As technology improved the number of car makers began to combine physical and electronic protocols to stop theft. Key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to start an automobile.
The key chips in the keys have a unique serial number, which transmits a signal to the receiver in your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are similar, your car will begin to start. If the codes don't match, then your car will not even start. This is one of the main reasons to keep a spare key in your vehicle, especially in the case of a transponder-based system.

This energy is absorbed into the chip, which then transmits the radio frequency signal, which includes an identification code that is matched up to the unique serial number of the car's computer system. This will prevent any unauthorised attempts to start the car since only the right key can start the car.
This technology is believed to be more secure than traditional car keys because it makes it much harder for a thief to "hot wire" a vehicle and start it.
