As technology improved the number of car manufacturers began to combine electronic and physical protocols to stop theft. Key systems like these also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal a vehicle.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver inside your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes are compatible, then your car will start. If the codes aren't compatible, your car will not even start. This is one of the main reasons you should keep a spare key in your car, especially in the case of an electronic transponder.

This code is in line with the unique digital serial numbers in the computer system of the car. This prevents unauthorised attempts to start the car since only proper keys will be able to do so.
It is believed that this technology will be more secure than traditional car keys because it makes it much harder for a thief to "hot wire" a vehicle and get it started.
