As technology improved, more and more car makers began to mix physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.
The key chips that are in the keys have a specific serial number that sends signals to the receiver inside of your car. The signal is compared to the computer of the car when it is received. If the codes match then your car will begin. If the codes don't match, then your vehicle won't start at all.

This is to prevent unauthorized attempts to begin the car since only proper keys will be able to do so.
This technology is believed to be more secure than conventional car keys because it makes it more difficult for thieves to "hot wire" a vehicle and start it.
