As technology advanced the number of car makers began to combine electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it difficult for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number that sends signals to the receiver in your car. The signal is compared with the computer of the car key programmers when it is received. If the codes are similar then your car will start. If the codes aren't compatible, your car will not even start. This is one of the main reasons you should keep a spare key for your vehicle, especially if you have transponder-based systems.
If you want to learn how to program a key, you'll need some special equipment. You'll also need an uncut key for your specific make and model.

This is to prevent any attempts by anyone else to start the car since only correct keys will be able.
This technology is thought to be more secure than the traditional car key since it makes it more difficult for a thief "hot wire" the vehicle and then start it.
