As technology improved the number of car 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 more difficult for thieves to steal an automobile.
The key chips inside the keys have a specific serial number that transmits signals to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes are identical the car will begin to begin. If not, it won't start at all. This is why it is important to keep a spare car key, especially if your system is transponder-based.
You'll need special equipment to be able to program keys. You'll need a blank key that is compatible with the model and make of your car.

This will prevent any an unauthorized attempt to start the car since only the right key can perform the task.
This type of technology is thought to be more secure than a conventional car key since it makes it difficult for a criminal to "hot wire" the vehicle and start it.
