The Basics

Car key programming is a process that allows you to recode the blank chip in the replacement key so that it matches the current setting of your vehicle. This allows the key to communicate with and start the vehicle. While it is possible to accomplish this with a standard mechanical car key, modern vehicles require a device known as a "car key programmer." These are usually standalone devices, but they can also be integrated into more sophisticated scan tools.

The EEPROM Method

The EEPROM is an electrically erasable programmable read-only memory (EPROM). It is a non-volatile CMOS chip which is used to store information in computers and other electronic devices. It can be programmed using individual bytes, which are accessible via an address. Each byte may be 1 or 0. When a 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 drain and source terminals are grounded. A high voltage from the control gate tunnels into the silicon oxide before it gets to the floating gate. This causes electrons to flow to it and then become trapped. This causes the gate to change its contents from a 0 into a 1. If the voltage is removed the gate is uncharged and the contents of the EEPROM are erased.

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

There are several ways to reprogram an EEPROM however the majority of them require that the car be in a specific state at the time. For instance, it might be necessary to disconnect the ECU from the battery or to take the EEPROM out and connect it to the test board. Then, the contents of the EEPROM can be read with an EEPROM reader and copied to another chip.

This process can be lengthy and it may be difficult to get the right data. The majority of people prefer having their cars reprogrammed by a professional instead of doing it at home.

The electronic keys found in the majority of modern cars come with improved transponders that require a special programmer to function properly. A professional can accomplish this quickly, often in less than an hour.

Connecting the device to an OBD2 port can aid in a longer procedure. Certain cars might require EEPROM programming, which can take a few days.
