Utilizing specific techniques, it is possible to copy a standard car key, but not transponder keys. In contrast to the central locking element remote key repairs of a standard key which is powered by batteries, a transponder chip powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst IR energy that is detected by a microchip inside the mobile key repair. The chip then sends a unique code to the immobiliser inside your car. The car's computer compares the code stored in its memory to the one from the transponder chip and If they are compatible, the engine will start.

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 you try to start the car and the light stays on it indicates that the chip in your key doesn't match the code stored in the ECU. This can happen if you have recently replaced the car key with one that isn't programmed to the vehicle or when you've had a damaged swapped ECU.

The system will not allow the car to start if the doesn't have the correct code. Some models will even inform the owner in the event that someone attempts to use a wrong key or fob.
