The Basics

The process of programming a car key allows you to recode the chip that is blank in a replacement key so that it matches the car's settings. This allows the key to communicate with and start the vehicle. While it is possible to accomplish this using a regular mechanical car key, modern vehicles require a device called a "car key programmer."

Method of EEPROM

EEPROM stands for electrically erasable programmed memory (EPROM). It is a non-volatile CMOS chip that stores information in computers and other electronic devices. It is programmed to store individual bytes that can be accessed using an address. Each byte may be a 1 or a 0. When the byte is written on the chip it becomes active and, when it is read the bits are decoded into instructions.

When writing into an EPROM, both the source and drain are grounded. A high voltage from the control gate tunnels through the silicon oxide and is able to reach the floating gate. This causes electrons to flow to the gate and get trapped. The gate's contents to change from a zero to one. If the voltage is removed, the gate becomes uncharged and the contents of the EEPROM are erased.

EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations and the statuses of remote keyless system components. They can also be used to maintain state between power changes. This is essential for ICs powered by batteries, as a sudden loss of power will cause the chip to reset.

There are several methods to reprogram an EEPROM however, the majority of them require that the car key programing near me be in a specific state at the time. It might be necessary, for example, to disconnect the ECU and battery or to remove the chip and solder it onto a test board.
