As technology advanced, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems also known as transponder keys or chips keys are designed to make it difficult for thieves to start the vehicle.
The key chips contain unique serial codes that transmits a message to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match the car will begin to begin to start. If not, it will not start at all. This is why you should keep a spare car key, particularly if your system is transponder-based.

The chip absorbs the energy and then transmits a radio frequency signal which contains an identification number. This code is in line with the unique digital serial numbers of the car's computers. This will prevent any unauthorised attempts to start the car, because only a valid key can start the car.
This technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" the vehicle and get it started.
