Ok, so the code is not working. I login via AlfaOBD with code 93900, I try to store new remotes and AlfaOBD immediately says the code is wrong, so the unit doesn't accept the procedure... Should I buy UPA to read the chip? I have XPROG-m, as I said earlier, so maybe the reading via this was wrong... I also have CarProg 4.01, do you think this box can read the HC05 without any problem? Or should I buy the UPA and don't risk messing the chip with CarProg?
