It is possible to program certain keys for cars by the owner, but it is best to consult a professional. This will help to prevent any possible damage to the computer system and also ensure that the new key functions properly.
How to Program a Key
Prior to the beginning of the 21st century, the majority of cars utilized basic key systems. The keys themselves were metal and featured grooves that matched the internal parts of the ignition cylinder. However, as time progressed and technology improved as it did, automobile manufacturers began blending physical and electronic protocols to protect against theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it harder for thieves to start the vehicle.
The key chips come with unique serial codes that transmits a message to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes are similar the car will begin to start. If the codes don't match, your car won't even start. This is one of the main reasons to keep a spare key on your vehicle, especially in the case of a transponder-based system.
You'll need special equipment to learn how to program keys. You'll also need an uncut key that matches your specific model and make.

The system can also identify lost or stolen cards and then deactivate them. In addition, the latest models are cloud-based, allowing for remote management and configuration.
Most modern cars are equipped with an entry system that is keyless. To make this work the car emits radio signals that are detected by a particular key fob. These signals are then compared with the correct code in the car's system, and if everything is in order, the car will unlock. If the signals do not match, the car will not start. There are several steps you can take to program your new key fob if it's not already programmed.

The chip absorbs the energy and then transmits a radiofrequency signal that contains an identification code. The code is matched to the unique serial numbers in the computer system of the car. This prevents unauthorized attempts to begin the car since only right keys can be used.
The technology is believed to be more secure than the traditional car key because it makes it harder for thieves to "hot wire" the vehicle and start it. However, it's not foolproof and thieves have discovered ways to evade and defeat the system - so that even vehicles with transponder keys aren't safe from theft.
