As time went on and technology improved, more and more automobile manufacturers began blending electronic and physical protocols to stop theft. Key systems, also known as transponder keys or chips keys are designed to make it difficult for thieves to open a vehicle.
The key chips contain an unique serial number that sends a message 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 match, the car will start. If the codes don't match, your car will not even start. This is one of the main reasons why you should always keep a spare key in your vehicle, particularly in the case of an electronic transponder.
