How to program the key
Prior to the beginning of the 21st century, the majority of cars had basic key systems. The keys themselves were metal with grooves that matched the internal parts of the ignition cylinder. As technology advanced the number of car manufacturers began to combine physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys and they're designed to make it harder for thieves to start the vehicle.
The key chips that are in the keys have a specific serial number that transmits signals to the receiver inside of your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are identical, your car will begin to start. If the codes don't match, your car will not even start. This is one of the primary reasons why you should always keep a spare key in your vehicle, particularly if you have an electronic transponder.
You'll require specialized equipment to learn how to program keys. You'll also need the blank key for your specific model and make. They can be purchased from a dealership or by a locksmith, but you must make sure they're the right ones. If you attempt to use a key that is from an alternative model, it will not work.
Start by inserting the new key in the ignition and turning it "on". You'll need to keep the key in this position for about 10 minutes and 30 seconds. After the time has passed you can take off your key and see if the security indicator on your dashboard has gone off. If it didn't, you will need to do it a third time.
Keep in mind that this method will only work on GM vehicles however it isn't 100% secure. If you're looking for a reliable and secure solution then you should visit a locksmith or a dealer to get your car programmed using an embedded chip. These professionals have the necessary tools and equipment needed to access the diagnostic port on your car's motherboard and make the change.
Keyless Entry Systems

The most recent models also permit remote management and configuration and are cloud-based.
Most modern cars come equipped with the keyless entry system. The system works by emitting radio signals that are received by a special keyfob. The signals are compared to the code stored in the computer of the car and if everything is in order the car will start to unlock. If the signals do not match, the car will not start. There are several steps you can follow to program your new key fob, if it's not already programmed.
First, you'll need to ensure all the doors are locked, except for the driver's side. You'll also need the original key fob as well as any extras you want to program.

The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed in the barrel of the ignition lock. The energy is absorbed by the chip and it transmits an audio frequency signal that contains an identification code that matches with the unique serial number in the car's computer system. This prevents unauthorised attempts 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 traditional keys for cars because it makes it much difficult for thieves to "hot wire" a vehicle and start it. It's not foolproof and thieves have found ways to trick and defeat the system. Therefore, even vehicles with a transponder keys aren't safe from theft.
You might be able to program a transponder key by yourself with an appropriate key programmer for your car. The key programmer should include an instruction manual that will guide you through the process of programming your key. Once you have the key and a key programmer, follow the directions carefully and make sure the security light on your dashboard is turned on prior to turning your engine ON.
If you're not comfortable using a key programmer or if your car has more advanced features like remote head keys or smart keys, you can turn to a professional locksmith assistance. They'll have the right tools and equipment to cut your blank key, erase your old one from the car's computer and then program the new one so that it will work correctly.
