Issue:

Got IMMO data from Kessy module by VVDI Key Tool Plus, load the file into VVDI2to get 7 bytes CS, and it prompts "CRC verify error”.

Solution:

Reduce Kessy immo data file size from 2.25KB to 2.00KB.

How to reduce Kessy immo data file size?

As the instruction, data from 0*800 is secured and every time Key Tool Pluswill get a different result.

So we save data from 0*800 and delete data below 800 (801*900).

Then read 7 bytes CS code without problem, and we can make a dealer key.

Also, we need to save an original key to avoid corrupting data.
