Some keys for cars can be programmed by the owner, however it is recommended to consult an expert. This will avoid any damage to the computer system of the car and will ensure that the key is working properly.
How do you program the key
The majority of cars had basic keys systems prior to the turn of the 21st century. The keys themselves were metal and had grooves that were connected to the internal parts of the ignition cylinder. As time went on and technology advanced as it did, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips inside the keys have a specific serial number, which transmits a signal to the receiver inside of your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical the car will begin to begin to start. If the codes don't match, your vehicle won't start at all. This is one of the main reasons you should keep a spare key for your car, especially in the case of an electronic transponder.
If you're interested in learning how to program a key, you'll need some special equipment. You'll need to buy a blank key that is compatible with the car's model and make. They can be bought at an auto dealership or from locksmiths however, you must be sure they're the correct ones. If you use a key from another model, it will not work.
Start by inserting the new key in the ignition and turning it to "on". You'll need to keep the new key in this position for around 10 minutes and 30 second. When the time has passed you can take out the key and observe whether the security light on your dashboard went out. If not, you'll need to do it again for another time.
This method is only compatible with GM vehicles, and isn't foolproof. If you're looking for a more reliable and secure solution, you can visit an auto locksmith or dealer to have your car programmed with an embedded chip. They will have the tools and equipment to access the onboard diagnostic port of your car and make the change.
Keyless Entry Systems
Keyless entry systems allow access to properties without the requirement for an actual credential. Security is provided by a combination between sensors and an onboard computing device. It is possible to manage and monitor the system from any place within the property. Keys and locks are not required. The system can also detect lost or stolen cards and deactivate them. The latest models also support remote management and configuration and are cloud-based.
Modern cars are equipped with keyless entry systems. The system works by sending radio signals that are detected by the keyfob. The signals are compared to the code stored in the car's computer and if everything is well, the car will unlock. The car won't start when the signals aren't the same. If your key fob is not already programmed, you may follow several steps to program it.

The chip absorbs this energy, and then sends a radio frequency signal that includes an identification code. This code is in line with the unique serial numbers of the computer of the car. This prevents unauthorized attempts to start the car because only a valid key can perform the task.
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 start it. But it's not foolproof, and thieves have discovered ways to deceive and defeat the system - which means that even cars equipped with transponder keys aren't safe from theft.
