How to Program a Key
Prior to the beginning of the 21st century most cars used basic key systems. The keys themselves were metal and featured grooves that matched the internal parts of the ignition cylinder. As technology advanced, more and more car manufacturers began to combine physical and electronic protocols to stop theft. Key systems, also known as transponder keys or chips keys are designed to make it difficult for thieves to start a vehicle.
The key chips inside the keys have a unique serial number, which transmits a signal to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are similar the car will begin to start. If the codes aren't compatible, your car won't even start. This is why you should keep an extra car key particularly if your system is based on transponders.
You'll require special equipment to be able to program keys. You'll also require the blank key for your specific make and model. They can be bought at the dealership or through a locksmith however, you must be sure they're the right ones. If you use a key for another model, it won't function.
To begin the process, simply insert the new key into the ignition and turn it to the "on" position. You'll need to keep the new key in this position for around 10 minutes and 30 second.

The newest models also allow remote management and configuration and are cloud-based.
Most modern cars are equipped with the keyless entry system. To accomplish this it emits radio signals that are detected by a specific key fob. These signals are then compared to the correct code stored in the car's system, and if everything is in order the car will be able to unlock. The car won't start if the signals are not identical. There are several steps you can follow to program your new key fob, if it's not already programmed.

When the key is placed in the barrel of the ignition lock and turned to the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. The chip absorbs this energy, and then transmits a radio frequency signal that includes an identification code. This code is in line with the unique serial numbers that are stored in the computer of the car. This helps prevent an unauthorized attempt to start the car since only the right key can perform the task.
This type of technology is thought to be more secure than a conventional car key since it makes it harder for a thief "hot wire" the vehicle to start it.
