These key systems are referred to as transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle.    The key chips come with a unique serial code which transmits a signal to the receiver inside your car. The signal is then compared to the computer of the car when it is received. If the codes are similar then your car will begin to start. If the codes aren't compatible, your car won't even start.

This energy is absorbed by the chip and sends back the radio frequency signal, which includes an identification code that is matched with the unique serial number in the car's computer system. This stops unauthorized attempts to begin the car as only the correct keys will be able.    This type of technology is thought to be more secure than a conventional car key, as it makes it harder for a criminal to "hot wire" the vehicle to start it.
