As time went on and technology advanced and improved, car manufacturers began blending electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle.

The key chips come with an unique serial number which transmits a signal to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer.
