vehicle and keys The EEPROM Method The EEPROM is an electrically eraseable read-only memory programmable EPROM It is a non-volatile CMOS memory chip that is utilized in computers and some other electronic devices to store data It is programmed using individual bytes that are accessible using an address Each byte could be 1 or 0 Once a byte is written to the chip, it becomes active The bits are converted into instructions when the byte is read When writing into an EPROM, both the drain and source are grounded A high voltage that is channeled from the control gate passes through the silicon oxide to the floating gate, causing electrons to flow through it and then become trapped This causes the gate to change its contents from 0 to 1 If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased EEPROMs are often used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components They can also be used to maintain status between power changes This is essential for ICs powered by batteries, since a sudden loss of power can cause the chip to reset There are a variety of ways to reprogram an EEPROM however, the majority of them require that the car be in a specific state at the time For example, it may be necessary to disconnect the ECU from the battery or remove the EEPROM and solder it to an test board The contents of the EEPROM chip can then be read using an EEPROM Reader and copied onto another chip It can be a time-consuming procedure, and it's difficult to obtain the correct information Most people prefer to have their cars reprogrammed by experts rather than trying this at home Find an auto locksmith that is reputable and has sophisticated tools who

communicate with the car before it can be used to start the engine The majority of newer vehicles have upgraded transponders inside their electronic keys that require a specially designed programer to function effectively A professional can accomplish this fast, often within one minute Connecting the device to an OBD2 port can help with a longer procedure Certain vehicles may require EEPROM
