How to program a Key
Before the turn of the 21st century the majority of cars had basic key systems. The keys themselves were metal and had grooves that were connected to the internal components of the ignition cylinder. However, as time progressed and technology advanced and improved, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to open the vehicle.
The key chips that are in the keys have a specific serial number that transmits signals to the receiver inside of your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match 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 transponder-based.
If you want to learn how to program keys, you'll need certain equipment. You'll also need the blank key for your particular model and make. You can purchase these at an auto locksmith or a locksmith dealership, but it's essential to get the right ones. If you use a key that is for another model, it will not function.
To start the process, you need to insert the new key into the ignition and switch it to the "on" position. It is necessary to leave the new key in this position for about 10 minutes and 30 second.

The signals are compared to the code stored in the car's computer and if everything is well the car will be able to unlock. The car won't start when the signals aren't the same. If your key fob isn't already programmed, it is possible to follow several steps to program it.

This energy is absorbed into the chip and it transmits the radio frequency signal, which includes an identification code that matches with the unique serial number of the car's computer system. This will prevent any an unauthorized attempt to start the car, since only the right key can do so.
It is believed that this technology will be more secure than traditional car keys because it makes it much difficult for thieves to "hot wire" an automobile and get it started.
