I will get round to putting something here at some point soon... got literally hundreds of locks sat here just waiting to be photographed, taken apart, researched, and uploaded... ;-)

The '''M4''' (or '''M<sub>4</sub>''') is a [[UL 437]]-rated [[Pin_tumbler|pin-tumbler]] lock made by [[Medeco]]. The pin tumblers use [[axial rotation]] to interface with a [[sidebar]] located at 3 o'clock in the [[plug]]. It also features four spring biased [[Side_pin|side pins]] that restrict movement of the sidebar until properly positioned. One of the side pins is lifted by the Shuttle Pin movable element in the key. The M4 is easily identified by the "M<sub>4</sub>" logo to the left of the keyway.

It is called the M4 because it is the forth generation of Medeco's axial rotation system, following the [[Medeco Original]], [[Medeco Biaxial]], and [[Medeco M3]] designs.

__TOC__

== Principles of operation ==

:''See also [[Medeco Biaxial#Principles_of_operation|Medeco Biaxial (Principles of operation)]]''

The M4 uses five or six pin-tumblers that provide axial rotation to interface with a sidebar. It uses standard, [[Security_pins|mushroom]], and barrel drivers.

The M4 sidebar differs from previous models because it has small grooves cut out where the side pins fit into. Once side pins are properly lifted by the correct side bitting and shuttle pin on the key, and pin tumblers are properly rotated by the correct key, the sidebar legs can interface with the gates on each pin-tumbler.

The M4 side pins are spring-biased components located to the left of the sidebar. In their default state, the side pins block the sidebar from retracting. A moveable element on the right side of the key lifts the single Lift Pin into the correct position. Side milling on the key moves the three standard side pins into the correct position. There are three different standard side pins, with true gates at different heights, and false gates.

'''Notes'''
* Original, Biaxial, and M3 sidebars are ''not'' compatible with the M4.

== Disassembly instructions ==

Add to me!

== Vulnerabilities ==

The M4 is thought to be an improvement to the M3, allowing for enhanced key control and pick resistance. Research by the [[locksport]] community has shown a picking attack is possible.

Autom8on: /* History */ - added ref link to US Patent 1,965,336 - Briggs Stratton 1935 sidebar wafer patent...

<span style="font-size: 188%;">{{PAGENAME}}</span>

[[File:Biltema_wafer_lock_disassembled.jpeg|thumb|right|text-top|250px|A disassembled wafer [[cam lock]].]]

A '''wafer''' (or '''wafer tumbler''', '''disc tumbler''', '''plate tumbler''') is a type of [[lock]] design that uses flat metal locking components to directly block rotation of the [[plug]]. Wafer [[key]]s position all wafers at the [[shear line]] to allow the plug to rotate freely.

Wafer locks are popular in a variety of environments, and are classified as low to medium security. Low-security cabinet, desk, and drawer locks are commonly a wafer design. Wafer locks are also the most common form of automobile lock, with many newer models integrating [[Electronic lock|electronic]] components.

[[Disc-detainer]] lock designs use similar locking components, but are instead characterized by round disks that are rotated by the key.

__TOC__

== History ==

The earliest wafer designs were developed by P. S. Felter in 1868 and Hiram S. Shepardson in 1870.<ref>[http://www.google.com/patents?id=N6oAAAAAEBAJ US Patent #76,066 ("Improvement in door locks")]</ref><ref>[http://www.google.com/patents/about?id=j3xPAAAAEBAJ US Patent #99,013 ("Improved lock")]</ref> In the 1930s Chicago Lock and Briggs Stratton began producing wafer locks that used a [[sidebar]]<ref>[https://patents.google.com/patent/US1965336A US Patent #1,965,336 ("Lock")]</ref>.

== Principles of Operation ==

A set of wafers is used to block rotation of the plug at one or more points. Low-security wafer locks traditionally block at a single point, though more advanced models can block at the top and the bottom, as well as alternate the bitting of components to be at the top and bottom of the keyway. When the correct key is inserted, all wafers are properly positioned and the plug is free to rotate and engage the [[bolt]] mechanism.

Master keying is made possible by wafers with stepped or otherwise segregated bitting areas that interact with the change and master keys.

<div align="center"><gallery>
File:Disc_tumbler_locked.png|Wafers prevent rotation of the plug.
File:Disc_tumbler_with_key.png|The correct key raises each wafer to the shear line.
File:Disc_tumbler_unlocked.png|The plug can rotate when all wafers are at the shear line.
</gallery></div>

== Components ==

; Wafers
: A flat piece of metal placed in the plug of the lock as the primary locking mechanism. Each wafer may have a different size or a different protrusion in the center to provide [[differs]]. When wafers are positioned so that they are not protruding from the plug, the plug and cam can rotate to lock or unlock the lock.

; Springs
: On the side(s) of wafers a spring is used to bias wafers out towards the cylinder.

; Plug
: The [[plug]] is the inner piece of the lock that rotates upon insertion and tension of the correct key. The plug is connected to the cam to actuate the bolt mechanism when rotated.

; Cylinder
: The cylinder is the outer piece of the lock that houses the plug. The cylinder is responsible for blocking rotation of the plug when wafers protrude from the plug.

; Cam
: The [[cam]] is an extension connected to the back of the plug which actuates the [[bolt]] mechanism to lock or unlock the lock.

== Vulnerabilities ==

Wafer locks are vulnerable to a variety of attacks:

* [[Lockpicking]]
* [[Impressioning]]
* [[Decoding]]
* [[Bypass]]

'''Notes'''
* Wafer locks are '''not''' vulnerable to [[key bumping]] or [[pick gun]] attacks because they do not use pin-tumblers. Bumping a wafer lock will damage the wafers and may cause the bump key to get stuck in the lock.
* Low-security wafer locks are also subject to ''visual'' decoding based on the resting position of each component.

Autom8on: pondering if it's worth adding some patents to sidebar-based locks of historical note...

Pondering if it's worth adding a section on the history of notable sidebar locks to this page - perhaps mention the 1934/1935 "Briggs and Stratton" sidebar wafer lock patent (1,965,336), and the Medeco Original one (1970 / 3,499,302) at least? I may get round to it eventually... ;p

The '''Everest 29 SL Primus XP''' is a [[UL 437]]-rated [[Slider|slider]] lock made by [[Schlage]]. It uses seven L-pin sliders and five [[Side_pin|finger pins]] with two [[sidebar]]s that require the pins to be raised and rotated properly. The patent protection on the Everest 29 keys will expire in 2029.
