I have opel astra 2004 i want make a second key by Xhorse vvdi2. key learned but not start any idea please how to do.
First of all, read TMS eeprom with vvdi prog (need TMS370 adapter), xprog or UPA USB , after that you find pin code.
Then you can learnt it easy with the PIN by using programmer Tango or OBDSTAR tools.
I solved problem i read TMS by xprog get pin code and programmed with obdstar x300 dp. Very fast.
