The thing is that they have hardened steel pins in the right places (the
wrong places for the locksmith). Because they are hardened steel, you
have to use very brittle carbide bits. Because they are pins, you are
trying to begin a hole on a rounded surface. If you happen to be lucky,
you will hit dead center and have a decent chance of going through
(eventually). But often, you won't hit dead center, and the round
surface of the hardened steel pin will send your bit on a detour, a
detour you don't want, a detour that will probably break your bit, which
puts a new hardened steel oddly shaped object in your way, making it
that much more difficult still.
I don't necessarily buy this. I probably would never drill a lock with
a carbide bit. Personally, I'm at the stage where I just don't really
use carbide bits very often, anymore. High speed steel works for 90%
of what I need; diamond bits work for the other 10%. Carbide has such a
narrow range of applicability anymore that you have to have a very
specialized application to make it worthwhile.
In addition, I'm not sure I would "drill" a lock anymore. Why not use
something like a plasma cutter? They aren't that expensive; about 5x a
good drill that would work for drilling a lock.
Schlage Primus is one
that is close to pick proof as well as a few from Assa and others.
The guy who developed Schlage Primus is the same guy who invented the
Medeco design from what I've heard.
Myself, I figure the average methhead in my neighborhood is just going
to hop the fence to my backyard and pop a window. I really should get
some shatterguard to put on them.
Medeco is an Assa company, apparently.
The Medeco locks are far from pickproof. However, they require a cut
above in skillset. J. Random Schmuckwad is unlikely to have the
experience with the lock to acquire the skills to pick the lock.
In addition, they require much more sophisticated machinery to create
duplicates since they rely on angled keys to raise the pins as well as
just basic height.
All in all, though, it looks like a very nice lock.
