However, as time progressed and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.
The key chips come with a unique serial code that sends a message to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are identical then your car will begin. If the codes aren't compatible, your car will not even start.
