As time went on and technology improved, more and more car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are known as transponder keys or chip keys and they're designed to make it harder for thieves to get into the vehicle.
The key chips inside the keys have a specific serial number that transmits an electronic signal to the receiver inside your car.
