2. Transponder Chip (RFID): This is a passive part that does not rely on the battery. When the card is placed into the dash slot (or brought inside the cabin for hands-free designs), the car releases an electro-magnetic field that powers the chip, validating the car's security code to enable the engine to begin.

Because of this dual-system design, a key card can stop working in different methods. For circumstances, the main locking may quit working, but the car will still begin-- or vice versa.
