Utilizing special techniques, it is possible to duplicate a standard car key, but not transponder keys. Transponder chips are powered by an infrared signal not battery power.
To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a flash of IR energy that is absorbed by the microchip in the key. The chip responds by sending a unique code to the immobiliser in your car. The computer in the car compares the code stored in its memory with the transponder's code and If the two codes are identical, it will start the engine.

This method is risky and requires a lot of experience to avoid electrocuting oneself. Plus, a lot of modern car thieves have shifted to more sophisticated methods, such as using specialized apps or Bluetooth to hijack the car's data and then remotely control it using their phone.
