This chip sends a passcode to the car's immobilizer unit, which may be built into the PCM, BCM, the instrument cluster smart junction box or standalone module. The system checks the code to ensure it's correct. If it's not, the system will disable parts that are essential to start the vehicle, like the ignition or starter motor.

Transponder Chip
A tiny electronic chip, referred to as transponder, is incorporated inside the head portion of your car keys. This technology was introduced in cars made after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting when you have a duplicate of your
key fob repair service. It works by transmitting the radio frequency signal from the key to the immobiliser system of your car. If the code in the car's computer matches the signal transmitted by the key, it will disable the immobiliser and allow the engine to start.

Utilizing specific methods, it is possible to copy a conventional car key but not transponder keys. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip, the ignition cylinder must be turned to the ON position. The ring emits a burst IR energy that is picked up by a microchip in the key. The chip responds by transmitting a unique code to your car's immobiliser. The car's computer compared the code in its memory with the one from the transponder chip, and when they match the engine will begin to rev.

The security light is an immobiliser's way of warning you of an issue. If the light is illuminated and you try to start your car, it means that the code that is stored in the ECU is not compatible with the chip inside the key. This can happen if you have recently replaced your car key with another that was not programmed to your vehicle or when you've had a damaged swapped ECU.
If this is the case, then it's time to talk to a professional and have the key or the transponder chip properly programmed to your vehicle.

remote car key repairs use a different key for starter. The system works by checking the chip inside the key fob or key,
remote Car key Repairs and transmitting a passcode to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that it doesn't have to been a compromise in the code. The system will not allow the car to start if it does not receive the correct code. Certain models will even notify the owner if they attempt to use an unapproved fob or key.
However it isn't foolproof. Some thieves have managed to bypass the immobiliser by using techniques such as 'hot-wiring.' This involves using the wrong wiring in an automobile to trick the ECU. However, this is pretty risky and requires a lot of experience to carry out the procedure without damaging yourself. Plus, a lot of modern car thieves have switched over to more advanced methods such as using specialised apps or Bluetooth to steal the car's information and remotely control it via their mobile.
