As time went on and technology improved and improved, automobile manufacturers began to combine physical and electronic protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to steal the vehicle.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver in your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes match, the car will start. If not, it will not start at all. This is one of the primary reasons you should keep a spare key for your vehicle, particularly if you have an electronic transponder.
