Car key programming is a procedure that lets you recode the blank chip in the replacement key so that it matches the current setting of your vehicle. This allows the key to communicate and start the vehicle. Although it is possible to accomplish this with a standard mechanical car key, modern cars require a device known as a "car key programmer."

Method of EEPROM
EEPROM is an acronym for electrically erasable programmed memory (EPROM). It is a permanent CMOS chip which is used to store data in computers and other electronic devices. It can be programmed to store individual bytes that are accessed with an address. Each byte can be either a 1 (or a 0). If a byte has been written to the chip, it is activated. The bits are encoded into instructions when the byte is read.
When writing data into an EPROM the drain and source are grounded. A high voltage channeled through the control gate travels through the silicon oxide to the floating gate and causes electrons to flow into it and then become trapped. The gate's contents to change from a 0 to a 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.
EEPROMs can be used to save the calibration coefficients of sensors, bootloader configurations and the status of remote keyless systems components. They can be utilized to maintain the state of the system between power changes. This is especially important for ICs that are powered by battery, since a sudden power loss will cause the chip to reset.
There are several ways to reprogram an EEPROM. However, most of them require that the car to be in a certain state. It might be necessary, for example, to disconnect the battery and ECU or to remove the chip and place it on a test board. Then, the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip.
