As technology advanced, more and more automobile makers began to mix electronic and physical protocols to avoid 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 that sends an electronic signal to the receiver in your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, then your car will start. If the codes aren't compatible, your vehicle won't start at all. 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 helps prevent an unauthorized attempt to start the car, as only the correct key will be able to perform the task.
The technology is believed to be more secure than conventional car keys because it makes it much difficult for thieves to "hot wire" the vehicle and get it started.
