Introduction

Well, as they say, starting off is the hardest part. This applies to
many things as well as the topic we are about to discuss this evening, or
whenever the hell you are reading this. When I first got interested in
lockpicking, it was difficult for me to find any sort of phile that
explained ANYTHING at all about it. I saw a few here and there and decided
that if I could compile a large phile made of many smaller philes and
several peoples assorted research, (including my own) I could get one hell
of an interesting little do-dad for all those aspiring little thieves out
there. So here it is! But, enough of this Bull-shit.....let's get to
it.....

Basic Picking
--------------
In the following, you will see the instruments used for picking in TEXT
form about as good as they can get.
2) KNOW HOW LOCK WORKS - This is very easy. It works sorta like an
engine, with the tumblers acting like the
pistons. (They move up and down)
3) CORRECT TOOLS - You can either make them or buy them. Buying is
much better. (A place to purchase lockpicks from
through mail order is listed at the end of this
article.)
An entry lock is a front door lock, or some sort of lock that protects
what's on the other side. These are usually 5 tumbler locks, and can be
picked with some sort of ease. Go to your local K-Mart and get an El-Chepo
entry lock and give yourself a blue dot special discount. (Either 5-finger
or price reduction.) (THIS MEANS STEAL IT DUMMY!!) Once you have this, then
take the fucker apart. This may/is easier said then done. All you will need
when you are down is the part that the key goes into. After getting that
and looking it over, you will find a cap type thing on the top of the lock.
VERY CAREFULLY TAKE THAT OFF!!! If you slip and open it too fast, the
springs will go flying into a void and never be found again. The figure for
the lock is figure 4.
Once the cover is off, dump 4 of the spring and tumblers into a
holeless baggie (Ziplock preferred). Stick the cap back on and you are
ready to use the 1 tumbler lock. This is very easy to pick, that is why
you are starting with it.
Pickings
--------
Now you are ready to pick, but what? NO PICKS? Looks like you are
screwed unless you get some quick. If you are going to make them, then get
some blue spring steel and a grinder. The final product mustbe about .025x
.125 flat. If you already have your picks, then read on!
Take your one (1) tumbler lock and the feeler pick (fig. 1), and your
tension wrench (fig. 3). Hold the lock in your other habd (ie. if you are
righty then hold it in your left, and vice versa) adn stick the tension
wrench into the bottom part, so that it doesn't obstruct the feeler pick as
it moves in and out. Now turn the tension wrench downward (or whatever way
will open your lock but usually clockwise) and insert your feeler pick. You
shoudn't have to stick it in far because you are only using 1 tumbler, adn
can probably see it where you are looking. Now gently push up on the
tumbler, and the lock should open. If this fails to happen, then let loose
on the wrench and try again. If you still can't do this, then give up, YOU
ARE A LOSER IN LIFE!!! If you did open your lock, then CONGRATS!!!
After you have picked your lock, then try it again and again and again
so that you get the feel of how much pressure to put on the wrench and the
tumbler. When you think you hve an idea of what you are doing, open up the
cap (CAREFULLY!) and stick in another tumbler (both of them) adn the
spring. You should now have two tumblers installed. Now try to pick this
one. Should be a little harder, but no huge difference. If it doesn't
happen all at once, then try again. If you still can't do it, then this
time you are NOT a loser in life, just someone who WILL have no future.
Once you are done with your 2 tumbler lock, then stick in three, then
4 and then 5 tumblers. The more there are, the harder the lock will be to
pick. In one day, I got up to 4 tumblers, 5 is tricky. For less tumblered
locks, a raking pick is good to use (fig. 5).
FIGS. 1-5:

The end part there goes up smoothly to a rounded end of some chicks tits.
In the locks, the tumblers are different sizes (the ridges in the key
should have told you that) so that is would be stupid to try and show all
of the different lengths. The spring in half the size of a pen spring.

This pick is just a varation of the feeler pick, 'cept that it has
ridges that move the tumblers up and down fast.
Well, that's about it. Happy Picking.

+==========================================+
+ BE A LOCKPICK, GET INTO PADLOCKS +
+ "HOW TO CRACK A PADLOCK" +
+==========================================+
I must attribute this message/file to reading I have done from another
files about this, and some methods that I have made up on my own.
This method has been only assured with "Master" padlocks. They are a
very common padlock.. This might only work on those, but who knows..
First, pull the lock down, not so much as that it is impossible to
turn, but just enough to be able to do the following: Turn the knob around
clockwise (to the right) until you feel a small, small resistance which
will last 2-3 numbers on the dial long. You might try doing this a few
times to find the exact number that it does this on, and not to be
mistaken with another. Now, add 5 to the number you have gotten. Guess
what? You have the first number in the combonation!
There are a few mehods to get the next number. I will tell you both, one
method, is very quick, but not always 100% reliable. The other is very
difficult.
QUICK METHOD: This method will get the last two numbers in the
combination in one step.
--First, turn right and stop on the first number you got. Then, turn
left and stop on the first number again. Continue turning to the left to
the next marked number. This means that the dial goes by five, and if your
first number is 18, go to the 20.. Then turn to the dial to the right
again, while pulling down on the lock (as hard as you pull to unlock it if
you have the right combo), and keep turning to the right until you get to
the 2nd number you've tried. If it doesn't unlock, go on to the next marked
number on the dial. (For instance, you're first number is 18, you tried 20
past right, it doesn't work, then try 25.) Keep doing this until eventually
you unlock it, or it doesn't work. The most times that you would have to do
this is about 8.
HARD, BUT NEVER FAILS METHOD: As in above, turn right to your first
number, and then turn left until you get your first number again. Begin
pulling down on the lock again, and trying to feel for a little resistance.
If it is very stiff, you probably have the second number. If it is weak,
then continue turning. You should try 2 or 3 times to make sure you get the
same results. After you think you've got the second number, turn back to
the right, while pulling down on the lock between tries of oh, say every 3
numbers, and eventually, CLICK, it will open.
//=DISCLAIMER: I am not held responsible for the use of this
information. This is for, let's say, basic knowledge... Let's say, if you
ever forget your combonation, or it is very important you get into another
lock.

Miscellaneous Locks

Introduction

Some of you who are a bit more experiance in BBsing and the type of
stuff that go along with it (ie, phreaking/hacking), may have wondered what
a phellow such as Agent Bioc 003 has to do with a phile about locks. Very
little actually, but when I was reading over his manuals again, I though it
would be a good idea to include that little segment concerning phone locks
in this tutorial. While they may not be used much anymore, it is not hard
to remember how to get around one of these locks, if such a time arises.
See here.....

DIAL LOCKS
A commonly used lock is the safety chain. Y'know, the one that you
slide into the little slot along the back of your door. Well I, as well as
other people have come to the conclusion that this type of lock protects
you and your valuables from intruders/burglers about as much as tin foil
does! While the simple method of breaking through such a pitiful barrier is
to take your shoulder AND SMASH INTO THE DOOR AS HARD AS YOU CAN works
well, so do bolt cutters. I will try to explain to you how to get past one
of these locks quietly. After all, isn't the whole idea of lockpicking to
be as quiet as is humanly possible?
First, you will need about 4 tacks, some elastic bands, and some
common sense.
To defeat a safety chain lock where the door is unlocked but the chain
prevents you from stealing some valuables, simply take an rubber band and
somehow tie or stretch one end of the band over the knob end of the safety
chain. By knob end I mean the end you would take (if you were on the other
side of the door) and slide into the slot on the back of the door.
Next, take the other end of the rubber band and a thumb tack and,
reaching around the back or the door as far as you can, stick the thumb
tack into the back of the door as hard as you can with the rubber band
rapped around or somehow affixed to the tack. Then slowly close the door.
The rubber band on the back will pull the chain out of the slot for you.
You can then open the door, remove the tack, and steal stuff. (Fig. 1)

Well, so far, most of what you have been reading has been things that I
have picked up in a few scattered philes and people. Now I will begin the
actual tutorial. This includes descriptions of all kinds of locks, most
still being used today from the locks on your screen door, to the lock on
your car.
----------
- PART 1 - BASIC RULES AND PRINCIPLES
----------
The main key in bypassing any lock, is to know how the lock works and
its design. For example. Many banks use what is called a partition lock
to lock a swinging door.
---------------------
- -
- === -
- Knob --> = = - Partition Lock
- === -
- -
--------------------
When an irate customer comes barging into the bank wanting attention
NOW, they may go up to the lock, and begin jerking, pulling, whatever on
the little brass knob expecting to open the gate. But nada happens.. This
is because the know is a phoney.. It is there with only one purpose, to
fool the customer. The real way to get in is to use your finger tips and
push up on the false bottom. This opens the gate. So the "key" here was
to know how the lock worked.. Get it?
----------
- PART 2 - WARDED LOCKS
----------
Well, now that we have gone through the basic principles, let's take a
look at the easiest type of lock. The Warded Lock. In warded locks the
key, when inserted and turned, merely engages a locking bolt mounted in the
case and slides it to the locked or unlocked position. In addition, the
key may also lift or disengage a bolt retaining lever or spring; or ot may
act on the bolt via an intermediary lever.

Were the patterns were cut ----
This type of lock offers the bare minimum in amount of security since
almost any object resembling the key will open the lock. The next step up
comes when a locksmith inserts teeth called wards into the keyway or the
turning path of the keybit, the end of the key that is inserted into the
lock. A simple example is to cut the keyway with a tooth extending halfway
into the keyway to block access. The lockmaker then cuts notches in the
key where the ward would block the path. Example:

They are in obstruction of the wards. It simply passes over
keyway. them.
These locks eventually involed many wards within the lock, resulting
in large but very figurative keys. A locksmith would usually create teh
lock first including all of its wards. Then take a key with a rough out-
line of the wards in the lock already on it. He would then put the "blade"
of the key in the center of a candle flame, coating it with soot. Then the
key was inserted into the lock, turned, and removed. The markes where the
wards were left tiny scratches which were then filed down. Since many
people can do this simple method, security was nil. Eventually the famed
"Skeleton Key" was created around this time for this type of lock which was
usually an "L" shaped tool designed to bypass many different types of
warded locks. You may/will find these types of locks on many 1910-1940
homes, chest, and other assorted apllication where security was either not
highly required or known. Another simple security messure was to have a
small peg at the end of the inside of a keyhole. Thus the pipe key, with
its hallow end was made. I believe that some police handcuffs used
to/still do use this method. Those stupid little locks you see on luggage
etc. are usually of the warded type. The only problem these little suckers
pose is that since their keyways are so small, it makes it difficult to
find a pick to fit into the hole. Careful though, because these locks may
also be lever tumblers which are quite different but look the same from tht
outside. A look at the key can usually help you tell which is which..
Many padlocks are warded as well. But they are usually bottom of the
line models. If the coer can be rotated by inserting a straight tool it is
a warded lock; if not, it is a disc or pin tumbler.
B L T
Begin you BLT (Bypass Lock Technique) on warded locks. When trying to
pick one of these locks, you are trying to 1)avoid all wards 2) contact and
swing the bolt with enough strength without breaking the pick and getting
you ROYALLY pissed off. You would be best to purchase a bunch or skeleton
keys from a manufacturer for these locks.. They usually come in sets of 4-
6 and are your only alturnative to making you own skeleton keys with the
soot method using blanks.. Remember to becareful if you decide to cut your
own keys.. If you use the same key for different locks, you MIGHT end up
putting too many wards into one key thus weakening the key and it could
become very uneffective, especially when it breaks off in the lock.
Now, when picking a lock, you must remember also the treatment to give
a lockpick/skeleton key. DO NOT EVER use the slam-bang method like you
would with your house key. Insert it slowly, feeling for obstructions
until it bottoms, then turn it slowly and feel for the notch cut into the
locking bolt that the key blade must contact. If you hit a solid
resistance, that you have most likey hit a ward, if it is more springy
thenyou have probably hit a bolt retaining spring which must also be
lifted. Be sure to always carry the proper tools.. Otherwise, a simple
warded lock on an old door may stop you dead in your tracks.
Warded padlocks are very common and are the perfect learning and
practicing tool for beginners. You should definatly buy ATLEAST one to
practice with and possibly even to attempt the soot method with.. It is
good to get more than one so that you can see what different brands of
locks look like inside or how to pick another warded padlock once you have
conquered another.
To do this BLT, it is usually required that you pull on the shackle of
the padlock to make a tension. If you are having problems, you might want
to try varying the amount of tension you apply when trying to pick the
lock.
That just about covers warded locks and related BLT. You should begin
practicing on these locks as soon as possible to help boost your ego of
actually opening a lock and not to mention, a thief that gets stopped by a
warded lock looks like a complete moron. 90% of this beginning lesson
should be preparation, getting the right tools, and beginning to understand
locks. The other 10% should be practice.
This completes this section and your education of Basic Principles and
Warded Locks. Look for:

HOW TO DO ITS:

THE KEY IS A SMALL CIRCULAR TUBE LIKE KEY WITH A LITTLE NOTCH
AT THE END OF THE KEY, WITH FIVE SMALL DITCHES IN THE TUBE.
WHEN ALL THE PINS ARE ARRANGED SO THAT THE LOCK TURNS, PRESTO!!!
SOME HAVE SEVEN PINS....
SO TO MAKE A KEY THAT WORKS WITH 5 PIN BIKE LOCKS AND ET. AL.
MAKING THE KEY IS VERY HARD...YOU HAVE TO MAKE A KEY, EVERYTIME YOU USE IT,
ONCE! THIS IS A BITCH. THE PARTS AREN'T THE EASIEST TO FIND EITHER.
FIND 5 SPRING STEEL NEEDLES THICK ENOUGH FOR STRENGTH, BUT THIN ENOUGH TO
FIT INTO THE SIDES OF THE LOCKS. GET A TUBE THAT FITS THE LOCK PERFECTLY.
YOU CAN KEEP THE TUBE FOREVER. TAPE THE SPRING STEEL NEEDLES ONTO THE
PIPE. LET THE SPRINGS STICK OUT ABOUT 5 mm OUT OF THE PIPE. BUT MAKE SURE
NONE OF THE SPRINGS ARE LAYED OUT EVENLY. NOW, INSERT IT INTO THE LOCK.
GIVE IT A RAPID IN AND OUT MOTION. GET A SURGICAL SPRING NEEDLE FROM YOUR
BIOLOGY LABORATORY AND USE THAT TO ROTATE THE LOCK AS YOU JIGGLE IT IN AND
OUT. I HAD A HELL OF A HARD TIME PICKING OPEN A KRYPTONITE LOCK. I LOST
MY KEYS TO MY BIKE AND IT WAS LOCKED TO A POLE. IT TOOK ME ABOUT 20
MINUTES. I HAD SUCCESSFULLY OPENED ONLY 5 OF THESE TYPES OF LOCKS, ONE OF
THEM BEING A SEVEN PIN. IT IS VERY FRUSTRATING AND HARD. BUT WORK ON IT.

- PART 3 - Disc Tumbler Locks
----------
To start off, a tumbler lock is any part of the lock that is directly
moved by the key and also has an unlocking function. So, the tumbler in
the lock we are about to discuss is a lot like a disk, with a small
rectangular looking slot cut into....about the center.

| | | |
| | |<------------ Key Slot
| | | |
| |_| | (This is BASICALLY what one
| | looks like. Only the edges
|_ _| and corners are slightly more
|____| rounded.)
The trick is that the position of the slot can be varied, depending
where the maker wants to put the key slot. It can be up slightly, further
down slightly, (there are set increments, but there is no REAL reason to
discuss them) but the dimentions of the slot itself never change. Now
imagine that you take 5 of these disks (approx. nickel sized) and thread
them onto a typical disc-tumbler key. (The key looks like your normal,
average house key, only smaller. Keys to outer screen doors arean
example.) Make sure that the disk you are imagining, are resting in the
absolute bottom of the "V" cut on your key. (You can do this, if you like,
with 5 pieces of cardboard to help you understand the concept.)

(HEY! It ain't that easy drawing a key in text so give me a break ok??)
So you can see that the disks are all the same height. This is how it
should be with the varied key slots through the cardboard to adjust to the
different depths of the "V" cuts.

The slots in the plug hold the tumblers in place parallel to each
other but allow each tumbler to move individualy. The disks protrude
outward from the slots with a constant outward pressure being exerted upon
the disk by little springs under the spring finger of each tumbler.

Notice the 2 grooves that are 180 degrees apart. When the plug is
inserted, the disks coming out of the plug are lined up with these grooves.
This is what holds the plug from turning thus releasing the lock. Once a
correct "key" is found that will turn the mechinism inside the plug, the
disk tumblers will slide down into the plug, then allowing the plug to turn
within the cylinder, thus opening your neighbor's...er....your door...
The trick is to get all the tumblers at their varied hights, lined up
so that they will all go into the plug and not impeade rotation. So if you
had a disk tumbler lock that was loaded with all #3 depth disks, and a key
with all #3 height "V" cuts, all the disk would go into the plug and you
would be able to open the lock. Unfortuanly, such simple designs are never
found, otherwise a straight wire could open the lock. So the lockmakers
make it so all of the disk are at different depths, making it that much
harder to align all of the disks at the same time. Rememeber, even 1
protruding disk will keep the lock locked.
Another type of disc tumbler lock is one that has two independent
banks of tumblers that are 180 degrees apart. They fairly normal when you
see them through the keyway,but they are really different because they move
independently. They do tend to look like a staircase in the keyway. The
way to tell for sure is by using a feeler or straight pick. Begin to
manipulate one side. If both sides then move, you know that you are
dealing with the normal variety. But if only one side moves, not both, you
know you are dealing with independent banks of disk tumblers.
Most if not all disk tumbler locks have what is called a plug
retainer. This keeps the plug from being taken out end-wise from the
cylinder. They range from cams screwed in at the far end, to snap rings,
to being welded together at the factory. The most common is a disc
retainer. This is simply an extra disk added to the end of the plug that
does not move when the key is used. Some locks have a small hole in the
lock face that can be used to defeat the disk retainer when th elock is
unlocked. By using a cylinder retainer shim tool (Figure 5) you can push
the disk retainer into the plug and remove the plug from the cylinder.

Since most plugs have a "shoulder" on them that prevents someone from
pushing them into the cylinder, they can not be accessed that way either.
Basic Appearance
----------------
Most of the disk tumbler keys look like your house key (pin tumbler
lock) but are a little smaller, about 1/4 or an inch shorter.
Picking
-------
Okay, you've had alot of backround shit throw at you, now let's put it
to work and try to pick some locks. I recommend maybe trying your own
locks around the house if you have any. In part 4, I'll tell you all the
stuff you'll need to get started on mounting some prctice locks if you
choose to do so.
Once you have found a lock to try, or have mounted a practice lock in
wood and put it in a vise, get a tension wrench (Figure 6). Insert the
tension wrench into the lock making sure that you don't block the keyway
cause the raking tool in going in next (Figure 7).

After you insert the tension wrench into the lock, apply a little
turning pressure in the direction that the lock nomally turns in. Do this
until the disk bind, or cause resistance. Now insert the rake into the lock
under all of the tumblers. (Note: Some locks have no backing so be
careful not to stick the pick into the space behind the tumblers.)
Now, check to see if the rake moves smoothly in and out, touching all
of the tumblers. If not, the rake may be too high. Grip is also a factor.
Your best bet would be to hold the pick like a pencil, and let it pivot at
the point where the fingers grab it. If this is not comfortable, try
holding in a way that is better for you. Tension is just as important.
Remember to apply CONSTANT tension, but not too little, or too much. This
you will just have to determine mostly with practice. Too much tension
prevents the tumblers from moving, while to little gets you just as far.
If you are having trouble with the first method, here are some things
you can try. Try varing the tension, but don't let off totally.
Sometimes, when you ease tension while doing a stroke, the lock pops open.
Remeber, too much tension can also cause your pick to bend instead of
scrub, so unless you like spending money on new picks, go easy. Also,
sometimes a figure eight motion works good. To try this, keep the wrist
loose, and let your fingers move the pick. One last technique you could
try would be the "ripping" technique. This is when you carefully insert
the pick into the lock without touching any tumblers, and then ripping it
out in one very fasy stroke. If you have opened the lock, CONGRATS! Do it
again..and again..and again.. If not, make sure you are trying to turn the
lock in the right direction. You can also check the key profile. If the
key is fairly straight, with few deep "v" cuts, it is easier to open than a
lock that has a key with deep "v" cuts (Figure 9).

- PART 4 - Practice Locks and Some Dos and Don'ts
----------
Try to get fairly cheap ones because cheaper usually means easier to
pick. You should be able to pick most up at a local store, except maybe
the warded mortise lock in which case you may want to go to some second-
hand store, chances are you'll get it cheaper there anyhow.
What you basically want to do, is mount the lock into a piece of wood
as you would mount it into a door. Then clamp the wood in a vise. Or you
could make a sort of cabinet with all the locks in one place and mount the
cabinet on you wall where you can practice. Either way is fine. Just make
sure you have SOME PLACE to practice. A little hint is to put the mounted
lock(s), if possible, in a place where you walk often. That way you can
practice every time you walk by or atleast you won't totally forget to
practice a little.
Remeber to practice alot on the pin tumblers once you know how to pick
them (in next phile) because they are the most common. Also, don't forget
that when you are picking to sometimes practice with a flashlight because
when you are out in the "field", the owner of the house will most likely
not be there holding a flashlight for you. Try holding the flashlight in
your mouth or even taping it to your arm. If you want, you can also try
velcro. Two fifteen minute practice sessions a day should get you well on
your way.
If you have looked in catalogs for lockpicks, I'm sure you have seen
those "all in one" types. Where you get 8 picks inside a pen or something.
Well, take a little advice and DO NOT buy one of these. Why? Simple.
When you are lockpicking, you will often need to change the type of pick
you are using. So if you need two hands to unscrew the old pick, and put
on a new one, whixh hand is holding the tension wrench? None. So you lose
tension and have to start all over again. Gee, isn't that fun. I would
suggest buying one of those leather case tools. They may be more
expensive, but they are worth it. Not to mention, the companies that make
those "pen picks" seem to enjoy giving us 8 picks with 5 of them being of a
type you will never use in YOUR lifetime. So stick to the kits that come
in cases. These are generally better quality and easier to access cause
you can just drape an open case across your knee when picking.
Next, figure out what type of lock it is. A stamped metal plate with
a keyway cut into it is usually a warded lock, or a lever tumbler lock
(lever tumblers will be in the next phile.) The circulaer shaped locks,
like the ones on the door to your house, are usually pin tumbler, disc
tumbler, or wafer tumbler locks (Schlage). On padlocks especially, if the
core rotates, this could mean a warded lock. It is a lever tumbler lock if
the rotating core has a slot cut in the side of it's retainer. If the core
doesn't move, it is a pin tumbler.

Next, check the keyway for foreign objects. A little trick some
burglers use is to put broken toothpicks in the key way. This slows down a
homeowner who could surprise an unalert burgler.
Also, make sure that you can see the tumblers. If not, they could be
jammed up inside the cylinder. Something else that you may sometimes
notice is that there are very few tumblers. This is because some shity
locksmith put in only a few tumblers, this making the lock easier to pick.
Also, make sure you know what type of lock it is. It may not be what you
think.
Also, check for a brand name if visable. Certain brands like, CORBIN
or RUSSWIN use or have installed slightly different parts making the lock
a little harded to pick, sometimes (i.e. mushroom pins)
Next, insert the tension wrench into the plug and try to ratate it.
The more it rotates, the more play is in the lock, meaning it's easier to
pick. While you are doing this, try to figure out which way the plug
turns. This is VERY important. If you apply tension in the wrong
direction whiel picking a lock, you will never open it. You can tell the
difference by the way the plug stops. If you feel an abrupt, solid stop,
that is the WRONG way. If you feel a slow increase in friction to a stop,
that is usually the way to turn it.
Cleaning the lock is also very important. Well, not VERY important,
but it is good to know. A hint if the lock is in bad condidtion is if you
smell some kind of lubricant. Chancea are that the lock is not in godd
shape and the owner tried to get it to work better by shooting some WD-40
into it, which by the way is bad for locks cause it leaves a residue. Use
lighter fluid to clean a lock. Gasoline and LPS-1 are also BAD to use
cause of the residue left after evaporation. WARNING: Cleaning the lock
with lighter fluid or naptha (another cleaning agent) leaves a smell. This
will be left behind after you have gone for the homeowner or whomever to
smell and shows that someone was fideling with the lock. Flush clean
twice, using a straight tool to work the tumblers betwwen each washing.
Then blow dry. You could try those gases in a can from cetain chemical
supply house also to blow the lock dry. The purpose is to float away any
dirt when cleaning and drying the lock.
Now that the lock is clean, if it wasn't already you are ready to pick
it. Some people like lubricant in a lock, other don't. It is your choice,
but if you do, a short squirt of powdered graphite is you best bet to use.
Also remeber to look under flower pots, rocks, etc for keys before
attempting to open a lock. Just think where you might hide something, and
look there.
Try to get into the routine of surveying the lock in the ways just
described. If you get in a habit of it, you may not overlook something
obvious when it happens. It will also help you in general to open locks.
So until then,
happy trails,
and remeber not to get the foreskin caught in the zipper.

Introduction
------------
Within this brand new, (or real old phile, depending on when you
get/read it) we're gonna discuss part 5, Lever Tumbler Locks. Part 6,
which will involve Pin Tumbler Locks, like the locks used in car doors, was
supposed to be here, but was pushed back slightly due to schedule changes.
It WILL be in the next phile of the series however..
Since I won't be compiling any other works into this chapter, it will
be a bit smaller than the previous philes, but hopefully just as good. If
you missed the first two, they can be had from Hellfire, as well as any
other SANctuary philes. We'll start off with a little introduction to
Lever Locks... A word of warning. If you haven't read the first two
philes, I would recommend you reading them before this one, or at least
reading them sometime in the near future. I have written these philes in a
way so that people who have already read my older philes, do not have to
deal with re-reading things they already know.

- PART 5 - Lever Tumbler Locks
----------
Uses
----
A place where you WILL see this lock would be safety deposit boxes.
But, since it is incredibly hard to pick when it is being used as a lock on
a safety deposit box, most locksmith's use a "nose puller" to open the
lock. This involves screwing a sheet metal screw into the key way of the
box and pulling the door off the box. Some places where you will also find
lever locks would be older office equipment, chests, cabinets, luggage
locks, etc. Some early mortise locks are lever locks also.
Keyway
------
Lever locks have a unique look to them. They are a slot cut into the
face of a metal cylinder with a matching slot on the collar or the lock
cylinder.

The Keys
--------
The keys that are used to open these locks are often called flat keys.
Why? Because that is exactly what they are. They are flat stamped keys
with no side warding cuts whatsoever. The one cut they have, called the
throat cut, is near the bow of the key. The key has varying rectangular
depths near the tip that move the retainers to their varied height in the
lock.
As stated before, lever locks are much like disc tumbler locks. So,
as in disc locks, the disc is the varying heights mechanisms while in lever
locks it is the lever mechanism. Here the lever is moved to varying
heights against a spring by a key, and then the bolt stump is free to be
pushed through the aligned slots in the interior of levers from one cutout
area to another.
In a lever lock, the key engages the bolt just as it would disks in
disc lock. But in a lever lock, the key elevates the tumblers by rotation
not my being shoved into a lock like a disc tumbler (figures 2 &3).

Notice the shape of the key end. By the way, with this type of lock,
the key end will always consist of rectangular cuts and no wedge profiles.
You would insert the key into the lock on its side so that it lies flat.
The small area marked with a plus (figure 3. The plus means nothing, it is
only a marker.) is where the key would be inserted into. (The lever,
figure 3, is inside the lock.) As you turn the key, you would lift up the
lever bar just as you would be lifting up a disk.
The cylinder itself holds the key at the proper height in relationship
to the levers and rotates the key on an axis. The tumblers will come in
stacks of two, three, all the way up to fifteen. Each tumbler having a
common pivot point and an individual spring. So when the key reaches is
TDC (top dead center) it lifts each tumbler to its correct height based on
the levels and depths of each key bitting as well as the levels of the
gates (the area cutout on the bottom of the lever). If you have been
following closely, you should be able to realize that this type of lock is
much the same as a disc but uses retangular cuts and levers instead of
wedge cuts and discs.
One small note to remember is that all lever locks of simple design
are dead locks.

The part of the wrench marked "A" is the part that changes. It's
length may differ from wrench to wrench depending upon the lock it is meant
to pick. The "A" dimension is the correct size if the wrench corresponds
to the length of the key from cylinder cut to tip. If the "A" dimension is
any longer than that, you will not get proper pick manipulation. You can
usually buy a set somehow which generally will have four or five different
sizes. You CAN try making your own, but I don't recommend it. If you
absolutely must make your own, try bending one from .040 music wire and
then grinding each side flat. As for lifters, your normal set that works
disc and pin tumblers will also work for levers.
WARNING: do not over lift any tumbler, because this will mean that you
will have to start over. This is a very common, and pain in the butt
mistake. Some locks even have a little thing inside of them that detects
over lifting, and will permanently lock the lock if triggered.
After you have lifted the first tumbler, the one furthest back,
proceed to the next one, going from back to front. You may notice a slight
lessening in tension here, or may not. The feel of the tumblers entering
their gates will feel less and less as you go. After all the tumblers are
lined up, the bolt moves, unlocking the lock.
Here is something that you should watch out for. In some locks, they
make the cuts in the tumblers at extreme degrees. Meaning that in one
tumbler they will cut it as deep as possible, while in the next, they will
cut it as shallow as possible. This, by the way, is not possible with disk
or pin tumbler locks. This is very good security because it becomes very
difficult to lift one tumbler high enough without touching or causing
misalignment with the other tumbler. So, one thing to expect with some
lever tumbler locks is a high-low-high-low-high etc. combination on good
locks.
In a closing note for lever locks, let me just add that often you will
come to what appears to be a small lever lock which is in actuality, merely
a warded lock with a spring retainer that must be lifted before the bolt
can be moved. Now while the amount of lifting you do to a retainer is not
critical, for a lever lock it would be.
