Transponder Chip

A tiny electronic chip, also known as transponder, is embedded into the head portion of your car keys. The 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 stop your engine from starting if another person has an identical key. It works by transmitting the radio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer matches the signal from the key, it will disarm the immobiliser and allow the engine to start.

The key with the transponder chip is often referred to as a 'fob' or a "smart" key due to the fact that it is more difficult to copy than a conventional mechanical key. It is possible to duplicate a standard key, but not a transponder one. Unlike the remote central locking element of a conventional key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.

To activate the transponder chip, the ignition cylinder needs to be turned to the ON position. The ring emits IR energy that is picked up by a microchip inside the key. The chip then responds with an unique code to the immobiliser of your car. The car's computer checks the code stored in its memory to the one from the transponder chip and If they are compatible the engine will be able to start.

The immobiliser shuts down the engine in the event of an unauthorised transponder or key. It will also prevent any essential components of the vehicle from working.

Security Light

The immobiliser utilizes a small battery to transmit an electrical signal to the chip in your key. It is an anti-theft device that prevents anyone from driving your car without the correct key. If the system is not able to recognize a digital serial from the chip on your key, it will shut off the engine immobiliser to stop the car starting.

The car immobiliser is a great method to deter thieves, but it could occasionally be out of the sync. This can be caused by interference or the system becoming too sensitive. If this is the case, it might need to be reset. To do this, disconnect the battery. After 15 minutes, reinstall the battery and restart the vehicle. This will reset the system and allow it to accept your key once more.

The security light is a way of alerting you to a problem. If the light is on and you attempt to start your car, it means that the code stored in the ECU is not compatible with the chip on the key. This could happen when your car's key was replaced with an alternative key that is not programmed to work with the vehicle, or if the ECU was swapped in a wrong manner.

Programming

An immobiliser for cars prevents the engine of a car from running without a correctly programmed key or fob. It is based on a specific RFID micro-chip that can't be duplicated and has its own digital serial number. The immobiliser will disconnect when it doesn't recognize the code. That's why it's difficult to defeat.

Modern cars have this system as standard. This makes it very difficult to wire a car or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU is then able to determine that it's the right key and that the code hasn't been compromised. The system will not allow the car to start if it doesn't have the correct code. Some models will even report back to the owner in the event that someone attempts to use an incorrect key or fob.

However, the system is not completely secure. Some thieves have managed to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wiring in a vehicle to fool the ECU. This method is risky and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are also employing more sophisticated methods for instance, Bluetooth or other apps that steal a car's information and remotely manage it.

Car owners will frequently be greeted by warning lights that indicate an immobiliser gone haywire. This could be due to a variety of reasons however the most common one is a malfunctioning battery in the keyfob. A simple repair should resolve this problem.
