As technology advanced, more and more automobile makers began to combine physical and electronic protocols to avoid theft. These key systems are referred to as transponder keys or chip keys and are designed to make it harder for thieves to get into the vehicle.
The key chips inside the keys have a unique serial number, which transmits a signal to the receiver inside of 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. 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.

The chip absorbs this energy, and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers in the computer of the car. This is to prevent unauthorized attempts to begin the car as only the right keys can be used.
This type of technology is thought to be more secure than a conventional car key because it makes it harder for thieves to "hot wire" the vehicle to start it.
