How to program the key
The majority of cars had basic keys systems prior to the turn of 21st century. The keys themselves were metal with grooves that matched the internal components of the ignition cylinder. As technology improved, more and more automobile makers began to mix electronic and physical protocols to avoid theft. Key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to steal the vehicle.
The key chips in the keys have a specific serial number that sends an electronic signal to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are identical, your car will start. If not, it won't start at all. This is one of the primary reasons why you should always keep a spare key for your car, especially if you have a transponder-based system.

The newest models also allow remote management and configuration, and are cloud-based.
The majority of modern cars are equipped with the keyless entry system. To accomplish this it emits radio signals that are detected by a particular key fob. The signals are then compared to the code stored in the car's computer and, if all is in order the car will be able to unlock. If the signals don't match then the car won't start. If your key fob has not been already programmed, you may follow several steps to program it.

The code is matched to the unique digital serial numbers that are stored in the computer of the car. This is to prevent unauthorised attempts to start the car as only the correct keys will be able.
This technology is thought to be more secure than the traditional car key since it makes it difficult for thieves to "hot wire" the vehicle to start it. However, it's not foolproof and thieves have discovered ways to evade and defy the system - which means that even cars equipped with transponder keys are not safe from theft.
