As technology advanced the number of car manufacturers began to combine electronic and physical protocols to stop theft. Key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to start the vehicle.

The key chips in the keys have a unique serial number that transmits a signal to the receiver inside your car. The signal is then compared to a code in the car's computer when it is received. If the codes are identical, your car will start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key on your vehicle, especially if you have transponder-based systems.

The chip absorbs this energy, and then transmits a radiofrequency signal which contains an identification number. This code matches the unique digital serial numbers of the computer of the car. This helps prevent unauthorized attempts to start the car as only the correct key will be able to perform the task.

It is believed that this technology will be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" a vehicle and start it.
