How to reduce Kessy immo data file size?
As the instruction, data from 0*800 is secured and every time Key Tool Plus will 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.
