for attending this first basic seminar. This session will introduce
you to door cavity lock systems and demonstrate the manifold uses
of the versatile Z-Tool. The nice thing about an online seminar
is you can visit and revisit at your own pace. It is always there
for your new hires. The second seminar covers getting the job through
final payment. The third advanced seminar covers the do's and don’ts
as well as the pitfalls to avoid while executing the opening procedures.
Lock Tool Co., Inc. has been a research and development facility
for over 20 years specializing in the how-to art of automotive entry
through step-by-step manipulation. We manufacture and supply the professional
lockout technician with an affordable, compact, up-to-date tooling
system focusing on damage-free opening methods utilizing as few high
quality, versatile tools as possible so as not to overwhelm you or
your employees. Less is best in this business.
use designs which pass the high standards expected in lockout tooling.
First, they must be damage-free to make their way into the Grand Master
Z-Tool System. Second, each tool must unlock a wide range of models. And
third, they must have the ability to unlock the wide range of vehicles with
little training beyond looking up each model in the extensive Vehicle Index
Guide. “Dig for it” openings are a thing of the past we leave to the amateurs
who tarnish the industry as a whole. Most of our tooling is made of a superior
custom made stainless rod that meets important requirements of lockout tooling.
We desire thin rods offering high tensile strength - a very difficult combination
to achieve. The golden finish on most of the stainless tools is due to a
soap like residue burned during the final tempering process. The stainless
tools with this finish will brighten quickly as the tooling is used.
manual is constantly revised. . . not only on newly introduced
models, but on ones that have already been researched and published
in previous editions. Many obsolete illustrated methods have been
upgraded or removed as new knowledge is gained or as new tooling is
introduced such as the Inverted Z-Tool and others. Please feel free
to call us to note any problems you think are obviously incorrect
with any of the methods presently being used. This is the only way
the thousands of us together can be absolutely sure we are passing
into the next model year with the past edition’s flaws fixed forever.
opening is not so much an art of manipulation as it is an art
to analyze where the manual lock button's linkage or other moving
parts are exposed to manipulation. We know all vehicles have a primary
lock linkage which starts at the manual lock button and travels
through the door cavity ending at the door latch. A second available
lock linkage travels from the key activated lock cylinder again
traveling to the door latch. This secondary lock linkage is seldom
assigned for opening newer models of the past 10-15 years which
caused Slim Jims® to become obsolete. This is due to the higher
security of modern key cylinders that prevent the secondary lock
linkage from moving without the key in the lock. The higher security
lock that prevents this linkage from being moved is often referred
to as a hard pawl key cylinder. The older low security lock is often
referred to as a lazy cam lock which will allow movement of the
lock linkage with or without a key inserted into lock. The method
to open vehicles containing the phased out lazy cam locks are viewed
at illustrated opening method #2.

Two Common Bell Cranks
System seldom assigns a Bell Crank as a target, as there are two plastic
clips involved to break or disconnect.
#1 door cavity tool used throughout the world! The simplicity
of this system would not be possible without the patented geometric
shape and many other features of the famous Z-Tool®. The greatest
advantage to having a single Z-Tool is that it does the work of over
30 other tools you would otherwise have to purchase, learn and carry.
The one tool does-it-all concept means you quickly develop a consistent
feel for what the tool is doing within the blind door cavities. Instruction
terminology also becomes second nature as your experience quickly
grows due to constant use of the same tool over and over again.
Sister Inverted Z-Tool
Probing Tool: You will learn through experience that the geometric
shape of Z-Tool® is ideal for probing the door cavity for illusive
targets. You will also learn that either the long or short end can
be used to move bell crank and most any mechanisms with or without
the use of the hooks. If you contact nothing while probing for the
illustrated lock mechanism, do not become discouraged, as it only
takes slight adjustments to make contact with the intended target.
Always keep your eye on the manual lock button while probing as
most will slightly move when contact is made with any part of the
lock system. Try a second time, but simply pull the exposed
end (handle) a little away from the window glass to gain a wider angle
within the door's cavity, thus allowing the probing end to reach the
Mini Box Hook
Mini Box Hooks: The numerous situations involving obstructions within
the door cavity are most often overcome due to features designed into
both the versatile Z-Tool® and the Inverted Z-Tool®. One such feature
is the Mini Box Hooks for slipping past or around obstructions.
The hooks are made small and then milled out at the inside to allow
a strong positive grip onto the target. Once the target has been grasped,
this milling process will keep the tool from slipping off the target
at the moment the required pressure is applied to move the lock system
to its opened position. The boxed edges should be filed periodically
to keep them sharp as you will find they are utilized constantly.
present obstacles within the door cavity, such as a variety of anti-theft
window guards, linkage guards and/or shields, and center walls. Centered
walled models present the greatest of difficulty as they offer little
to no exposure to manipulation. In the cases of no exposures, non-door
cavity tooling is assigned. Non-door cavity tooling and others are discussed
at the advanced classes.
Depth Guides: The numbers #1, #2, and #3 are stamped along
the shafts of both Z-Tool® and the Inverted Z-Tool®. Some instructions
require you to pinch the shaft at the assigned # while inserting
to the desired depth. Desired depth is achieved when your pinched
fingers match the outside weatherstripping located at the base
of the window. Pinching the assigned depth guide will allow you to
maintain the desired depth while probing for illusive targets without
constantly keeping an eye on your depth setting. Any opening which
needs the extra help of depth guide usage should alert you to the
fact that this model can be tough to open and requires your complete
attention to instruction detail. Slow down, carefully review the procedure
starting at the Vehicle Index Guide and then onto the assigned
opening method. When a new instruction page is successfully learned,
make some notes above the illustrations. Doing so will jog your memory
the next time you are advised to use that particular method.
Depth Guide Blow Up View
good example of depth guide use is at method 21. Method 21 applies to
the new style General Motors lock latch introduced in 1991. It is assigned
to those models which are heavily guarded throughout all four door cavities.
However, there is available to manipulation a one inch linkage exposure
at the front passenger door latch. Learn this advanced method and you will
be one of the few who can open the many GM models containing this well guarded
Place proper tool end in alignment with matching drawing. Pinch the
shaft firmly and bend to actual size and shape. Double check and reshape
on the inside back cover of the manual is an actual size bend
chart. A small percentage of opening methods will first direct you
to shape the Z-Tool®. Simply lay the tool in alignment with the bend
chart and bend the stainless steel shaft of Z-Tool® to conform to
one of three (3) specific configurations. Again, this saves 3 more
tools you would otherwise have to buy, learn and carry. The bend chart
shapes (A, B and C) are very accurate, since the configurations are
drawn actual size. Other door cavity specialty tools requiring specific
shapes will lose their original factory-set shape due to use or abuse.
In such cases, corrections are hit-and-miss, but with Z-Tool®, you
can shape and reshape, over and over, with this handy actual size
your tools to their original shape after every opening, particularly
after opening models that instruct you to use the bend chart located on
the inside back cover. It will then be ready for the next lockout call.
Creating a flawless straight shaft is not necessary. A long history of statistics
has shown the bend chart will not cause the shaft to break. We know of tools
that have lasted as many as 4500 openings with the same Z-Tool®, as all
were logged by the same user.
of our long time customers order at least one extra Z-tool and an inverted
Z-tool. They put the bend “A” into the extra Z-Tool as “A” is far more needed
then the B&C setting. If the tool is lost they have a back up while the
new replacement arrives. Z-Tool alone opens 65% off all openings. If lost,
your ability to continue lockout calls are drastically hampered.
