It can be programmed using individual bytes, which can be accessed using an address. Each byte may be a 1 or a 0. If a byte has been recorded to the chip it becomes active. The bits are decoded 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 travels through the silicon oxide and into the floating gate, causing electrons to flow through it and then become trapped. The gate's contents to change from a 0 to one. When the voltage is removed the gate is uncharged, and the contents of the EEPROM are erased.

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

There are a couple of ways to reprogram car keys an EEPROM. However, the majority of them require the vehicle to be in a particular state. For instance, it could be necessary to disconnect the ECU from the battery, or remove the EEPROM and connect it to the test board.
