As technology improved, more and more automobile makers began to mix 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 steal a vehicle.
The key chips inside the keys have a unique serial number that transmits signals to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, then your car will start. If not, it will not start at all. This is the reason you should keep an extra car key particularly if your system is based on transponders.

This prevents an unauthorized attempt to start the car as only the correct key will be able to perform the task.
The technology is believed to be more secure than traditional car keys because it makes it difficult for thieves to "hot wire" a vehicle and get it started.
