How to program a Key
The majority of cars had basic key systems up until the turn of the 21st century. Keys were made from metal and featured grooves that match the internal components in the ignition cylinder. As technology advanced, more and more automobile makers began to mix physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.
The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes are similar, your car will start. If not, it will not start at all. This is one of the primary reasons to keep a spare key on your vehicle, particularly if you have an electronic transponder.
If you want to learn how to program keys, you'll need certain equipment. You'll need to buy a blank key that matches the model and make of your car. These can be purchased at an auto dealership or from locksmiths but you must make sure that they are the right ones. If you try to use a key from another model, then it will not work.
Start the process by inserting the new key into the ignition and turning it "on". You will need to leave the new key in this position for about 10 minutes and 30 seconds. After the time is up you can take out your key and check if the security indicator on your dashboard has gone off. If it didn't then you'll have to do it again for another time.
Remember that this method will only work with GM vehicles, and it's still not foolproof.

Additionally, the most recent models are cloud-based, allowing for remote management and configuration.
Modern automobiles are equipped with keyless entry systems. To make this work, the vehicle emits radio signals which are picked up by a special key fob. These 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 do not match and the car does not start. If your key fob is not already programmed, you can follow a few steps to program it.

Transponder Keys

When the key is placed in the ignition lock barrel and turned to the ON position, the antenna ring sends an energy burst through the transponder chip. This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches with the unique digital serial number of the car's computer system. This prevents an unauthorized attempt to start the car because only a valid key will be able to start the car.
The technology is believed to be more secure than the traditional car key since it makes it harder for thieves to "hot wire" the vehicle and start it. It's not foolproof and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not protected from theft.
