As time passed and technology advanced and improved, automobile manufacturers began blending physical and electronic protocols to prevent theft. Key systems like these are also referred to as transponder keys or chips keys, are designed to make it more difficult for thieves to start a vehicle.

If the codes are identical, your car will begin. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key for your vehicle, particularly in the case of transponder-based systems.

This is to prevent any attempts by anyone else to start the car, as only proper keys will be able to do so.

The technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" the vehicle and get it started.
