Key Fob Replacement and Reprogramming - Why Your Car Won't Start

Typically the battery for the key fob powers the remote opening and locking systems. The immobiliser is not powered by the battery in the key fob. Instead, the immobiliser depends on the transponder chip that is located on the fob or key. The chip transmits a code from the key or fob to the immobilizer unit in the car. It can be integrated into the PCM (power control module) or BCM (brake control module for brake control), instrument clusters, smart junction boxes, or standalone modules. The system will check the code to make sure that it is correct. If the code is incorrect, the system disables elements that are crucial to the start of the car, such as the ignition or starter motor. The car will be nearly impossible to start if you do not have the right key.
The immobiliser system has proven extremely effective at cutting down on car theft since its first introduction.

Transponder Chip
A tiny electronic chip, referred to as a transponder, is built into the head portion of your car keys. This technology was first introduced in cars manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to stop your engine from starting when you have a duplicate of your key. It works by sending a radio frequency from the key to the immobiliser system. If the code stored in the car's computer is in line with the signal sent by the key the immobiliser will then be deactivated and the engine will be able to start.
The key that is equipped with a transponder chip can be referred to as a 'fob' or a "smart" key because it is much more difficult to duplicate than a conventional mechanical key. It is possible to duplicate a standard key, but not a transponder key. Unlike the remote central locking element of a conventional key, that relies on battery power, a transponder chip powered by the infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be switched to ON. The ring emits a flash of IR energy that is picked up by the microchip within the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer checks the code in its memory with the one from the transponder chip, and If they are compatible, the engine will start.
The immobiliser will shut down the engine when it detects an unauthorized key or transponder. It also blocks any essential components of the vehicle from working. Without a functioning engine the vehicle won't be able to move and it could be easy for a criminal to connect the vehicle to a hot wire and drive away.

If you don't, the security light in your vehicle will continue to flash and it will be difficult to start your engine.
Security Light
The immobiliser is powered by a tiny battery that sends an electrical signal to the transponder chip within your key. It is an anti-theft device that prevents anyone from opening your car without the correct key. If the system is unable to detect a serial number digital from the chip in your key, it will disable the engine immobiliser and prevent the car from getting started.
The car immobiliser is a fantastic method to deter thieves, however it can sometimes be out of the sync. This can be due to interference or a system that is too sensitive. If this is the case, it could be necessary to reset. To do this, disconnect the battery. After 15 minutes, reconnect the battery and restart the car. This will reset the system and make it ready to accept your key once more.
The security light is the vehicle immobiliser's method of letting you know that there's a problem with the system. If the light is illuminated and you try to start your car, it is a sign that the code in the ECU is not compatible with the chip on the key. This could happen if have recently replaced your car key with one that was not programmed to your vehicle or in the event that you've had a defective swapped ECU.
If this is the case, then it's time to talk to a professional to have the the transponder chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the keys repair key because of an update or software issue. To test this, insert your key into the ignition and turn the ON position.

Programming
The car immobiliser blocks the engine from running if the fob or key are not programmed correctly. It utilizes a specific RFID chip that can't be duplicated and has a unique digital serial number. The immobiliser will disengage when it is unable to recognize the code. This is why it's so hard to defeat.
Modern cars come with this system as standard. This makes it difficult to hot-wire a car or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU is aware that it's the right key and that there hasn't been a compromise in the code. The system won't allow the car to begin when it doesn't receive the correct code. Some models even notify the owner if they try to use an incorrect fob or key.
The system is not impervious to attack, but it is. Some thieves have been able to bypass the immobiliser by using methods such as 'hot-wiring'. This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU into thinking the appropriate fob or key is being used. But, this technique is quite risky and requires a great deal of experience in order to carry out the procedure without cutting yourself. Additionally, many modern car thieves have switched to more sophisticated methods like using specialized apps or Bluetooth to take over the car's data and then remotely control it via their mobile.
Car owners often see warning lights that signal that the immobiliser has gone haywire. This can happen for various reasons, but one of the most common is a dead or defective battery on the key fob. The issue can be solved by a simple replacement.
If this isn't working the transponder chip could be defective or mismatched with the ECU. This is harder to fix and diagnose as it could require a specialist locksmith or dealership. However, a car immobiliser may also be damaged by water intrusion or even being removed from the fob or key. If you experience any of these problems, it is a good idea to consult a local car dealer or garage to seek help.
