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.
Update:
Defense
Devices has granted I-Hacked a discount when purchasing tools.
On with the show -
We are going to use a 7 pin lock pick from
Defense
Devices to tackle this job.
You will need to loosen the tightening bolt so that the pin keys can slide
flush with the cylinder tube.
Before you side the pick into the lock make sure you tighten the
tightening bolt.
Insert the pick into lock- make sure that you put it in perfectly straight.
You will notice the pin keys will move backwards as the key is inserted
Make sure you don't adjust the pins of the pick before removing the pick.
Since writing this article - I decided to beef up the security of my lock. 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.
