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 featured grooves that matched the internal parts of the ignition cylinder. As time passed and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to protect against theft. Key systems are also referred to as transponder keys or chips keys, are designed to make it more difficult for thieves to start an automobile.
The key chips in the keys have a unique serial number that transmits a signal to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are similar the car will begin to start. If the codes don't match, your car will not even start. This is why you should keep an extra car key, especially if your system is based on transponders.
You'll need special equipment to be able to program keys. You'll also need a blank key for your particular model and make.

This energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that matches up to the unique digital serial number in the car's computer system. This prevents unauthorized attempts to begin the car, as only correct keys will be able.
This technology is believed to be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" an automobile and start it. But it's not foolproof, and thieves have discovered ways to evade and thwart the system so that even cars with transponder keys aren't protected from theft.
