Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Currently, most vehicles come equipped with an engine immobilizer in order to prevent car theft. If your vehicle will not start after inserting the key fob, it could be an issue with a transponder that's not sending a security signal to the immobilizer.

The key fob battery powers the remote locking and opening systems. However, it doesn't provide power to the immobiliser. Instead, the immobiliser depends on the transponder chip on the fob or key. The chip transmits a code from the fob or key to the immobilizer unit of the car. It can be integrated into the PCM (power control module) or BCM (brake control module), instrument clusters smart junction boxes or standalone modules. The system then validates the code to make sure it is correct. If the code is not correct the system will disable components that are crucial to the start of the car, such as the ignition or starter motor. The car will be impossible to start if the driver doesn't have the right key.
Since its introduction, the immobiliser has been an extremely effective tool in reducing car theft. Even so thieves are always seeking ways to bypass these security measures.

Transponder Chip
A tiny electronic chip, referred to as transponder, is incorporated inside the head portion of your car keys. This technology was first introduced in cars made after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting if you have an identical key. It works by transmitting an audio signal from the key to your immobiliser. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be removed and the engine will start.
The key with the transponder chip is often referred to as"fob" or a "smart" key because it is much more difficult to clone than a conventional mechanical key. It is possible to duplicate a conventional key but not a transponder key. In contrast to the remote central locking element of a standard key that relies on battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a flash of IR energy which is absorbed by the microchip inside the key. The chip then responds with an unique code to the immobiliser in your car. The car's computer analyzes the code stored in its memory to the transponder's code and If the two codes are identical it will begin the engine.
If the immobiliser detects an unauthorized transponder or key is in use it will shut down the engine and prevent any of its essential components from functioning.

If the system cannot detect a serial number digital from the chip inside your key it will disengage the engine immobiliser, preventing the car from getting started.
The car immobiliser system is an an effective way to stop thieves, however it can get out of sync with the key or transponder chip. This can be due to interference or an immobiliser that is too sensitive. If this is the case it might need to be reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and restart the car. This will reset the key system so that it is ready to accept your keys again.
The security light is an immobiliser's way of warning you of the presence of a problem. If you try to start your car and the light is solid on it means that the chip inside your key doesn't match the code stored in the ECU.

The immobiliser will disconnect in the event that it is unable to recognize the code. This is why it's so hard to defeat.
Modern cars are equipped with this security system by default. This makes it extremely difficult to hot-wire a car or utilize a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU is then able to determine that it's the correct key and that more info the code more info isn't compromised. The system will not allow the car to begin when it doesn't receive the correct code. Certain models will even notify the owner when they attempt to use a wrong fob or key.
