How do you program a key?
Before the turn of the 21st century the majority of cars had basic key systems. The keys themselves were metal and featured grooves that matched the internal components of the ignition cylinder. As technology improved, more and more automobile makers began to combine physical and electronic protocols to avoid theft. These key systems are known as transponder keys or chip keys and are designed to make it difficult for thieves to start the vehicle.
The key chips inside the keys have a specific serial number that transmits an electronic signal to the receiver inside your car. The signal is compared with a code in the car's computer when it is received. If the codes match, your car will begin to start. If not, it will not start at all. This is one of the main reasons to keep a spare key in your vehicle, particularly if you have a transponder-based system.
You'll require special equipment to learn to program keys. You'll also need to purchase the blank key that matches your specific make and model. You can buy them at a locksmith or a car dealership, but it's important to purchase the correct keys. If you try to use a key from another brand, it won't work.
To begin the process, simply insert the new key into the ignition and switch it to the "on" position. You'll need to keep the key in this position for approximately 10 minutes and 30 seconds. When the time has passed, you can remove the key and check if the security light on your dashboard was gone. If it didn't, you'll need repeat the process another time.
Keep in mind that this method can only work on GM vehicles, and it's still not 100% secure. If you're looking for a more secure and reliable solution, then you should consult a professional locksmith or dealer to get your vehicle programmed with chips. They will have the tools and equipment to access your car's onboard diagnostics port and then make the change.
Keyless Entry Systems
Keyless entry systems provide access to your property without the need for a physical credential. Security is achieved through the combination of sensors and an onboard computing device. This allows you to control the system and monitor its activity from any location on your property, and it eliminates the need for keys or locks. The system is also able to detect and disable stolen or lost cards. In addition, the newest models are cloud-based and permit remote management and configuration.
The majority of modern cars are equipped with an entry system that is keyless. To accomplish this the car emits radio signals which are picked up by a particular key fob. The signals are compared to the code stored in the computer of the car and if everything is well, the car will unlock. If the signals do not match then the car won't start. If your key fob is not already programmed, you may follow a few steps to programme it.
The first step is to make sure that all doors are locked, except for the driver's side. You'll need the original key fob as well as any extras that you want to program.

Transponder Keys
Transponder keys, also known as chip keys, have a microchip embedded in the head of the key. When the key is placed in the barrel of the ignition lock and turned into the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. The energy is absorbed by the chip and sends back a radio frequency signal with an identification code that matches up to the unique serial number that is stored in the car's computer system. This is to prevent unauthorised attempts to start the car as only the correct keys will be able.
This type of technology is thought to be more secure than the traditional car key because it makes it more difficult for thieves to "hot wire" the vehicle and start it. It's not foolproof and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder key are not protected from theft.
You could be able to program a transponder key on your own if you have an instrument that works with your car. The key programmer will come with a guide that will take you step-by-step through the process. Follow the directions and turn on the security light in your dashboard before you start your engine.
