The bits are then decoded into instructions when the byte is read.

When writing data into an EPROM, Program Car Key both the drain and source are grounded. A high voltage from the control gate is absorbed into the silicon oxide before it reaches the floating gate. This allows electrons to flow to the gate and get trapped. The gate's contents to change from a 0 a 1. If the voltage is removed the gate is 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 state between power transitions. This is especially important for ICs that are powered by battery, since a sudden power loss could cause the chip to reset.

There are a few methods to reprogram an EEPROM however the majority of them require that the car be in a specific state at the time. It could be necessary, for example to disconnect the battery and ECU or to take the chip off and place it on the test board. Then the contents of the EEPROM can be read with an EEPROM reader and copied to a different chip.
