As time passed and technology advanced and improved, automobile manufacturers began blending 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 start an automobile.
The key chips in the keys have a unique serial number, which transmits a signal to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, your car will begin to start. If the codes don't match, then your car won't even start. This is one of the primary reasons why you should always keep a spare key for your vehicle, especially if you have a transponder-based system.

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