As technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to avoid theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.

The key chips come with a unique serial code that transmits a message to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical the car will begin to begin. If not, it will not start at all. This is the reason you should keep an extra car key, especially if your system is based on transponders.
