How Can I Pick Locks?

Learning how to pick locks is almost as much an art as it is a science. You can read all the books on how to pick locks and still not be able to pick a single lock.

The skill of picking a lock involves gaining a good feel for the lock mechanism and the technique needed to pick it. This requires practice and concentration.

The number and variety of locks in current use is staggering, yet the vast majority of locks in use are simple pin-tumbler designs which are fairly trivial to pick.

Common Lock Types

Common lock types include:

Pin-tumbler locks
Warded locks
Wafer locks
Lever locks
Dial combination locks
Disc combination locks
Push-button combination locks

Cryptology and Physical Security: Rights Amplification in Master-Keyed Mechanical Locks

This paper examines mechanical lock security from the perspective of computer science and cryptology. We focus on new and practical attacks for amplifying rights in mechanical pin tumbler locks. Given access to a single master-keyed lock and its associated key, a procedure is given that allows discovery and creation of a working master key for the system. No special skill or equipment, beyond a small number of blank keys and a metal file, is required, and the attacker need engage in no suspicious behavior at the lock's location. Countermeasures are also described that may provide limited protection under certain circumstances. We conclude with directions for research in this area and the suggestion that mechanical locks are worthy objects for study and scrutiny.

This paper is a general survey of safe and vault security from a computer science perspective, with emphasis on the metrics used to evaluate these systems and the weaknesses that cause them to fail. We examine security against forced, covert and surreptitious safe opening, focusing on the mechanical combination locks most commonly used on commercial safes in the US. Our analysis contrasts the philosophy and tools of physical security with those of information security, especially where techniques might be profitably applied across these disciplines.
