The key that has a transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than a mechanical key. Using special methods, it is possible to duplicate a standard car key, but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.
To activate get more info the transponder chip, the ignition cylinder must be turned on. The ring emits a blast of IR energy, which is absorbed by the microchip in the key. The chip responds by sending a unique code the immobiliser in your car. The computer in the car examines the code in its memory with the transponder's code and if the two codes match it will start the engine.

This can be caused by interference or the system becoming too sensitive. This could require an adjustment. To do this, simply disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the system and make it ready to accept the key again.
The security light is the vehicle immobiliser's method of letting you know that there's a problem with the system. If the light is on when you attempt to start your car, it means that the code stored in the ECU is not compatible with the chip in the key.

The system won't permit the vehicle to start if it doesn't have the correct code. Some models will even notify the owner in the event that someone attempts to use an unapproved key or fob.
