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 harder for thieves to start the vehicle.
The key chips have an unique serial number which transmits a signal to the receiver in your car. The signal is then compared to the car's computer when it is received. If the codes match then your car will begin. If the codes don't match, then your car will not even start. This is why it is important to keep an extra car key, especially if the system is based on transponders.

This helps prevent unauthorised attempts to start the car since only the right key will be able to do so.
The technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" a vehicle and get it started.
