How do you program a key?
Prior to the beginning of the 21st century, the majority of cars utilized basic key systems. The keys were made of metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As technology advanced, more and more automobile manufacturers began to combine 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 difficult for thieves to get into the vehicle.
The key chips in the keys have a unique serial number that sends an electronic signal to the receiver in your car. The signal is compared to a code in the car's computer when it is received. If the codes match, then your car will begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key for your vehicle, especially when you use transponder-based systems.
You'll require specialized equipment to learn to program keys. You'll need to buy a blank key that matches the model and make of your car. They can be bought at the dealership or through locksmiths, but you must make sure that they are the correct ones. If you use a key for another model, it will not work.
To start the process, you need to insert the new key into the ignition and switch it to the "on" position. You'll need to leave the key in this position for around 10 minutes and 30 seconds. Once the time is up you can take out the key and see whether the security indicator on your dashboard went out. If it didn't go out then you'll need to repeat the procedure for the third time.
Be aware that this method can only work on GM vehicles however it isn't foolproof.

They will have the tools and equipment needed to access the onboard diagnostic port of your car and then make the change.

It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system can also detect stolen or lost cards and then deactivate them. In addition, the latest models are cloud-based and allow for remote management and configuration.
Modern cars come with keyless entry systems. The system works by emitting radio signals that are received by an specialized keyfob. The signals are compared with the code that is stored in the car's computer and, if all is well the car will start to unlock. The car will not start in the event that the signals are not the same. If your key fob is not already programmed, it is possible to follow a few steps to programme it.
First, you'll need to make sure that all doors are locked, except for the driver's side. You'll also require the original key fob as well as any extras you'd like to program.

Transponder Keys
Transponder keys are also known as chip keys. They have a microchip embedded in the head of keys. When the key is placed in the barrel of the ignition lock, and turned to ON the antenna ring emits an energy burst through the transponder chip. This energy is absorbed into the chip and it transmits the radio frequency signal, which includes an identification code that is matched with the unique serial number of the car's computer system. This stops unauthorized attempts to begin the car, as only correct keys will be able.
The technology is believed to be more secure than the traditional car key, as it makes it harder for a criminal to "hot wire" the vehicle and start it. It's not foolproof, and thieves have found ways of tricking and defeating the system. So even cars equipped with transponder keys aren't immune to theft.
You could be able to program a transponder key on your own with an appropriate key programmer for your car. The key programmer comes with a guide that will take you step-by-step through the process.
