Car key programming is a method that lets you recode the blank chip inside the replacement key so that it matches the current settings of your vehicle. This allows the key to communicate with and start the vehicle. Although it is possible to accomplish this with a standard mechanical car key, modern cars require a device called a "car key programmer."

The EEPROM Method

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

When writing to an EPROM, both the source and drain are grounded. A high voltage from the control gate is absorbed into the silicon oxide before it is able to reach the floating gate. This causes electrons to flow in to it and then become trapped. This causes the gate to change its contents from a 0 into a 1. When the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.

EEPROMs are typically 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 especially important for ICs that are powered by batteries, since a sudden power loss will cause the chip to reset.

There are a couple of methods to reprogram an EEPROM. However, most of them require the vehicle to be in a particular state. It could 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 transferred to a different chip.

Professionals can accomplish this task efficiently, often within less than an hour.

Connecting the device to an OBD2 port can aid in longer-lasting procedures. Some vehicles may require EEPROM programming procedures that can take days.
