As technology improved the number of car makers began to mix electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle.

The key chips inside the keys have a specific serial number that sends signals to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes are identical then your car will start. If not, it won't start at all. This is why you should keep a spare car key, especially if your system is transponder-based.
