The chip get it power from the antenna ring. The induction circuit is used to charge the battery for the key fob. You can have a dead key fob battery, but the chip to start the engine will still send out a signal to the EWS module because it is receiving the electrical charge from the antenna ring.
You can see from this photo that the chip is a stand-alone chip that is not solder to any circuit board.
