If you unlock CAS OBD and if you have secret file it will not ask ISN for programming key you can do keys with the secret file.

But you must do key. this is a pain because one has to split the key to reset it.

Sorry for replay, for AH users and admin. They are a lot of tools who can decrypt isn in ews5 by dump and working key over 4-5 years ago. Why A H can't do it? is an expensive tool. AH team focus on hexprog tool with ecu cloning and programming, Which can never surpass other top tools in this field, like FLEX, autotuner etc....... You better limit yourself to BMW and that's it.

We all know that Microtronik support can help, but would be interesting to get more info what exactly was done in your situation. It might help others in the future too. Otherwise this forum makes no sense if users are redirected to the support and the topic is closed without solution being posted here. IMHO

..yes , you got that one okey with hexprog that's okey _ buh tht CAS4 isnt encrypted (perhaps not ews5 active as said) Microtronik even says thts not possible on ews5 active CAS to decrypt with key as we do on CAS3+ 🤗 but not like to say you cant proceed your work on ews5 active CAS, yu can with AUTOHEX its just a different way how it does it if yu dont have DME/DDE ISN !!!

when I read it with AH it said that EWS5 is active so I asked for help from Microtronic. I tried this one I read with Hexprog and it passed .
