Hi.. In my lexus gs300 i checked the immobilizer coil it dsnt get any voltage from the transponder key amplifier but the amplifier itself has 5 inputs and 2 outputs. The outputs goes to coil which shows no voltage but among the 5 inputs 3 inputs has 12v and remaining 2 no voltages... I thought it might be key amplifier problem so i changed with new one... But it also gave the same voltages... So i don't know what next... Do u hv any idea how much the coil should get as a supply voltage and the 5 inputs for amplifier where does it come from.. If possible share block diagram for key amplifier.. Thanks
Hi Paula, I looked on YouTube and programing a Key to a lexus immobilizer looks fairly easy, The link below is that YouTube video,Also there's other lexus videos down the right side of the link that may help as well........CHEERS.. Lexus Remote Immobilizer Key Programming
