As time went on and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are referred to as transponder key programming keys or chip keys and they're designed to make it more difficult for thieves to start the vehicle.

The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver inside of your car.

This will prevent any an unauthorized attempt to start the car, since only the right key will be able to start the car.
