As technology improved, more and more automobile makers began to mix physical and electronic protocols to avoid theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.

The key chips inside the keys have a specific serial number, which transmits signals to the receiver inside of your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical the car will begin to start. If the codes don't match, your car will not even start.
