Transponder chips are a typical feature of modern cars and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the key is placed into the ignition.

A circuit board equipped with an induction coil that connects the chip to the key. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This creates a signal which is absorbed by the coil before being sent to the key's identification.
