As time passed and technology advanced as it did, car manufacturers began blending physical and electronic protocols to protect against theft. These key systems, also known as transponder keys or chips keys are designed to make it harder for thieves to start an automobile.
The key chips inside the keys have a specific serial number, which transmits a signal 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 begin to start. If not, it won't start at all. This is why it is important to keep an extra car key especially if your system is transponder-based.
If you're interested in learning how to program a key, you'll need some special equipment. You'll need to buy an uncut key that matches the model and make of your car.

The signals are then compared to the correct code in the car's computer, and when everything is in order the car will start to unlock. The car will not start when the signals aren't identical. If your key fob isn't already programmed, it is possible to follow a series of steps to program it.

The chip absorbs this energy, and then transmits a radiofrequency signal that includes an identification code. The code is matched to the unique digital serial numbers of the car's computers. This stops unauthorized attempts to begin the car as only the right keys can be used.
The technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" a vehicle and get it started.
