How to program a Key
Before the turn of the 21st century, the majority of cars utilized basic key systems. Keys were made from metal and had grooves to match the internal components of the ignition cylinder. As technology advanced, more and more automobile makers began to combine electronic and physical protocols in order to prevent theft. Key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to steal an automobile.
The key chips contain an unique serial number which transmits a signal to the receiver inside your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match, your car will start. If not, it will not start at all. This is one of the main reasons why you should always keep a spare key in your vehicle, especially in the case of transponder-based systems.

Modern cars come with keyless entry systems. To enable this feature, the vehicle emits radio signals that are detected by a particular key fob. The signals are then compared to the correct code stored in the car's system, and when everything is in order the car will start to unlock. The car will not start when the signals aren't identical. There are a variety of steps you can take to program your new key fob if it isn't already programmed.

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that corresponds with the unique digital serial number that is stored in the car's computer system. This is to prevent unauthorised attempts to start the car since only proper keys will be able to do so.
It is believed that this technology will be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" the vehicle and get it started. However, it's not foolproof and thieves have found ways to deceive and defeat the system - which means that even cars equipped with transponder keys aren't protected from theft.
