As time passed 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 harder for thieves to start the vehicle.
The key chips come with an unique serial number that transmits a message to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes match, the car will start. If not, it won't start at all. This is one of the main reasons to keep a spare key in your car, especially in the case of transponder-based systems.

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that corresponds with the unique digital serial number of the car's computer system. This prevents unauthorized attempts to begin the car as only the proper keys will be able to do so.
