As technology improved the number of car manufacturers began to combine electronic and physical 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 inside the keys have a specific serial number that sends an electronic signal to the receiver inside of your car. The signal is compared with the car's computer when it is received. If the codes are similar, your car will begin. If not, it won't start at all. This is why it is important to keep an extra car key, particularly if your system is based on transponders.
