How do you program a key?
Most cars had basic key systems until the turn of the 21st century. The keys themselves were metal with grooves that matched the internal components of the ignition cylinder. As time passed and technology advanced, more and more car manufacturers began blending electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to start the vehicle.
The key chips have unique serial codes that transmits a message to the receiver inside your car. When the signal is received it is compared 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, especially if the system is transponder-based.
If you want to learn how to program keys, you’ll need some specific equipment. You’ll need to buy an uncut key that matches the car’s model and make.

In addition, the newest models are cloud-based and allow for remote management and configuration.

The signals are compared to the code that is stored in the computer of the car and if everything is in order, the car will 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 few steps to programme it.

The chip absorbs this energy and then transmits a radiofrequency signal which contains an identification number. The code is matched to the unique serial numbers that are stored in the car’s computers. This is to prevent any attempts by anyone else to start the car since only right keys can be used.
The technology is believed to be more secure than a conventional car key since it makes it harder for a criminal to “hot wire” the vehicle and start it. But it’s not foolproof, and thieves have found ways to trick and defy the system – so that even cars that have transponder keys aren’t protected from theft.
