As technology improved the number of car manufacturers began to combine physical and electronic protocols to avoid theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it difficult for thieves to open the vehicle.

The chip absorbs this energy and then transmits a radio frequency signal that contains an identification code. This code is in line with the unique serial numbers of the car's computers. This prevents an unauthorized attempt to start the car because only a valid key can start the car.
This type of technology is thought to be more secure than a conventional car key since it makes it more difficult for a thief "hot wire" the vehicle and start it.
