As time went on and technology improved, more and more car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.

The key chips have unique serial codes that transmits a message to the receiver in your car. The signal is then compared to a code in the car's computer when it is received. If the codes match then your car will begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key for your vehicle, particularly in the case of an electronic transponder.

The energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This prevents an unauthorized attempt to start the car as only the correct key can perform the task.
