However, as time progressed and technology improved, more and more automobile manufacturers began blending electronic and physical protocols to stop theft. Key systems, also known as transponder keys or chips keys, are designed to make it harder for thieves to start a vehicle.
The key chips in the keys have a unique serial number that sends a signal to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes match the car will begin to begin. If not, it won't start at all. This is why it is important to keep an extra car key, particularly if your system is based on transponders.

The energy is absorbed by the chip and it transmits a radio frequency signal with an identification code that matches up to the unique digital serial number in the car's computer system. This prevents an unauthorized attempt to start the car since only the right key will be able to perform the task.
It is believed that this technology will be more secure than traditional car keys because it makes it harder for a thief to "hot wire" an automobile and start it.
