Here’s an overview on how the immobilizer system works on older Toyota and Lexus vehicles.. 7K ohm resistors, three 5V zener diodes, and a computer with a serial port To connect the 8-pin EEPROM chip to the computer you'll either have to solder hook-up wires to the pins or get a Test Clip for onboard programming.. This is where you need to get a programmer to connect the chip to your PC You can either buy a USB programmer from eBay or make your own to communicate to the serial port.
