How to program the key
Before the turn of the 21st century, the majority of cars had basic key systems. Keys were made from metal and incorporated grooves to match the internal components of the ignition cylinder. As time passed and technology improved and improved, car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to get into the vehicle.
The key chips have a unique serial code that transmits a message to the receiver inside your car. The signal is compared with an identifier in the car's computer when it is received. If the codes match, your car will begin to start. If the codes don't match, your car will not even start. This is one of the main reasons why you should always keep a spare key on your car, especially when you use transponder-based systems.
You'll need special equipment to learn how to program keys. You'll also require a blank key for your particular model and make. They can be purchased from a dealership or by locksmiths, but you must make sure they're the right ones. If you use a key from another model, it won't work.

This energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that matches with the unique serial number that is stored in the car's computer system. This is to prevent unauthorised attempts to start the car, as only proper
reprogramming keys for cars will be able to do so.
The technology is believed to be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" an automobile and get it started.
