Bump keys

Take a look at these

it looks that all (even those expesnive Gerda etc. locks) are vulenrable to this techique - what would you guys recommend as a viable alternative to the standard 'pin' based mechanism. One of the movies mentions a rotating cam design - any idea who makes something like that?

it has, but looking at the movie you realy get the frightening idea of how easy this is - using a lock pick you have to have that little pracitce and 'skill' in your hands, thus not everyone will be able to do it and it usually takes a bit longer. Here a guy (or gall for that matter) with a set of a dozen bump keys will be able to open almost every lock which is currently out there! What's worse. usually leaving no eveidence of a break-in, therefore good luck with a claim with the insurance agency.

p.s. in one of the other posts somebody mentioned Medeco biaxial locks as unpickable...are they also 'unbumpable'? T.P.

Yup, lets add them to the library of hundreds of video demos already out there, nothing new.

This technique does work well on most "standard" grade locks, IF you hold the specially modified key. An unlicensed professional being caught with such a key cannot easily explain away their criminal intent.

*most* manufacturers do provide higher security alternatives with sidebars, special pins etc. *most* property management companies are looking to manage their operating costs, period. *most* individuals don't deploy locks above standard hardware store shelf quality anyway.

Forensically it often leaves a trace ... a small square shadowy mark above the keyway where the modified key hits the top of the plug.

Are you speaking practically or definitively? Anything with moving parts can be defeated with the right approach, tools and enough time.

Locks of any kind ultimately only serve to provide a deterrent boundary, hopefully measured insightfully against the value of what is being protected.

Not really. Lots of locks will not bump open anywhere near that easily in actual usage. Most people who are so impressed with bump keying when they see it on a video have never actually bumped open anything much less gone out and tried it on numerous individual specimens. If you think it will magically work on every single lock that it should in theory you will be very dissapointed.

By 'unbumpable' I wanted to know if they are they safe against the bump-key technique. It is of course obvious that any kind of lock can be in some way or another opened

Could you take out the top pin and spring of one of the pinways so that when a bump key is used it bumps the free pin to lock the lock?

I wouldn't say that!!! I've done it and on more then one occasion. In fact used to pick open GM ING locks all the time for fun.

Yes. Use the longest possible pin. The only potential problem is that without spring force to drive the pin back down the lock may bind in any application where the plug is rotated beyond 90 degrees. Would probably work best on locks with fairly loose tolerances.

What does that have to do with Medeco? The only thing the two designs have in common is a sidebar.

The thing in common is they were "supposed" to be unpickable! I've seen the Medico bumped open on a few times!
