Cheers Autel !  My IM 508 Worked flawlessly through OBD pulling 4 digit PIN and adding a Fobik key on my Daughter In Law's 2010 Grand Caravan. Good Job Autel No need to Optimize the software for this one :-)

 Too bad it was a Family Freebie, but I expect  to get a return on this tool eventually. I used it several times before on other makes without success due to cheap customers supplying Used Toyota Smart keys, or a Nissan Knock off Smart Key from Amazon, or adding a VW Fobik keys where I ended up disabling the remote function of the working Fobik  key using the XP200, however I now have an XP 400 to give that another try if I get another chance.
