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

The key fob battery powers the remote locking and opening systems. However, it doesn't supply power to the immobiliser. Instead, the immobiliser depends on the transponder chip that is located on the fob or key. This chip transmits a code to the immobilizer unit of the car, which may be built into the PCM, BCM or instrument cluster, smart junction box or standalone module. The system examines the code to ensure it's correct. If the code isn't correct the system will disable components that are essential to starting the car, such as the ignition motor or starter motor.

If the issue continues, it could be due to electrical problems or wiring issues. If this is the case, it's best to have a professional diagnose and repair the issue.
Transponder Chip
In vehicles manufactured after 1995, a small electronic chip called transponder is embedded in the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its function is to prevent the engine from starting when you have a duplicate of your key. It works by transmitting an audio signal from the key to the immobiliser system. If the code stored in the computer of the car matches the signal sent by the key the immobiliser will then be removed and the engine will be able to start.
The key that is equipped with a transponder chip can be referred to as"fob" or a smart key because it is more difficult to duplicate than a conventional mechanical key. Using special methods, it is possible to duplicate a standard car key, but not transponder keys. Contrary to the central locking element remote of a conventional key which is powered by batteries the transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder has to be turned to the ON position. The ring emits a flash of IR energy which is detected by the microchip inside the key. The chip responds by sending a unique code to the immobiliser of your car. The car's computer compares the code stored in its memory to the transponder's and if the two codes match, it will start the engine.
If the immobiliser detects that an unauthorised transponder or key is in use, it will disable the engine and block any of its essential components from functioning.

If the system is unable to detect a serial number digital from the chip inside your key, it will deactivate the engine immobiliser and stop the car from beginning.
This car immobiliser system is effective in stopping thieves, however it can be out of in sync with the key or the transponder chip. This could be due to interference or an immobiliser that is too sensitive. This could require a reset. To do this, disconnect the battery. After 15 minutes, you can reinstall the battery and restart the car. This will reset the key system to ensure that it is ready to accept your keys once again.
The security light is a way of alerting you to an issue. If the light is on when you attempt to start your vehicle, it indicates that the code in the ECU does not match the chip on the key. This can happen if your car key has been replaced by a new one that is not programmed to work with the vehicle, or if the ECU was swapped in a wrong manner.
If this is the case then it's time to talk to a professional to have the transponder or key chip properly programmed to your vehicle.

The immobiliser will stop working in the event that it doesn't recognize the code. That's why it's so difficult to defeat.
Modern cars are fitted with this security system by default. This makes it very difficult to connect the car to a hot wire or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and hasn't been a compromise in the code. The system won't permit the vehicle to start if it does not receive the correct code, and some models will even report back to the owner if a person tries to use an incorrect fob or key.
The system is not 100% secure, however. Some thieves have bypassed the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wiring in a vehicle in order to cause a malfunction in the ECU. However, this method is pretty dangerous and requires a lot of knowledge of how to carry out the procedure here without cutting yourself. Modern car thieves are employing more sophisticated methods such as Bluetooth or other apps that steal website a car's information and remotely control it remotely.
Car owners often see warning lights that signal that the immobiliser has gone off the rails. This could be due to many reasons, but the most common one is a faulty battery in the keyfob. A simple repair should resolve the issue.
