Use real codes instead of fixed 1 - x.
Some codes start with 0, some need to go for the alphabet, some go the other way around...
This is going to be slightly more complicated

• Depth count
• The angle of the cut
• ...

A new system by country's largest manufacturer emerged: FAB New Generation. There are two versions according to the Resistance Class: Fab 3*** "Profi" and FAB 4****. This has the potential to become one of the most popular mechanisms in the region.
The problem is that the number of possible depths is too much for the original project, so it should be rewritten a bit.

Profiles

There are two currently two profiles, one for each RC version:

• B003 for FAB 3***
• B013 for FAB 4****

Patent

The manufacturer claims that the key is patented, however I could not find any published patent yet. The point of the patent seems to be a "double stop"- a classic stop halved into two segments - where one is cut 1mm towards the head of the key. It is apparent how to overcome the patent issue - the 3rd party blanks can be without the cut and it will be OK, probably.

Key specifications:

• no of cuts: 6
• Shaft length (stop to tip): 2570mm*100
• Shaft height: 860mm*100
• Tip height: 300mm*100
• First cut position: 350mm*100 (450 for the second half of the stop)
• Cut width: 120
• Depth granularity: 25mm*100
• Cut distance: 350mm*100

Depths:

The OEM mechanical code seems to go from 0 to at least I. It goes like this:

 0   1   2   3   4   5   6   7   8   9   a   b   c   d   e   f   g   h   i   j   k   l
