Master Keying 20 12

1. Master Keying 2012

2. 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.

3. Single Key Access • The variety of Mul-T-Lock products for use at home, • office, cars etc… can be Master keyed. ONE KEY - ENDLESS “POSSIBILITIES”

4. The design methods • The Matrix method • The Hierarchical method • 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 • Several levels of access authorization, higher levels are authorized to open lower levels • 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

5. 1 level below the General Master GM | 7 differs 2 levels below the General Master GM | 4 MK | 2 differs The Hierarchical Method

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

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

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

9. Master Keying - How Does It Work? The “bottom line” of any Master-key system: • 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 Allowing more than one key combination to operate specific cylinders. To do this:

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

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

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

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

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

15. 2 2 3 D Using Master Pins Here- Cylinder with D3_2 pins is open for ‘D3’ key combination D 3 Cylinder with master pins is open by several key combinations Here- same cylinder is open for ‘D5’ key combinations

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

19. 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).

20. 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

21. 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

22. 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- Z+ A+ B+ C+ AA BB CC DD ZZ Cancelled Y+ Cancelled Z- Cancelled

23. 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. Shear line C - C - C - D4 C2 A1 C4 C3

24. 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. Shear line CC CC D4 C4 C3 C2 A1

25. 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. Shear line C+ C+ D4 C4 C3 C2 A1

26. Solid Plug Pins - Advantages • Always External locking • Less parts inside cylinder - less probability for malfunctions • Easier to assembly • New combination possibilities
