The EEPROM Method

EEPROM is an acronym for electrically erasable memory that is programmable car keys (EPROM). It is a permanent CMOS memory chip that is used in computers as well as other electronic devices to store information. It can be programmed using individual bytes, which can be accessible via an address. Each byte can be either a 1 (or a 0). When a byte is written to the chip, it becomes active, and when it is read, the bits are decoded as instructions.

When writing data into an EPROM 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 causes electrons to flow in to the gate and get trapped. The gate's contents to change from a 0 to a 1. When the voltage is cut off, the gate becomes 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 preserve state between power transitions. This is crucial for ICs powered by batteries as a sudden loss of power can cause the chip to reset.

There are several methods to reprogram an EEPROM. However, most of them require that the car to be in a certain state. It may be necessary, for instance, to disconnect the ECU and battery or remove the chip and place it on the test board. Then the contents of the EEPROM can be read by an EEPROM reader and copied to another chip.

It can be a lengthy process, and it can be difficult to obtain the correct information. Most people choose to have their vehicles reprogrammed professionally instead of doing it at home. Find an auto locksmith who is reliable and uses advanced tools who knows what they are doing. This will ensure that the key is correctly programmed and can be used in the vehicle.

In most cases the fob or key must be programmed to communicate with the vehicle before it is able to start the engine. Most newer cars have improved transponders on their electronic keys that require a specially designed programmer to function effectively. A professional can do this fast, often in less than a minute.

Certain vehicles may require an extended procedure that can be completed by connecting the device to the OBD2 port. Certain cars may even require EEPROM programming, which can take days.
