As time went on and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips inside the keys have a unique serial number that transmits an electronic signal to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, the car will start. If the codes aren't compatible, your car will not even start. This is the reason you should keep a spare car key, especially if the system is based on transponders.
