On-Board Programming
Modern key fobs are more than just unlock the rear hatch and start your car. They have transponders that communicate with the vehicle using an antenna, and also transfer information like an ID number or even the VIN of the vehicle. This is how the vehicle determines who has the key, and can unlock doors and start the engine. These transponders must also be programmed with immobilizer codes. Some vehicles can be programmed through a simple sequence of steps, while others require specialized software and key programming tools. If the car you're working on is a car with onboard programming, you can learn about it in the owner's manual, or by searching the Internet for "onboard programming steps for X car."
In certain cases the key may need to be cloned and the new key must have the same immobilizer codes as the original one. This is done by using a key programming tool which burns the code to the key. Some vehicles will need the transponder to be completely reprogrammed, which is possible in some instances using an J2534 interface but usually requires the removal of the module and the EEPROM chip to reprogramme.

This type of memory has faster read-write speeds and is usually less costly than ROM.
If you are a locksmith and needs to reprogram a chip within an automobile, you'll need a special device called an automotive programmer. This device can read the EEPROM and cloning it to another chip. This allows you to test different ECUs without damaging the original. It's an excellent tool for anyone working on vehicles.
The EEPROM is the primary controller for the car's immobilizer system. Its unique ID number is transmitted to the transponder chip embedded in your key when it is within the distance of the car's antenna ring. The car then asks the chip to respond, and if it receives an acceptable signal it will allow the engine to start. If the chip fails to respond, the vehicle will enter the security mode, which prevents it from starting.
The EEPROM is located in the Kessy Module, located just above the accelerator pedal. It's a black plastic box with two electrical connectors. To get to it, you'll have to take the pedal off.
