Need to get into a building? Start a police car? Borrow a bulldozer? Go to a restricted elevator floor? It is pretty easy with the right tools and sometimes a bit of practice.
Knowing what those tools even are is half the battle. This guide attempts to solve that for you for for free.
Actually obtaining these tools is non-trivial but -all- of them can be obtained legally by licensed locksmiths. Becoming a licensed locksmith in most states is fairly easy, and in most states only requires paperwork.
Or you can just get almost all of it from China.
This is only for use by locksmiths and penetration testers.
For everyone else: Use this to educate yourself and others on why using keyed-alike systems is generally a stupid idea.
Using this information to commit a crime is an even stupider idea.
Pay attention to local laws. Many security tools are not legal in many states.
When companies wish to purchase a large number of something, such as a filing cabinent or a fleet of police cruiser, they often opt to save money by using a common mass produced key.
If you happen to know the key model number and the specific use cases you could buy most of them on Amazon.
Keys are ordered by roughly by how commonly used they are.

- Amazon, and Ebay have basically everything. Dhgate generally has the rest.
