How do you program a key
Before the turn of the 21st century the majority of cars had basic key systems. Keys were made of metal and incorporated grooves to correspond with the internal parts in the ignition cylinder. As technology advanced, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.
The key chips come with a unique serial code that transmits a message to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, your car will begin to start. If the codes don't match, then your car will not even start. This is one of the main reasons to keep a spare key for your vehicle, particularly in the case of transponder-based systems.

The chip absorbs this energy, and then sends a radio frequency signal that includes an identification code. The code is matched to the unique digital serial numbers of the computer of the car. This helps prevent unauthorised attempts to start the car because only a valid key can do so.
It is believed that this technology will be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" an automobile and get it started. It's not foolproof and thieves have discovered ways of tricking and defeating the system. So even cars with transponder key are not protected from theft.
