7 pin tubular locks - The type of Lock that is on all kinds of equipment, such as vending and soda machines, payphones, car/bike locks, and other equipment that we consider important to protect, is a very flawed product.
You all may remember that older Kryptonite bicycle locks can be opened with with the cap from a plastic pen. The attack works on what locksmiths call the "impressioning" principle. Tubular locks are especially vulnerable to this because all the pins are exposed, and tools that require little skill to use can be relatively unsophisticated.
These locks operate in the "Security through obscurity" principle meaning that the security of these locks is based on the fact that most people don't have access to a pick that can operate around its pins which are positioned all the way around the circumference of the cylinder plug. This makes them much harder to pick. Unless you have the right pick.
Well as the summer comes to a close and the school year well on its way,
comes drinking and having fun. Many of you will come up with the
bright idea of getting a "Vending Machine" and filling it up with your
favorite beer-verages. However most machines that you will come across will
either not come with keys or not even come with a lock. I am going to show
you how weak the 7 pin vending lock is and what type of lock you should
choose or "pick" when purchasing a lock for you machine. I will also show
you how to install a lock into a vending machine.
Since the machine I had did not come with a lock and the lock that I had did
not have a key our
friends over at
Defense
Devices gladly helped me out.
Keep in mind you should have a
license
before attempting this or even purchasing these types of products.

On with the show -
You must determine the type of lock you have on your vending machine.

This is a 7 pin lock- hence the 7 pins that are located inside of the lock.
We are going to use a 7 pin lock pick from
Defense
Devices to tackle this job.

Pin keys are in red
You will need to loosen the tightening bolt so that the pin keys can slide
flush with the cylinder tube.

Press the front of the key against something flat such the side of the
vending machine.
Do this gently

If you mess up and push the pin passed the tube- you can use the ring to
push the pins back out again.


Make sure this pin slides into the notch on the lock

Before you side the pick into the lock make sure you tighten the
tightening bolt.

Don't make it too tight but make it tight enough so that it slightly lets the pin
keys move.
Insert the pick into lock- make sure that you put it in perfectly straight.

As you insert the pick, make sure to turn it slightly to the right as you
continue to push forward into the lock.
You will notice the pin keys will move backwards as the key is inserted

Before entering the lock
After

When you reach the back of the lock you will feel the spring that you need to press
against slightly.

You don't need to use much force as you will push in and turn to the right.

Once you have picked the lock make sure you tighten the tightening bolt down
to lock the pins in place.

The lock is now in the open position
Make sure you don't adjust the pins of the pick before removing the pick.

Take note that the lock is not in the correct position.
This is another example of the lock not returned to the correct position.

Next we will show you how to add your lock back into you vending machine
This is where you would slide your lock into after setting the lock in the
open position.

The red area is where you would slide the lock "dead bolt" into.

Once you have completed this step you are now ready to lock your vending
machine.
Since writing this article - I decided to beef up the security of my lock.
If you need a secure lock -
Vanlock
was my choice for security.
This type of lock is like having a combo within a lock -- I do believe that
one lock could have about 300,000 possibilities.
Now with all this said please take note:
I-Hacked.com / Defense Devices
- would not endorse anyone taking any
product without paying for it and that carrying lock pick equipment might
get you in trouble with the law if you don't have a legitimate reason for
having it.
