Some keys for cars can be preprogrammed by the owner themselves but it is recommended to consult an expert. This will avoid any damage to the car's computer system and also ensure that the new key is working properly.
How do you program a key
Most cars had basic key systems up until the turn of the 21st century. The keys themselves were metal with grooves that corresponded to the internal parts of the ignition cylinder. As time went on and technology improved, more and more car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver inside of your car. The signal is compared to the computer of the car when it is received. If the codes match, then your car will begin to start. If not, it will not start at all. This is why it is important to keep an extra car key especially if your system is based on transponders.
If you're looking to learn how to program keys, you'll require certain equipment. You'll also need to purchase a blank key that matches your specific make and model. They can be bought at a dealership or by a locksmith however, you must be sure they're the right ones. If you use a key from another model, it will not function.

Once the time is up, you can remove the key and observe whether the security indicator on your dashboard was gone. If it didn't, you will need to repeat the procedure for the third time.

If you want a more secure and reliable solution then you should visit a locksmith or a dealer to have the car programmed with an embedded chip. They will have the tools and equipment needed to access the diagnostic port on your car's motherboard and make the switch.
Keyless Entry Systems

The system is also able to detect and deactivate lost or stolen cards. In addition, the newest models are cloud-based and allow for remote management and configuration.
Modern cars come with keyless entry systems. This system works by emitting radio signals which are detected by the keyfob. The signals are then compared to the code stored in the computer of the car and, if all is well, the car will unlock. The car will not start when the signals aren't identical. There are several steps you can take to program your new key fob, if it isn't already programmed.

When the key is placed in the barrel of the ignition lock and then turned into the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. This energy is absorbed into the chip, which then transmits an audio frequency signal that contains an identification code that matches with the unique digital serial number of the car's computer system. 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 much harder for a thief to "hot wire" a vehicle and get it started. But it's not foolproof and thieves have discovered ways to trick and defeat the system - so that even vehicles with transponder keys are not immune from theft.
