As technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to stop theft. Key systems like these also known as transponder keys or chips keys, are designed to make it harder for thieves to open the vehicle.

The key chips have a unique serial code which transmits a signal to the receiver inside your car. The signal is compared with the computer of the car when it is received. If the codes match, your car will begin to start. If not, it will not start at all. This is the reason you should keep a spare car key, especially if the system is based on transponders.

The chip absorbs the energy and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers in the computer system of the car. This helps prevent unauthorized attempts to start the car since only the right key can perform the task.

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