Method of EEPROM

EEPROM is the abbreviation for electrically eraseable programmed memory (EPROM). It is a permanent CMOS memory chip that is used in computers as well as other electronic devices to store data. It can be programmed to store individual bits of data that are accessed with an address. Each byte may be one or zero. When the byte is written to the chip it becomes active and, when it is read the bits are decoded to give instructions.

When writing to an EPROM the source and drain terminals are grounded. A high voltage channeled from the control gate tunnels through the silicon oxide and into the floating gate and causes electrons to flow through it and then become trapped. The gate's contents to change from a 0 a 1. When the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

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

There are several methods to reprogram an EEPROM however, the majority of them require that the car be in a certain condition at the time of. For example, it may be necessary to disconnect the ECU from the battery or to remove the EEPROM and then connect it to a test board. The contents of the EEPROM chip can be read by an EEPROM Reader and copied onto another chip.

Many newer cars come with improved transponders on their electronic keys, which require a special programmer to function effectively. A professional can do this fast, sometimes within a minute.

Connecting the device to an OBD2 port can help with longer-lasting procedures. Some cars might even need EEPROM programming which can take a few days.

The process may seem straightforward but it's difficult to execute correctly and could cause serious system damage if not done correctly. Therefore, it's recommended to consult a professional and be cautious about DIY key programming.

There are several ways to program a brand new car key. One method is called On-Board Key Programming. This involves inserting the new key into the ignition and turning it on. Once the key is in, you need to wait for a couple of minutes before turning it off. The reason for this is that the system resets its commands after a certain amount of time.
