How do you program a key?
The majority of cars had basic key systems until the turn of 21st century. Keys were made of metal and had grooves to match the internal components in the ignition cylinder. As time passed and technology improved and improved, automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are also referred to as transponder keys or chips keys, are designed to make it harder for thieves to open an automobile.
The key chips come with unique serial codes that sends a message to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, then your car will start. If not, it won't start at all. This is why it is important to keep a spare car key, especially if your system is transponder-based.
You'll need special equipment to be able to program keys. You'll also require an uncut key for your particular make and model. You can purchase these at a locksmith or a car dealership, but it's essential to get the right ones. If you use a key for another model, it will not work.

After the time has expired, you can remove the key and check whether the security light on your dashboard went out. If it didn't go out you'll have to repeat the process for the third time.

The signals are compared to the code that is stored in the computer of the car, and if all is well the car will start to unlock. If the signals do not match, the car will not start. If automotive key programming has not been already programmed, you can follow a few steps to programme it.

The chip absorbs this energy and then transmits a radiofrequency signal that includes an identification code. This code matches the unique digital serial numbers of the car's computers. This helps prevent an unauthorized attempt to start the car because only a valid key will be able to perform the task.
This technology is thought to be more secure than a conventional car key because it makes it more difficult for a thief "hot wire" the vehicle and start it. It's not foolproof, and thieves have found ways to evade detection and defeat the system. Therefore, even vehicles with a transponder key are not safe from theft.
