As time passed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to protect against theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.
The key chips have an unique serial number that transmits a message to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes match, the car will start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep an extra car key, particularly if your system is based on transponders.

This will prevent any unauthorised attempts to start the car since only the right key will be able to perform the task.
This type of technology is thought to be more secure than a conventional car key because it makes it difficult for thieves to "hot wire" the vehicle and then start it.
