As time passed and technology improved as it did, car manufacturers began blending electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips in the keys have a specific serial number, which transmits signals to the receiver in your car. The signal is then compared to the computer of the car when it is received. If the codes match, then your car will start. If not, it will not start at all.

The chip absorbs this energy and then sends a radio frequency signal that contains an identification code. This code matches the unique serial numbers of the computer system of the car. This prevents unauthorized attempts to begin the car as only the proper keys will be able to do so.
This technology is thought to be more secure than a traditional car key since it makes it harder for a thief "hot wire" the vehicle and start it.
