Keys

Transponder chips are a typical feature of modern cars and are designed to guard against car theft. The chip is a microcircuit which emits a radio frequency signal when the key is placed into the ignition. The car then scans for the signal and begins the engine if it matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incorrect frequency. This makes it difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.

A circuit board that has an induction coil that connects the key to the chip. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification. The ID number of the key is sent back to the vehicle, and if it matches the engine will begin to run.
