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 had grooves that corresponded to the internal parts of the ignition cylinder. As time went on and technology advanced as it did, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it difficult for thieves to open the vehicle.
The key chips in the keys have a unique serial number, which transmits signals to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are similar the car will begin to 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 for your vehicle, particularly when you use a transponder-based system.

Most modern cars are equipped with an entry system that is keyless. The system works by emitting radio signals which are detected by the keyfob. These signals are then compared with the correct code in the car's computer, and when everything is in order the car will be able to unlock. If the signals don't match, the car will not start.

This helps prevent unauthorized attempts to start the car, since only the right key can perform the task.
The technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars with transponder key are not immune to theft.
