It can be programmed with individual bytes, which can be accessible using an address. Each byte is either a 1 (or a 0). Once a byte is written to the chip it is activated. The bits are decoded into instructions when the byte is read.

When writing to an EPROM the drain and source are grounded. A high voltage channeled from the control gate passes through the silicon oxide and into the floating gate which causes electrons to flow through it and then become trapped. This causes the gate's content to change from a zero to a 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to preserve the state of the system between power transitions. This is particularly important for ICs that are powered by batteries since a sudden loss of power can cause the chip to reset.

There are a couple of methods to reprogram car key an EEPROM. However, most of them require the vehicle to be in a certain state. It could be necessary, for example to disconnect the battery and ECU or to take the chip off and then solder it to the test board.
