The process of programming a car key allows you to reprogram a blank chip in a replacement key to ensure that it is compatible with the vehicle's settings. This enables the key to communicate with the vehicle, and ensures that the key will be capable of starting and running the engine.

The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a permanent CMOS chip that is used to store data in computers as well as other electronic devices. It can be programmed with individual bytes that are accessible via an address. Each byte could be one or zero. When a byte has been written to the chip, it becomes active. The bits are converted into instructions when the byte is read.

When writing into an EPROM the drain and source are grounded. A high voltage from the control gate tunnels into the silicon oxide and reaches the floating gate. This allows electrons to flow to it and then become trapped. This causes the gate to change its content from 0 to 1. When the voltage is cut off, the gate becomes uncharged, and the contents of the EEPROM are erased.

EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations and the status of remote keyless system components. They can also be used to maintain status between power changes. This is especially important for ICs that are powered by batteries because a sudden loss of power could cause the chip to reset.

There are several methods to reprogram an EEPROM. However, the majority of them require that the car to be in a certain state. It could be necessary, for instance, to disconnect the battery and ECU or remove the chip and solder it onto an test board. The contents of the EEPROM chip can then be read with an EEPROM Reader and then copied onto another chip.
