It can be programmed car keys with individual bytes, which can be accessed using an address. Each byte is either a 1 (or an 0). When the byte is written to the chip it becomes active, and when it is read the bits are decoded into instructions.

When writing to an EPROM the drain and source terminals are grounded. A high voltage channeled from the control gate passes through the silicon oxide to the floating gate, causing electrons to flow into it and get trapped. The gate's contents to change from a zero to 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless systems components. They are also utilized to maintain the state of the system between power transitions. This is crucial for ICs powered by batteries, since a sudden loss of power will cause the chip reset.

There are a few ways to reprogram an EEPROM however the majority of them require that the vehicle be in a particular condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery or remove the EEPROM and then connect it to an test board.
