This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then turn it on.

A circuit board with an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This creates a signal which is received by the coil and sent to the key's identification number. The key's identification number is sent back to the car, and the engine starts when the identification number is in line with.
