Remaining chambers max jump is 6
517174

•
Due to the profile check pin we recommend not to use master pins no. 2 (only 4 or larger), however 2 can be used
in case of "emergency" (no more codes available)
MASTER KEY SYSTEM MANAGEMENT
2-Step Progression (Even/Odd)
•
2-step progression allows us to manage all codes/pins/cuts that our system can use
to generate codes for our master key systems or simply KD/KA cylinders; this way no
keys would be repeated
•
Odd/even codes management: B = odd
•
6 pins generate 64 groups (Even/Odd) from AAAAAA to BBBBBB
•
Depending on the size/complexity one group might be used for more then just one
master key system
A = even
Even A
