	The No. 2 cylinder is a [[pin-tumbler]] lock with four pin stacks and no [[security pin]]s. The cylinder typically uses the [[M1]] [[Key#Types_of_Keys\|key profile]] but may use other profiles, as well. The standard No. 2 can be opened in both directions but the "commercial" series body restricts opening to clockwise rotation. The No. 2 is not a [[key retaining]] padlock.

The '''No. 2''' is a [[pin-tumbler]] [[padlock]] made by [[Master Lock]]. The No. 2 uses a laminated brass padlock body with an internal key-in-knob-style [[cylinder]]. The inner cylinder uses four pin stacks and does not use any [[security pin]]s.

The No. 2 is a common low security padlocks used in the United States.

== Principles of operation ==

The No. 2 cylinder is a [[pin-tumbler]] lock with four pin stacks and no [[security pin]]s. The cylinder typically uses the [[M1]] [[Key#Types_of_Keys|key profile]] but may use other profiles, as well. The standard No. 2 can be opened in both directions but the "commercial" series body restricts opening to clockwise rotation. The No. 2 is not a [[key retaining]] padlock.

== Disassembly instructions ==

The No. 2 cannot be disassembled non-destructively. To disassemble it the rivets that hold the laminated body together must be removed and each layer removed individually. The inner cylinder itself can be disassembled in the same manner as a traditional pin-tumbler lock:

{{Pin-tumbler standard disassembly}}

'''Notes'''
* The No. 2 cylinder requires a small diameter plug follower.
* The No. 2 plug is retained by a crimp, rather than a C-clip or [[cam]]. Above are the generic pin-tumbler disassembly instructions.

== Vulnerabilities ==

The No. 2 is vulnerable to a wide range of attacks. The reduced pin tumbler count and poor manufacturing tolerances makes it an easy lock to pick. It's commonly given to [[locksport]] beginners as a "confidence lock"; a lock that is easy to open and inspires you to continue picking. The No. 2 may be vulnerable to one or more of the following:

* [[Lockpicking]]
* [[Key bumping]]
* [[Impressioning]]
* [[Decoding]]
* [[Bypass]]
* [[Destructive entry]]
