Hi thanks for the nice video! I try to "copy key without key" for one W164 ML with keyless go with OBD 2 kabel. I can read the EIS normal, but when I use this option "Make key without key" everythime come error and I can't collect the data. I put the simulation key in "ON" pisition but don't work. Can you tell me where is the problem? Best regards
