The chip transmits a passcode from the fob or key to the immobilizer unit of the car, which could be integrated into the PCM (power control module) or BCM (brake control module), instrument clusters, smart junction boxes, or standalone modules. The system will check the code to ensure it is correct. If it's not then the system will disable components crucial to starting the vehicle, such as the starter motor or ignition.

In cars made after 1995, a small electronic chip called transponder is embedded in the head of your car key.

It works by transmitting radio signals from the key to your immobiliser. If the code on the car's computer is in line with the signal sent from the key, it will disarm the immobiliser and allow the engine 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 more difficult to clone than a conventional mechanical key. It is possible to duplicate a conventional key, but not a transponder one. Transponder chips are powered by an infrared signal not battery power.

To activate the transponder chip the ignition cylinder must be switched to ON. The ring emits a flash of IR energy, which is detected by the microchip within the key. The chip responds by sending a unique code the immobiliser of your car. The computer in the car analyzes the code stored in its memory to the transponder's and If the two codes are identical it will begin the engine.

If the system is unable to detect a digital serial number from the chip in your key, it will disable the engine immobiliser and stop the car from getting started.

The car immobiliser is a fantastic method of deterring thieves, however it can sometimes get out of sync. This can be due to interference or the system is too sensitive. This could need an adjustment. To do this, just disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the system and make it ready to accept your key again.

The security light is a way of warning you of a problem. If the light is on and you try to start your vehicle, it indicates that the code that is stored in the ECU is not compatible with the chip inside the key. This can occur when your car's key was replaced with a new one that is not programmed to work with the vehicle, or if the ECU was not swapped correctly.

If this is the case you should take your mobile key repair near me or transponder chip to a professional for them correctly programmed for the vehicle you are driving.

Modern cars come with this system as standard. This makes it very difficult to hot-wire a vehicle or use a different key as a starter. The system works by analyzing the chip in the key fob or key and sending a passcode back to the ECU (electronic control unit). The ECU then knows that it's the correct key and that the code hasn't been compromised. The system won't allow the car to start if it does not receive the correct code. Some models even notify the owner if they attempt to use an incorrect fob or key.

The system is not foolproof, however. Some thieves have been able to get around the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking the appropriate fob or key is being used. However, this method is pretty dangerous and requires a lot of experience in order to carry out the procedure without cutting yourself. Plus, a lot of modern car thieves have moved to more sophisticated methods, such as using specialized apps or Bluetooth to take over the car's data and then remotely control it using their phones.

Car owners often see warning lights that indicate the immobiliser is malfunctioning. This can happen for various reasons, but one of the most common is a faulty or dead battery in the key fob. A simple replacement can fix the issue.
