As time went on and technology advanced and improved, automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.
The key chips come with an unique serial number which transmits a signal to the receiver in your car. The signal is compared with an identifier in the car's computer when it is received.
