Method of EEPROM
The EEPROM is an electrically erasable read-only memory that is programmable (EPROM). It is a permanent CMOS memory chip that is utilized in computers and some other electronic devices to store information. It can be programmed with individual bytes, which are accessed using an address. Each byte could be 1 or 0. If a byte has been recorded to the chip it is activated. The bits are encoded into instructions when the byte is read.
When writing to an EPROM the source and drain terminals are grounded. A high voltage that is channeled from the control gate tunnels through the silicon oxide and into the floating gate which causes electrons to flow through it and get trapped. The gate's contents to change from a 0 to one. If the voltage is removed the gate ceases to be charged, and the contents of the EEPROM are erased.
EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and the status of remote keyless system components. They can also be utilized to maintain the state of the system between power transitions. This is especially important for ICs that are powered by batteries, since a sudden loss of power will cause the chip to reset.
There are a few ways to reprogram an EEPROM. However, most of them require the vehicle to be in a certain state. For instance, it might be necessary to disconnect the ECU from the battery, or remove the EEPROM and then connect it to a test board. Then the contents of the EEPROM can be read with an EEPROM reader and transferred to a different chip.
It can be a time-consuming process, and it is difficult to obtain the correct information. Many people opt to have their cars reprogrammed by a professional instead of doing it at home.

The majority of newer vehicles have upgraded transponders in their electronic keys that require a specially designed programmer to work correctly. A professional can perform this task efficiently, often within less than a minute.
Certain vehicles may require an extended procedure that can be completed by connecting the device to the OBD2 port. Some cars may require EEPROM programming, which could take a number of days.
