It can be programmed car keys with individual bytes, which are accessible via an address. Each byte may be 1 or 0. If a byte has been written to the chip, it becomes active. The bits are converted into instructions when the byte is read.

When writing to an EPROM, the source and drain terminals are grounded. A high voltage channeled from the control gate tunnels through the silicon oxide to the floating gate which causes electrons to flow into it and become trapped. The gate's contents to change from a 0 to one. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents 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 state between power transitions. This is essential for ICs powered by batteries since a sudden loss of power will cause the chip to reset.

There are a variety of methods to reprogram an EEPROM however the majority of them require that the car be in a certain condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery or to take the EEPROM out and connect it to an test board.
