As technology advanced the number of car makers began to combine electronic and physical protocols to avoid theft. These key systems are known as transponder keys or chip keys and they're designed to make it harder for thieves to get into the vehicle.

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 with an existing code in the car's computer. If the codes are similar then your car will start. If the codes aren't compatible, your car will not even start. This is the reason you should keep an extra car key, particularly if your system is based on transponders.
