As time passed and technology improved and improved, automobile manufacturers began blending electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.
The key chips inside the keys have a unique serial number, which transmits an electronic signal to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are identical the car will begin to begin to start. If not, it will not start at all. This is why it is important to keep a spare car key, particularly if your system is based on transponders.
