Car key programming is a method that allows you to recode the blank chip inside your replacement key so it matches the current settings of your vehicle.

These are usually standalone devices, but they can also be integrated into more complex scanners.

EEPROM Method

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

When writing to an EPROM the drain and source terminals are grounded. A high voltage channeled through the control gate tunnels through the silicon oxide and into the floating gate which causes electrons to flow into it and then become trapped. This causes the gate to change its content from a zero to a 1. When the voltage is cut off 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 be used to maintain state between power changes. This is especially important for ICs that are powered by battery, since a sudden loss of power can cause the chip to reset.

There are a couple of ways to reprogram an EEPROM. However, the majority 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 remove the chip and solder it onto an test board. Then the contents of the EEPROM can be read using an EEPROM reader and transferred to a different chip.

Certain cars might require more time to complete the process to complete, which can be accomplished by connecting the device to the OBD2 port. Certain vehicles may require EEPROM programming, which can take a number of days.
