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 were connected to the internal components of the ignition cylinder. As technology improved, more and more car manufacturers began to combine physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it difficult for thieves to open the vehicle.
The key chips inside the keys have a specific serial number, which transmits a signal to the receiver in your car. The signal is then compared to the computer of the car when it is received. If the codes match, then your car will begin to start. If not, it will not start at all. This is the reason you should keep a spare car key, especially if your system is transponder-based.

Most modern cars come equipped with a keyless entry system. To accomplish this the car emits radio signals which are picked up by a special key fob. The signals are then compared to the correct code in the car's computer and when everything is in order the car will start to unlock. If the signals do not match and the car does not start. If your key fob has not been already programmed, you can follow several steps to programme it.

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that corresponds with the unique serial number in the car's computer system. This will prevent any unauthorized attempts to start the car, because only a valid key will be able to do so.
This type of technology is thought to be more secure than a traditional car key, as it makes it difficult for a criminal to "hot wire" the vehicle to start it.
