How do you program a key?
Prior to the beginning of the 21st century, most cars used basic key systems. The keys themselves were just metal and had grooves that corresponded to the internal parts of the ignition cylinder. As technology improved the number of car makers began to mix physical and electronic protocols in order to prevent theft. Key systems like these also known as transponder keys or chips keys, are designed to make it difficult for thieves to steal a vehicle.
The key chips that are in the keys have a unique serial number that sends signals to the receiver inside of your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are compatible, then the car will start. If not, it won't start at all. This is one of the main reasons to keep a spare key in your vehicle, particularly when you use transponder-based systems.
If you're interested in learning how to program a key, you'll need some specific equipment. You'll also need an uncut key for your specific make and model. These can be purchased at a dealership or by a locksmith but you must make sure they're the correct ones. If you use a key from another model, it won't function.
To begin the process, insert the new key into the ignition and switch it to the "on" position. You'll need to keep the new key in this position for approximately 10 minutes and 30 seconds. After the time has expired, you can remove the key and observe if the security light on your dashboard was gone. If it didn't then you'll have to do it again for the third time.
Remember that this method will only work on GM vehicles, and it's still not completely secure.

They have the tools and equipment to access the diagnostic port on your car's motherboard and then make the change.

The most recent models also permit remote management and configuration as well as are cloud-based.
The majority of modern cars are equipped with an entry system that is keyless. This system works by emitting radio signals that are picked up using an specialized keyfob. The signals are compared to the code stored in the computer of the car and, if all is well, the car will unlock. If the signals don't match and the car does not start. There are a variety of steps you can follow to program your new key fob if it's not already programmed.

When the key is placed in the barrel of the ignition lock and then turned into the ON position the antenna ring emits a burst of electromagnetic energy through the transponder chip. The chip absorbs this energy and then transmits a radiofrequency signal which contains an identification number. This code matches the unique digital serial numbers in the car's computers. This helps prevent unauthorized attempts to start the car because only a valid key will be able to do so.
It is believed that this technology will be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" an automobile and get it started. However, it's not foolproof and thieves have found ways to deceive and defeat the system - which means that even cars equipped with transponder keys are not safe from theft.
