The EEPROM Method

EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a permanent CMOS chip that is used to store information in computers and other electronic devices. It is programmed using individual bytes, which can be accessible via an address. Each byte can be either a 1 (or a 0). Once a byte is written to the chip, it is activated. The bits are then converted into instructions when the byte is read.

When writing to an EPROM, the drain and source terminals are grounded. A high voltage from the control gate tunnels through the silicon oxide and reaches the floating gate. This causes electrons to flow to the gate and get trapped. The gate's contents to change from a 0 to 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 as well as the statuses of remote keyless systems components. They can also be utilized to maintain the state of the system between power transitions. This is particularly important for ICs that are powered by batteries because a sudden loss of power could cause the chip to reset.

There are a variety of ways to reprogram an EEPROM, but most of them require that the car be in a particular condition at the time of. For example, it may be necessary to disconnect the ECU from the battery or to remove the EEPROM and solder it to a test board. Then the contents of the EEPROM can be read using an EEPROM reader and transferred to a different chip.

This process can be lengthy and can be difficult to find the correct data. Many people opt to have their cars reprogrammed by a professional instead of trying this at home. Find an auto locksmith who is reliable and uses advanced tools who knows what they do. This ensures that the key is properly programmed and will function in the vehicle.
