How to program a Key
The majority of cars had basic keys systems up until the turn of the 21st century. Keys were made from metal and had grooves to match the internal components in the ignition cylinder. As time passed and technology advanced as it did, car manufacturers began blending physical and electronic protocols to stop theft. These key systems also known as transponder keys or chips keys are designed to make it difficult for thieves to steal an automobile.
The key chips inside the keys have a unique serial number, which transmits an electronic signal to the receiver in your car. The signal is then compared to the computer of the car when it is received. If the codes are similar then your car will start. If the codes don't match, your vehicle won't start at all. This is one of the main reasons to keep a spare key for your vehicle, particularly when you use transponder-based systems.
If you're interested in learning how to program a key, you'll need some special equipment. You'll also need an uncut key that matches your specific model and make.

This will prevent any an unauthorized attempt to start the car as only the correct key will be able to do so.
This type of technology is thought to be more secure than a conventional car key, as it makes it harder for a criminal to "hot wire" the vehicle and start it.
