Heath, just a suggestion for your consideration.  Don't set off
a smoke pot in a public building like a school.  The darn thing
will trigger the smoke alarm which will set the fire bells to
ringing, resulting is a visit from the entire fire department.
A former student of mine had that experience!  Embarassing?  You bet!

     I haven't been picking locks for very long and all of my knowledge
comes from trial and error, if anybody is willing to entertain my questions
I would be most grateful.


     1>  Desk locks, file cabinet locks and even some door locks are a
       snap.  Most door locks, however, are completely above my skill
       level.  What makes one lock easier to pick than another?  For
       example, I am able to open the lock in the doorknob of my
       aparment door with no problem but the deadbolt above it won't
       give in even though they both use the same type of blank.

     2>  After one of these attempts at my deadbolt I usually end up
       sweaty and frustrated.  I also usually end up distorting my
       tension wrench.  Is this bad?  Am I applying too much pressure?

     3>  The only picks I have found useful so far have been my diamond
       and my rake.  Are the others just for show?

There is a thing called the REED GENERAL CODE
BOOK which is 10 volumes of key codes and
combinations.  It is used by locksmiths for
creating a key from a code number.  It also
contains combinations for master locks.

It is also available as a program on an IBM
Compatible.  A fantasy of mine has always been to
buy the program ($595) and set it to be accessed
on the network as a mail server.  Right now its
beyond my grad student budget.

As for an algorithm, I assume you mean something
other than table lookup, and the answer that I've
read in technical publications is no.

Yep, and a federal offense, too.

On a related note, I've heard that modern fire alarms in buildings, (the
kind you set off, not the automatic kind) have the paint spraying
mechanisms similar to the ones in bank bags.  (Explode on you, literally
painting you red.  Sometimes blue.  Impossible to wash off).  True, not

(That's "key blank" or "keyway" J.)

Funny - I would have guessed Best, but his picture of the key didn't show
the shoulder stop on the bottom (Best keys are measured from the tip back,
whereas most cylinder keys are measured from the bow forward), the
"really short flat spots" didn't make sense (the picture showed them
as being half the width of a normal cut), and I'm not familiar with any
Best cylinders that have concentric rings at the back.

Best does do custom blanks.  I've never seen theirs, but what I've done
for other restricted blanks is grab a key blank reference, find the blank
that's closest, and use that with a little hand-filing to make it fit.

This is true, but they also serve another purpose.  I _know_ people that
didn't pull the alarms at my school because they were supposedly
dye-trapped.  I spent two months of nights getting woken up about 3 times a
week at all hours of the night due to spurious fire alarms.  If dye-traps
deter people I am ALL for them.

This is my first time posting, and my answer has probably already been discussed.

A guy once told me if you dissolve salt in some water, heat it up, add some
more and so on  (Super-saturating) and then put it in a squeegee bottle and
then
squeeze it into the coin slot, you are supposed to get a lot of cokes or pop.

I actually tried this once, but it didn't seem to work.  I heard that when you
put a quarter into the slot, it makes a connection from one side to the other.
Like I said, it didn't seem to work, but maybe someone else wants to try it!

Yes, it's called a slap hammer.  It's meant for pulling out dents in cars.
It has a hardened screw that you screw into the sheet metal (or cylinder),
and a lead weight on the rod.  You slide the weight back away from the
car, and when it hits the handle, it yanks on whatever the screw was
fastened to.

*Probably* not, although I haven't tried it.  There's a lot you'd have
to shear to get the plug out; you're more likely to just pull the screw
out of the keyway.

	Maybe I was not clear but I would say that you are still wrong
	Mr. Margolis. Let me show you why.

	Suppose you go to a terminal connected to an open terminal server.
	Usually these open terminal servers let users connect only to 
	the machines of a local netework, for example the physics dept. net.
	But sometimes they do not have any type of  restrictions, and
	they let you telnet any machine in the reachable worldwide network.
	But this does not matter, you can still post from a local machine.

	So one sits at one of these terminals and without even having an
	account anywhere in the world, telnets the NNTP port of any
	machine and posts the article,   or sends the mail.
	Then the machine where the posting is being made, ONLY knows
	that the posting came from the physics dept. terminal server.
	So no matter if we are talking about a large government agency
	or a local system administrator, I would say that the only thing
	which can be determined is that the posting came from a certain
	terminal server, which probably serves many computers, and
	hundreds, if not thousands of users. This is the same as
	saying that the originator of the posting is untraceable.

	Unless they get your fingerprints from the terminal
	keys or something like that.

	This open terminal servers are NOT SO UNUSUAL, even in 
	my limited experience with computers.

	What may happen as somebody pointed out to me by mail
	is that this might result in pressure to restrict the
	terminal server to certain ports. 
	If somebody can send comments about this it will be appreciated.

  Aha - what I consider "good" ones have a 90 degree bend in the
handle near the L bend - so now they bend in the direction of applying
force.  Since they bend it is easier to keep a constant amount of
force, and it is easier to vary the force when you want to do it.
It is also easier to avoid using too much force, because you'll 
feel/see there being too much bend.

Hullo.

I have been interested in locks and understanding how they work for 
the longest. However, I have much to learn and many questions to go with
that.

Forever I have heard friends say "Oh, I can 'pick' a combination lock" but
have yet to have one prove it to me. I know the little locker combination
locks supposedly can be shimmed open much the way handcuffs can be. What
about real heavy duty locks. We have an old safe in an office where I work
and to figure out the combination I had to actually remove the cover to the
tumblers and figure it out that-a-way. It is a four number combination and
I do not see how in the world a stethoscope and good hearing would help get
something like this moster open.

How does a locksmith go about opening a safe built into a walk for which the
combination is unknown?

If someone flattened off the top of the cylinder, then they're an idiot.
It doesn't make it any easier to rekey a lock, it just makes it easier
to use pins that are a little too short.  (And, as you point out, makes it
easier to pick).  As for "excessive chamfer", I've seen pins that were
rounded at the top, and even some that were pointed, so that the bottom
pins could be inserted either way.
