OMG!
Launch X431 works perfectly!
I FINALLY GOT THE KEY TO START THE ENGINE, LOCK UNLOCK DOOR, OPEN TRUNK AND PROXIMITY ENTRY WORKS!
I can't believe a Autel Maxisys Elite does not work. What is the point of spending all this $ (and then update) and it could not even do a 8 yr old nissan altima, let alone calculating the pin??!!
I obtained the PIN from multiple sources, all gave me the same PIN (new and old years) so it is not the PIN.
I tried manually using Murano as the vehicle, it did not work either.
Looks like Launch X431 V+ is my new favorite now.
