It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting if another person has an identical key. It works by transmitting a radio frequency from the key to the immobiliser system. If the code stored in the car's computer matches the signal sent by the key the immobiliser will then be disarmed and the engine will be able to start.
The key with a transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to duplicate than mechanical keys. It is possible to duplicate a conventional key but not a transponder key. Unlike the remote central locking element of a standard key that relies on battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To turn on the transponder, mobile car key repair near me the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy which is detected by a microchip inside the key. The chip then sends an individual code to the immobiliser of your car. The computer in the car examines the code in its memory to the transponder's code and when the two codes match it will begin the engine.
The immobiliser shuts down the engine if it detects an unauthorized key or transponder. It will also prevent all vital parts of the car from working.

If the system cannot identify a digital serial number from the chip inside your key, it will deactivate the engine immobiliser, preventing the car from beginning.
This car immobiliser system is effective in stopping thieves, but it is also possible for it to become out of connection with the key or transponder chip. This can be due to interference or the system becoming too sensitive. This may require an adjustment. To do this simply disconnect the battery. Then leave it off for around 15 minutes, then insert it and start the car. This will reset the system and allow it to accept your key once more.
The security light is the car immobiliser's way of telling you that there's a problem with the system. If you attempt to start your car and the light is solid on it indicates that the chip inside your key isn't in sync with the code that is stored in the ECU. This can happen if your car key has been replaced with a new key that's not programmed to work with the vehicle, or if the ECU was swapped in a wrong manner.

It's tough to beat.
Modern cars have this system as standard. This makes it very difficult to hot-wire a car or utilize a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU recognizes that it is the correct key and that there hasn't been a compromise in the code. The system will not allow the car to start when it doesn't receive the correct code. Some models even notify the owner if they attempt to use an incorrect fob or key.
However, the system is not foolproof. Some thieves have bypassed the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking that the correct key or fob is being used. But, this technique is pretty risky and requires a great deal of knowledge of how to do it without cutting yourself. In addition, many modern car thieves have moved to more sophisticated methods, such as using specialized apps or Bluetooth to steal a car's data and remotely control it via their phone.
Car owners will often get warning lights that indicate that the immobiliser is malfunctioning. It can happen for many reasons, but the most common one is a faulty battery in the keyfob. A simple repair should resolve this issue.
