Master Lock No 142

2019-09-16T15:35:09Z

Nerixel: Inconsistency - lead paragraph claims no security pins, Vulnerabilities section claims security pins. 142 has no security pins, corrected. Minor model number inconsistency fixed.

= Master Lock No. 142 =



The '''No. 142''' is a [[pin-tumbler]] [[padlock]] made by [[Master Lock]]. The No. 142 is a solid body padlock with a blue plastic cover with the word "Master" inlaid in silver. The [[plug]] is made of brass and does not contain any security pins.

__TOC__
<br clear=all>

== Principles of operation ==

:''See also [[Pin-tumbler#Principles_of_Operation|Pin-tumbler (Principles of Operation)]]''

The No. 142 can only be opened by rotating the [[plug]] clockwise.

== Disassembly instructions ==

The No. 142 cannot be disassembled non-destructively; to disassemble it the lock must be sawed in half. The lock is nonfunctional once disassembled because the padlock body acts as the cylinder for the lock.

== Vulnerabilities ==

The 142's low pin-tumbler count and poor manufacturing tolerances allows it to be easily picked by low skill attackers. It is commonly used in [[locksport]] groups and an introductory lock for beginners to learn.

The 14x series is vulnerable to [[overlift]] attacks, where the entire pin stack can be lifted with a [[comb pick]] into the driver's pin chamber and allowing plug rotation. Additionally, the 14x series tends to use zero-lift pins, and once you can identify these pins you can simply avoid them as the pin rests at the shear line. This means less than the total four pins will need to be lifted to enter the lock.

The No. 142 may be vulnerable to one or more of the following:

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

The No. 141 can only be opened by rotating the [[plug]] clockwise.

== Disassembly instructions ==

The No. 140 cannot be disassembled non-destructively; to disassemble it the lock must be sawed in half. The lock is nonfunctional once disassembled because the padlock body acts as the cylinder for the lock.

== Vulnerabilities ==

The 141's low pin-tumbler count, at 4 pins, and poor manufacturing tolerances allows it to be easily picked by low skill attackers. It is commonly used in [[locksport]] groups and an introductory lock for beginners to learn.

The 14x series is vulnerable to [[overlift]] attacks, where the entire pin stack can be lifted with a [[comb pick]] into the driver's pin chamber and allowing plug rotation.

Lockwood 334 series

= Lockwood 334 series =

{{Lock model
| name = Lockwood 334 series
| Img = File:Lockwood_334B45.jpg
| Img_size = 250
| maker = [[Lockwood]]
| lock_type = [[Padlock]]
| lock_design = [[Pin-tumbler]]
}}

The 334 series of [[padlock]]s is a rekeyable series of 45mm padlocks from [[Lockwood]]. The series features a basic brass-body model (334B45), a stainless steel variant (334S45), a stainless steel closed-shackle variant (334C45), and a marine grade steel variant (334M45).

The 334B45 variant is the most common rekeyable lock body sold by Lockwood in Australia. It, along with the [[ABUS 83|Abus 83/45]], make up the majority of rekeyable padlock bodies sold and used in Australia today. This is due to most locksmiths currently offering the 334B45 body as standard to customers purchasing any of [[Restricted keyways by Lockwood|Lockwood's restricted keyways]] or high-security cylinders. Locksmiths offering [[Restricted keyways by MLAA|MLAA keyways]] also offer the 334B45 padlock body as standard.

__TOC__

<div style="clear:both"></div>

== Features ==

=== Pinning ===
The 334 series contains 5 pins, and can be repinned to 6. These pins are all Lockwood shallow spools, except for one standard pin. It isn't uncommon to come across a second-hand 334 series padlock with all shallow spools, but this usually occurs within larger systems with locksmiths involved.

[[File:Lockwood_334_quickchange_pin.jpg|thumb|The quick change pin for the shackle on the rear of a 334B45 padlock]]
=== Quick change shackle ===
The padlock series features dual ball bearings and an 8.7mm hardened steel shackle with quick-change functionality.<ref>[https://www.lockweb.com.au/en/lockwood-products/padlocks-and-outdoor-security/high-security-range-padlocks/high-security-334-series-brass-case-padlocks/ Lockwood 334B45 product page], Lockwood Australia</ref> To remove or change the shackle, rotate the key fully and depress a small pin located on the back of the body, near the top.

[[File:Lockwood_334_core_rear.jpg|thumb|150px|Tail of a Lockwood 334 cylinder, showing both holes where a key-retaining pin can fit]]
=== Convertible key-retaining status ===
334 cores can be swapped between key-retaining and non-key-retaining by relocating a small pin fitted in the cam of the core. If no pin is present, the padlock operates as non-key-retaining. 334 actuators are of a non-bypassable design.

<div style="clear:both"></div>

== Vulnerabilities ==
When fitted with the stock 334 cylinder, this series of locks may be vulnerable to the following:

* [[Lockpicking]]
* [[Impressioning]]
* [[Key bumping]]

== Disassembly ==

# Unlock the padlock.
# Remove the retaining screw down the open shackle hole to release the cylinder.

Further disassembly is usually not required and can be difficult given the quick-change shackle mechanism. The shackle can be released via quick-change functionality described in [[#Features]] and pins can now be readily accessed with the core removed.

Master Lock No 410

2019-02-03T17:50:02Z

Nerixel: Initial page create.

{{Lock model
| name = Master Lock 410 LOTO
| img = File:Master_No_410.jpg
| maker = [[Master Lock]]
| lock_type = [[Padlock]], [[Cylinder]]
| lock_design = [[Pin tumbler]]
}}

The Master Lock 410 LOTO padlock is a plastic-body lock utilising a ball-bearing locking mechanism.<ref>BosnianBill. [https://www.youtube.com/watch?v=g0qyjS2pNxM Master Lock Lock Out Tag Out (LOTO) Training Locks] (YouTube)</ref> It is designed and marketed towards electricians and maintenance workers, who need to lock out and disable equipment while working on it.

The 410 LOTO is notable as being one of few 6 pin locks manufactured by [[Master Lock]]. It has also achieved notoriety among locksport communities as a well-known practice lock for learning tension control and recognising counter-rotation.

==Principles of operation==

The 410 LOTO is a 6-pin core containing 5 spools and 1 lightly serrated pin<ref name="Gut">Faffler, Billy. [https://www.youtube.com/watch?v=iHyrI7UolAY Master 410 Picked and Gutted] (YouTube)</ref>, in random positions. The keyway is physically restricted by the plastic body to rotate only clockwise, but the core is able to rotate counter-clockwise using a tension wrench underneath the body. The lock can be permanently damaged by rotating the core 180° clockwise, as this can drop the key pins out of the lock or into the lock body.<ref>F3rdNami5h. [https://www.reddit.com/r/lockpicking/comments/8m2ali/master_lock_410_loto_picked_and_gutted/ Master Lock 410 LOTO Picked and Gutted] (Reddit)</ref>

The lock is available with two possible keyways. It is not usually possible to know which a lock will come with until it is opened.

==Disassembly instructions==

The 410 LOTO cannot be disassembled non-destructively. However, it is possible to take it apart relatively easily, while keeping it mostly intact. The plastic lock body can be split using a tool wedged down the shackle hole in some cases, or can be cut along the seam using a rotary tool to weaken the seal.<ref name="Gut" />

==Vulnerabilities==

The 410 LOTO design prevents any shim bypass, either by core or by locking mechanism. However, the padlock is made of plastic and does not have a hardened shackle, and as such is vulnerable to many brute force or heat attacks. It is vulnerable to the following:

* [[Lockpicking]]
* [[Destructive entry]]

Medeco Biaxial

Nerixel: Updated Medecoder reference link to what seems to be the new URL. Link changed 08/08/2017.

{{ Lock model

| related = [[Medeco Original]]<br>[[Medeco M3]]<br>[[Medeco Duracam]]
}}

The '''Biaxial''' is a [[UL 437]] rated [[pin-tumbler]] lock made by [[Medeco]]. It is well known for the use of rotating bottom (key) pins that interface with a [[sidebar]]. The Biaxial is one of the most widely used American [[high security locks]]. It was previously thought to be one of the most secure locks available, but continued research from the [[locksport]] community has proven a variety of attacks are possible, including [[key bumping]].

The Biaxial is a newer version of the [[Medeco Original]] and has since been superseded by the [[Medeco M3]]. The [[Medeco Duracam]] is a [[dimple]] lock form of the Biaxial.

__TOC__

== Principles of Operation ==

The Medeco Biaxial uses five or six pin-tumblers that provide [[axial rotation]] to interface with a sidebar located at 3 o'clock. Pin-tumblers must be properly raised to the shear line as well as rotated so that the sidebar arms can fall into notches on the side of each pin-tumbler. Axial rotation is provided by the design of the bottom (key) pins and angled bitting cuts on the key. There are 6 depths available for pin-tumblers, allowing 7,776 (6<sup>5</sup>) theoretical key [[differs]] in a five pin Biaxial (excluding the sidebar).

The main difference between the Biaxial and the Original is that Biaxial bottom pins sit be'''fore''' or '''aft'''er the center of the bitting cut. This allows for six total positions of the bottom pins, but pins use only three true gate positions. Biaxial pins have their own rotation codes:

<div align="center">
{| class="prettytable"
|-
! Type || Left || Center || Right
|-
! Fore (Biaxial)
| K || B || Q
|-
! Original
| L || C || R
|-
! Aft (Biaxial)
| M || D || S
|}</div>

There are 6 total positions for bottom pins, allowing 7,776 (6<sup>5</sup>) and 46,656 (6<sup>6</sup>) total sidebar differs in five and six pin Biaxials, respectively. True gates on the pins can only be rotated to three positions, so there are only 243 (3<sup>5</sup>) and 729 (3<sup>6</sup>) actual rotational differs in five and six pin Biaxials.

The Biaxial uses 2-3 mushroom top pins in each cylinder to provide manipulation resistance to traditional [[lockpicking]]. The sidebar notches on the sides of the bottom pins may also have false notches to resist manipulation by rotation. In addition, "ARX" pins are used to protect against manipulation by rotation. ARX pins close the sidebar notches before they reach the end of the pin, making it so they cannot be readily grabbed by a tool.

Resistance to forced entry is provided in the form of hardened steel rods and discs. In the plug rods are in the 3, 9, and 12 o'clock positions. In the cylinder, two crescent shaped discs are placed at the 12 and 3 o'clock positions to protect the pin-chambers and the sidebar. As a secondary locking mechanism, the sidebar itself also helps to protect against a variety of forced entry techniques. Bottom pins may also have a hardened steel core to resist drilling.

File:Medeco_Biaxial_pins_aligned.jpg|Sidebar pins properly aligned by the key.
</gallery></div>

'''Notes'''
* Biaxial and Original bottom pins are not interchangeable. They are identified by the position of the flag that limits rotation. The flag is 90° from the true gate in the Original and 180° in the Biaxial.
* The Biaxial can be identified by the the Biaxial logo (a split circle) to the left of the keyway.

== Disassembly instructions ==

Disassembly of the Biaxial is simplified compared to other sidebar-based locks because there are no additional finger pins used in the sidebar.

{{Pin-tumbler standard disassembly}}

'''Notes'''
* When reassembled the sidebar must be pointed down, with the ball bearing facing the front of the plug.

== Vulnerabilities ==

The Biaxial may be vulnerable to one or more of the following:

* [[Lockpicking]]
* [[Decoding]]
* [[Impressioning]]
* [[Key bumping]]

'''Notes'''
* The validity of key bumping attacks against Medeco cylinders has been debated between Medeco and the [[locksport]] community. Research done by [[Marc Weber Tobias]] and Tobias Bluzmanis has shown these systems are vulnerable to a wide variety of attacks, including bumping.
* Lockpicking attacks against this lock were previously thought extremely difficult due to axial rotation. A tool called the "Medecoder", developed by Jon King, made this process much easier and at the same time allowed for decoding of the sidebar code.<ref>King, Jon.
