However, as time progressed and technology advanced, more and more automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys and are designed to make it difficult for thieves to get into the vehicle.

The key chips come with unique serial codes that sends a message to the receiver inside your car. The signal is compared to the car's computer when it is received.
