The design methods The highest level is the Grand Master key (GM) which may open each cylinder in the system, Lowest levels are related to keys that may open only a single cylinder The Hierarchical method The Matrix method  Using a Matrix chart, Each column represents a Cylinder and each row represents a Key  The customer, with the help of the locksmith, marks the cylinders that each key is allowed to open  Several levels of access authorization, higher levels are authorized to open lower levels

The Hierarchical Method 1 level below the General Master GM| 4 MK | 2 differs 2 levels below the General Master GM| 7 differs

Entrance door - Common cylinder ENTRANCE Several possible solutions, The best one is to use two double sided key The Hierarchical Method X

Branch Common cylinders COMMONCOMMON Supported in Tree mode Recommended only for small systems The Hierarchical method

Every Tree can be represented on a matrix chart cylinders keys Tree – Matrix Relations

We are using the following mechanical elements to create master keying: Master pins (disks) Solid Plug pins Side pins (not in MT5) Master keying profile-set Master Keying - How Does It Work? Allowing more than one key combination to operate specific cylinders. The “bottom line” of any Master-key system: To do this:

The “ Old ” Concept Toothed Key and pins – straight shear line Key Plug pins Body pins Shear line Plug Body

The “ Old ” concept Pins length – for straight shear line key Plug pins Body pins Shear line Plug Body

The “ Old ” concept Replacing plug pin with shorter pin and master pin disk key Plug pins Body pins Plug Body Master pin

The “ Old ” Concept key Plug pins Body pins Plug Body Master pins Replacing another plug pin …

Combination – None Mastered It will be locked for any other key combinations Here- same cylinder is locked for ‘D5’ or other key combinations Cylinder with ordinary pinning is open by a single key combination Here- Cylinder with D3 pins is open for ‘D3’ key combination only! 3 D 3 D

Using Master Pins Cylinder with master pins is open by several key combinations Here- same cylinder is open for ‘D5’ key combinations 2 Here- Cylinder with D3_2 pins is open for ‘D3’ key combination 3 D 2 3 D

Conventions A1 34 B3 2+ B3 1_ Internal master pin ‘4’ Internal plug pin ‘1’ External plug pin ‘A’ External master pin ‘3’ Internal plug pin ‘3’ External plug pin ‘B’ External master pin ‘1’ Internal plug pin ‘3’ External plug pin ‘B’ Solid master pin ‘2’ Available master pins Internal master pin 1 cancelled

GM Combinations Package MUL-T-LOCK provides special GM combination-card for each Master Key system. Each Package contains 10 cards (for 10 systems) with 6 digits number typed on each. An attached list refers a special GM combination for each card (system).

It is highly recommended to separate the master key products from the ordinary products by using different profiles We recommend to use the left hand MKS profiles set Security-convenience trade off

The new profiles set has a structure of 7 profiles open by one master key profile Left Hand MKS Profiles New master key-profile 99 replaces the existing master 11 Three new profiles: 33, 35, 37 are added

Solid Plug Pins New revolution in master keying concept only available in telescopic pins tumblers We took the “multiple shear line” away from the plug shear line and move it into the key side 12 pins divided into 3 different configurations A- B- C- D- AA BB CC DD Z+ A+ B+ C+ ZZ CancelledY+ CancelledZ- Cancelled

Solid Plug Pins  Pins that “ride” only on the external cut  Pins are identified by letter and (-) sign  A-, B-, C-, D- EXAMPLE: Solid Plug Pin C- operated by C4, C3, C2 key cuts. C2 C3C4 C - Shear line D4A1

Solid Plug Pins  Pins that “ride” on either the external cut, internal cut or both  Pins are identified by double letters  AA, BB, CC, DD : EXAMPLE: Solid Plug Pin CC operated by C4 and C4 key cuts. CC C4 C3 Shear line D4 C2A1

Solid Plug Pins  Pins that “ride” only on the internal cut  Pins are identified by letter double letter  Z+, A+, B+, C+ EXAMPLE: Solid Plug Pin C+ operated by C4 and D4 key cuts. C+ C4D4C3 Shear line C2A1

Solid Plug Pins - Advantages 1.Always External locking 2.Less parts inside cylinder - less probability for malfunctions 3.Easier to assembly 4.New combination possibilities
