With the help of specific methods, it is possible to copy a standard car key but not the transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip the ignition cylinder must be turned to the ON position. The ring emits a flash of IR energy, which is detected by the microchip in the key. The chip responds by sending a unique code the immobiliser in your car. The computer in the car compares the code stored in its memory with the transponder's code and when the two codes match, it will start the engine.
If the immobiliser detects that an unauthorised transponder or key is being used it will shut down the engine and prevent any of its vital components 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 then drive off.

It should be left disconnected for around 15 minutes then reinsert it and begin the vehicle. This will reset the system and allow it to accept your key once more.
The security light is an immobiliser's way of warning you of an issue. If the light is on when you try to start your mobile car key repair, it means that the code that is stored in the ECU is not compatible with the chip on the key. This can happen if your car key was replaced with a new key that's not programmed for the vehicle, or when an ECU has been swapped incorrectly.

It's possible that the system won't accept the key due to a software update or glitch. To test this, insert your key into the ignition and turn the ON position. Do not try to start the car.

Programming
The car immobiliser stops the engine from running when the fob or key is not properly programmed.

This is why it's so hard to defeat.
Modern cars are fitted with this security system in the standard configuration. This makes it really hard to wire the car hot or use a different key as a starter. The system works by analyzing the chip in the key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the code hasn't been compromised. The system won't permit the vehicle to start if it doesn't have the correct code. Some models will even inform the owner in the event that someone attempts to use an incorrect key or fob.
The system isn't 100% secure, however. Some thieves have bypassed the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wires within the wiring of a vehicle to trick the ECU into thinking that the proper key or fob is being used. However, this is quite dangerous and requires a lot of experience to accomplish it without electrocuting yourself. Plus, a lot of modern car thieves have moved over to more advanced methods such as using specialised apps or Bluetooth to take over the car's information and remotely control it from their phone.
Car owners often see warning lights that indicate that the immobiliser has gone off the rails. It can occur for a variety of reasons, but the most frequent is due to a damaged or dead battery on the key fob. A simple replacement can fix this issue.
