Some car keys can be programmed by the owner, however it's best to consult with a professional. This will help prevent any possible damage to the car's computer system and also ensure that the new key is working properly.
How to program the key
Prior to the beginning of the 21st century the majority of cars had basic key systems. Keys were made from metal and featured grooves that correspond with the internal parts of the ignition cylinder. As time passed and technology improved as it did, car manufacturers began blending electronic and physical protocols to stop theft. These key systems also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal an automobile.
The key chips come with unique serial codes that transmits a message to the receiver inside your car. The signal is then compared to the car's computer when it is received. If the codes are identical the car will begin to begin. If not, it will not start at all. This is one of the primary reasons you should keep a spare key for your vehicle, particularly in the case of an electronic transponder.
If you want to learn how to program keys, you'll need some special equipment. You'll also require an uncut key for your specific make and model. You can buy them at an auto locksmith or a locksmith dealership, but it's important to purchase the correct keys. If you use a key that is for another model, it won't work.

The system can also detect lost or stolen cards and deactivate them. Additionally, the most recent models are cloud-based, allowing for remote management and configuration.
Most modern cars are equipped with a keyless entry system. The system works by emitting radio signals that are received by the keyfob. The signals are then compared with the correct code that is stored in the car's computer, and when everything is in order, the car will unlock. If the signals don't match, the car will not start. There are several steps you can follow to program your new key fob, if it isn't already programmed.

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

The key fobs have electronic chips which communicate with the car's receiver via radio signals. The car's computer then compares the code on the key to the one stored in its database.
