Adding a
2011 BMW M3 CAS3+ key via Autel MaxiIM508 W/XP400. had to updated the cas3
module first then do procedure to add a new blank OEM Key. Key has OEM
internals with aftermarket case.
Question: Have Autel MaxiIM608 (=Autel
MaxiIM508 + XP400) and doing a CAS3 on
the bench today to add key, I checked on the vehicle see if its ISTAP or
not, Can we add key to ISTAP version on the bench? Or must be it be downgraded
in the car first?
Answer: Add key with DME ISN.
Question: So read isn on bench or in car? What if the
CAS has been downgraded? Can a key be added and written to it on the bench?
Answer: I don't do anything in car myself,
always on bench with power supply.
What DME does it have?
If CAS is downgraded (or "upgraded" as autel screen says), it should no longer by key encrypted and you can add a key on bench
I just find it easier and faster to read the DME ISN and add a key
