How to program the key
Prior to the beginning of the 21st century, the majority of cars utilized basic key systems. Keys themselves were metal and featured grooves that were connected to the internal components of the ignition cylinder. As technology improved, more and more car manufacturers began to combine physical and electronic protocols to stop theft. Key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to steal the vehicle.
The key chips inside the keys have a specific serial number that sends an electronic signal to the receiver inside 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 your car will begin to start. If not, it won't start at all. This is why you should keep a spare car key, especially if the system is transponder-based.
You'll require special equipment to learn how to program keys. You'll need a blank key that matches the car's model and make. 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 for another model, it will not function.
To begin the process, insert the new key into the ignition and switch it to the "on" position. automotive key programming is necessary to keep the key in this position for approximately 10 minutes and 30 seconds. When the time has passed you can take out the key and observe if the security light on your dashboard was gone. If not, you'll need to do it again for a third time.
Keep in mind that this method will only work with GM vehicles, and it's still not foolproof. If you're looking for a safer and reliable option, you should consult an expert locksmith or dealer to get your vehicle programmed with chips.

The latest models also support remote management and configuration as well as are cloud-based.
Most modern cars are equipped with an entry system that is keyless. The system works by sending radio signals which are picked up using the keyfob. The signals are compared to the code stored in the computer of the car and, if all is well the car will start to unlock. The car won't start if the signals are not the same. If your key fob has not been already programmed, you can follow several steps to program it.
You'll first need to be sure that all doors except the driver's door are locked. You'll need to have the original key fob along with any other devices you wish to program.

Transponder Keys
Transponder keys, also referred to as chip keys, are equipped with an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is put in the barrel of the ignition lock. This energy is absorbed into the chip and it transmits a radio frequency signal with an identification code that is matched with the unique digital serial number in the car's computer system. This prevents unauthorized attempts to begin the car since only proper keys will be able to do so.
This technology is thought to be more secure than a conventional car key since it makes it more difficult for thieves to "hot wire" the vehicle and then start it. However, it's not foolproof and thieves have found ways to trick and defy the system - so that even cars with transponder keys aren't immune from theft.
Based on the make and model of your vehicle, you may be capable of programming a new transponder key by yourself by using a key programming device that's compatible with your specific car.
