DIY video on how to read your car's engine computer immobilizer EEPROM to program new keys in the event of lost master keys or a replacement ECU.
This video shows you how to copy or reset the engine immobilizer in your Lexus/Toyota or other modern cars. You can copy or clear the EEPROM chip of all previously stored keys and "virginize" it to accept new keys. When the ECU is first plugged up, it will go into Auto Programming mode, and accept 3 master keys and a valet that you insert into the ignition.
