How to program the key
Before the turn of the 21st century, the majority of cars utilized basic key systems. Keys were made of metal and featured grooves that correspond with the internal parts of the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips that are in the keys have a specific serial number that sends a signal to the receiver inside of your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, your car will begin. If not, it will not start at all. This is one of the main reasons why you should always keep a spare key on your car, especially in the case of transponder-based systems.
If you want to learn how to program keys, you'll need certain equipment. You'll also require a blank key for your specific make and model.

To start the process, you need to insert the new key into the ignition and turn it to the "on" position. You will need to leave the new key in this position for about 10 minutes and 30 seconds. Once the time is up you can take off the key and check whether the security indicator on your dashboard was gone. If it did not then you'll need to repeat the process for the third time.

The most recent models also permit remote management and configuration and are cloud-based.
Modern automobiles are equipped with keyless entry systems. This system works by emitting radio signals that are picked up using the keyfob. The signals are then compared to the code that is stored in the computer of the car, and if all is in order the car will be able to unlock. The car will not start when the signals aren't the same. If your key fob is not already programmed, you may follow several steps to program it.

Transponder Keys
Transponder keys, sometimes referred to as chip keys, have a microchip embedded in the head of the key. When the key is placed in the ignition lock barrel and then turned to the ON position, the antenna ring sends an electromagnetic energy blast through the transponder chip. This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches up to the unique digital serial number in the car's computer system. This will prevent any an unauthorized attempt to start the car since only the right key can perform the task.
The technology is believed to be more secure than traditional car keys because it makes it more difficult for thieves to "hot wire" an automobile and start it. However, it's not foolproof and thieves have found ways to trick and defy the system - so that even cars that have transponder keys aren't protected from theft.

This will save your time and money, and will keep your car's security system operating as it should. Additionally, it's much safer than making it yourself. If you use the incorrect key programming software or follow unofficial guides and the data in your car's system can be corrupted and the new key will not work.
