As time passed and technology advanced and improved, car manufacturers began blending electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to open the vehicle.
The key chips have an unique serial number that transmits a message to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, then your car will start. If the codes aren't compatible, your car will not even start.
