As time went on and technology advanced, more and more car manufacturers began blending physical and electronic protocols to stop theft. These key systems are also referred to as transponder keys or chips keys, are designed to make it harder for thieves to open a vehicle.
The key chips inside the keys have a specific serial number that transmits an electronic 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, then your car will start. If not, it won't start at all.

The chip absorbs the energy and then transmits a radio frequency signal that includes an identification code. This code matches the unique serial numbers in the computer system of the car. This stops unauthorized attempts to begin the car as only the right keys can be used.
The technology is believed to be more secure than traditional car keys because it makes it much harder for a thief to "hot wire" the vehicle and start it.
