A '''key gauge''' is a [[Locksmithing|locksmithing]] tool used to decode the cut depths of a [[Key|key]]. Key gauges are commonly used for key duplication, [[Decoding|decoding]], and creation of [[Bumping|bump]] keys.

__TOC__

==Styles of Key Gauges==
Key gauges come in various sizes and can often have more than one set of depth information on one gauge.

The most common type of key gauge is used to decode keys to determine the bitting. These usually consist of an angled slope, or stepped slope, indicating depth.

Another form is used for decoding, and also creating keys. By adding a set of spacing markers on an edge of the gauge, a key can be cut to code with nothing more than the key gauge and the skilled usage of an impressioning file.

==Lever Lock Key Gauges==
Lever locks are well suited to be measured and their bitting code determined with a key gauge. The difference in height between successive bitings is clearly visible with the eye. Double and single bitted lever lock keys can be measured in this way. In use the key is placed on the gauge and each bitting is visually decoded by matching it against the appropriate line. Keys can be read or decoded quickly and accurately.

ASSA Twin V-10

}}

The '''Twin V-10''' (or '''V-10''', '''Twin 2''', '''Twin 7000''') is a [[UL 437]] rated [[pin-tumbler]] lock made by [[ASSA]]. The V-10 is part of the Twin series of locks that use pin-tumblers and a [[sidebar]] to provide two layers of security. The V-10 is an updated version of the [[ASSA Twin 6000]] cylinder.

The V-10 is distinct because it is the first of the Twin series to provide geographically distributed sidebar codes to protect against key interchange and unauthorized duplication. It also has a patented key control system that provides a high number of key and sidebar [[differs]].

__TOC__

== Principles of operation ==

The V-10 uses six pin-tumblers and five sidebar finger pins. The top (driver) pins use single and double-spool designs. Counter-milling in the plug chambers works with the spool pins and provides a high level of pick resistance. There are 9 depths available for bottom (key) pins, and four depths available for top (driver) pins. Top and bottom pins are combined to provide a uniform height pin stack that resists attack from [[comb pick]]s as well as reduces wear on the springs. In total, there are 531,441 (9<sup>6</sup>) theoretical key differs for the pin-tumbler portion of the lock.

The sidebar, located in the 8 o'clock position, is pushed out by two springs. The sidebar is interesting because it provides a pre-made set of cuts that must be matched by the finger pins. This contrasts traditional sidebars which have uniform sidebar cuts. In the V-10 system, all finger pins have the same true gates and the key raises them to different positions to match the sidebar. Manipulation protection on the finger pins is provided in the form of false gates above and below the true gate. V-10 finger pins can also be in either the ''for'' (left) or ''aft'' (right) positions. Mono-keyed locks all use the ''for'' position, but [[master key]] systems include both ''for'' and ''aft'' positions. Finger pins can be lifted to five different positions. In total, there are 100,000 ((5*2)<sup>5</sup>) sidebar bittings (3,125 in mono-keyed systems).

The cylinder and plug use a variety of hardened steel inserts to protect against [[forced entry]]. In the plug, steel rods are located at the 9, 12, and 3 o'clock positions. In the cylinder, three rods are located in front of the pin chambers at the 12 o'clock position. Rods near the third pin chamber in the plug and cylinder are also common.

'''Notes'''
* The patent on V-10 key profiles ends in December, 2014.<ref>Fey, Han. [http://toool.nl/images/d/dc/Assa-twin-part1.pdf ASSA Twin Systems (Part 1)]</ref>
* Older V-10 keys list the direct keyway code on the bow of the key. Newer keys use an indirect code.
* The pin-tumbler bitting code is referred to as the ''system code'', and the sidebar bitting code as the ''sidebar code''.

== Disassembly instructions ==

The V-10 is disassembled in the same way as a traditional pin-tumbler cylinder. The sidebar does not cause too many problems when the plug is removed. When the key is removed from the exposed plug the finger pins will be forced out by spring pressure.

{{Pin-tumbler standard disassembly}}

== Vulnerabilities ==

The V-10 system may be vulnerable to one or more of the following:

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

'''Notes'''
* Bumping is possible given a bump key with the correct sidebar bitting. This was a cause for concern when bumping became popular because of the poor distribution of regional sidebar codes in the V-10 system.
