easy to conceal.

More sophisticated devices are available, but not as portable as the bump key.

Would a good firewall not prevent this?

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.

Depends on if you have a locksmith liscense. Something always good to have lying around.

Or, I think True Crime Magazine has helpful advertisements in the back regarding procurement of certification for private investigation . . .

Overheard at a B & E trial: "But, your honor, I'm a certified PI!"

Very true. You can typically pick up a PhD for a bargain as well while you are ordering the locksmith license on the internet. Not as useful, but nice to have.

Here's a sport for all you danger-and-adrenaline junkies. For a few dollars you can get a key-in-the-knob doorlock and use it to practice. A lot of these have at least one spooled pin.

Combination locks aren't necessarily better by orders of magnitude, either.

I remember a window sticker that said: "These premises are protected by Smith & Wesson."

Perhaps cunning and vigilance are the best deterrents?
