As time passed and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.

The key chips contain a unique serial code 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, then the car will start. If the codes aren't compatible, your car won't even start. This is why it is important to keep a spare car key, especially if the system is based on transponders.

The chip absorbs the energy and then transmits a radiofrequency signal that contains an identification code. The code is matched to the unique serial numbers of the computer of the car. This is to prevent unauthorised attempts to start the car as only the correct keys will be able.

This technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" an automobile and start it.
