Master Keying Master keying allows the customer to design which keys will or will not open which locks in the system. Virtually endless possibilities All Products can be master keyed Easy design & planning Simple keying & pinning User-friendly software Get rid of the overloaded key ring, Replace it with a S I N G L E K E Y.

The design methods • The Hierarchical method Ø Several levels of access authorization, higher levels are authorized to open lower levels • 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 Matrix method Ø Using a Matrix chart, Each column represents a Cylinder and each row represents a Key Ø The customer, with the help of the locksmith, marks the cylinders that each key is allowed to open

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

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

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

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

Master Keying - How Does It Work? The “bottom line” of any Master-key system: Allowing more than one key combination to operate specific cylinders. To do this: We are using the following mechanical elements to create master keying: • • Master pins (disks) Solid Plug pins Side pins (not in MT 5) Master keying profile-set

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

Combination – None Mastered D 3 Cylinder with ordinary pinning is open by a single key combination Here- Cylinder with D 3 pins is open for ‘D 3’ key combination only! D 3 It will be locked for any other key combinations Here- same cylinder is locked for ‘D 5’ or other key combinations

Using Master Pins 2 D 3 Here- Cylinder with D 3_2 pins is open for ‘D 3’ key combination Cylinder with master pins is open by several key combinations Here- same cylinder is open for ‘D 5’ key combinations

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).

Security-convenience trade off 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

Left Hand MKS Profiles The new profiles set has a structure of 7 profiles open by one master key profile 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 AA Z+ A- BB A+ B- CC B+ C- DD C+ D- ZZ Cancelled Y+ Cancelled Z- Cancelled

Solid Plug Pins Ø Pins that “ride” only on the external cut Ø Pins are identified by letter and (-) sign Ø A-, B-, C-, D- EXAMPLE: Solid Plug Pin C- operated by C 4, C 3, C 2 key cuts. Shear line D 4 C- C- C- C 4 C 3 C 2 A 1

Solid Plug Pins Ø Pins that “ride” on either the external cut, internal cut or both Ø Pins are identified by double letters Ø AA, BB, CC, DD EXAMPLE: Solid Plug Pin CC operated by C 4 and C 4 key cuts. Shear line D 4 CC CC C 4 C 3 C 2 A 1

Solid Plug Pins Ø Pins that “ride” only on the internal cut Ø Pins are identified by letter double letter Ø Z+, A+, B+, C+ EXAMPLE: Solid Plug Pin C+ operated by C 4 and D 4 key cuts. Shear line C+ C+ D 4 C 3 C 2 A 1

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