This post provides 2 methods to create .11 keys for Mercedes, the first method is to use old SKC calculator, another method is to use newest SKC calculator V1.0.1.2, both methods are verified working well till now.
1. The first method – using old SKC calculator
I try to explain how create .11 dumps to Mercedes keys:
1- Read ezs MCU eeprom
2- Use SKC calculator and generate .21 keys
3- Use Hex editor and open a key dump
4- Create a new empty file
5- Adress 1h is key password, write the 8 bytes inverted in new file at adress 3h
ex: 88 47….D2 must write D2….47 88
6- In new file adress 0h write the key status 14 EC 00
7- In .21 dump adress 9h are the SSID write the 4 bytes inverted at adress Bh in new file
ex: C4 76 6C BC must write BC 6C 76 C4
8- In .21 dump copy all bytes from Dh to 7Ch and past in new dump adress Fh
9- At adresses 7Fh, 80h, 81h and 82h write 01
10- Fill all adresses to the end of dump with 00
11- Last 5 bytes is remark and can be what you whant
12- Write new dump in key mcu and enjoy.
If you can´t transform a .21 dump in a .11 dump with all this information please go fishing and pay to someone to do the job!!
2. The second method- using newest SKC calculator V1.0.1.2 to create .11 keys for Mercedes now new version SKC calculator V1.0.1.2 from www. obdii365.com have .11 generation activated
Then some people may ask where is possible to get the new version?

You can choose the .011 format and test it.
Someone said new skc has .011. But it doesn’t work, it is not true, just try use another key, problem is their key not SKC, and this analysis is confirmed working perfectly.
