As technology advanced, more and more automobile makers began to mix physical and electronic protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it harder for thieves to open the vehicle.

The key chips inside the keys have a specific serial number, which transmits a signal to the receiver inside of your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are identical the car will begin to begin. If not, it won't start at all.
