How to program a key
The majority of cars had basic keys systems until the turn of 21st century. The keys themselves were metal and featured grooves that matched the internal components of the ignition cylinder. As technology improved, more and more automobile makers began to combine physical and electronic protocols to avoid theft. These key systems are known as
transponder key programming keys or chip keys and are designed to make it difficult for thieves to get into the vehicle.
The key chips that are in the keys have a unique serial number that sends an electronic signal to the receiver inside 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 identical then your car will begin. If the codes aren't compatible, your car will not even start. This is why it is important to keep a spare car key, especially if the system is based on transponders.
If you're interested in learning how to program keys, you'll need some special equipment. You'll also need to purchase an uncut key that matches your specific model and make.

This energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that matches with the unique serial number of the car's computer system. This helps prevent an unauthorized attempt to start the car as only the correct key can do so.
