As technology advanced the number of car manufacturers began to combine physical and electronic protocols in order to prevent theft.

This energy is absorbed into the chip and it transmits a radio frequency signal with an identification code that corresponds up to the unique serial number of the car's computer system. This is to prevent unauthorized attempts to begin the car as only the right keys can be used.
This type of technology is thought to be more secure than a traditional car key since it makes it more difficult for thieves to "hot wire" the vehicle and then start it.
