As technology advanced the number of car makers 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 come with unique serial codes that sends a message 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 are compatible, then your car will begin to start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep an extra car key especially if the system is based on transponders.

The chip absorbs this energy and then transmits a radio frequency signal which contains an identification number. This code is in line with the unique digital serial numbers that are stored in the computer system of the car. This stops any attempts by anyone else to start the car, as only correct keys will be able.

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