As technology improved, more and more automobile makers began to mix electronic and physical protocols to stop theft.

The key chips contain a unique serial code that transmits a message to the receiver in your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes match the car will begin to begin. If the codes aren't compatible, your vehicle won't start at all.
