update - tryed other key data - not working.. found issue with mis match data on unit so write new data and truck start..

So think key logic was correct for dump but not a matching set with flash...

thanks again for your help.

[thayer201]

yes i did select ID13 - problem was eeprom contect had been changed before came to me - made keys no luck tryed them all... so had working flash and eep from working truck and used that and coded keys truck started...
