As technology improved the number of car manufacturers began to combine electronic and physical protocols in order to prevent theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to open an automobile.
The key chips in the keys have a specific serial number that transmits an electronic signal to the receiver inside of your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, then your car will start. If not, it won't start at all. This is why you should keep an extra car key especially if the system is transponder-based.

This prevents unauthorized attempts to begin the car as only the right keys can be used.
The technology is believed to be more secure than a conventional car key, as it makes it harder for a criminal to "hot wire" the vehicle to start it.
