How to Program a Key
Before the turn of the 21st century the majority of cars utilized basic key systems. The keys were made of metal and featured grooves that correspond to the internal parts in the ignition cylinder. As time passed and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to start an automobile.
The key chips inside the keys have a specific serial number, which transmits a signal to the receiver in your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes match 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, especially in the case of transponder-based systems.

Most modern cars come equipped with an entry system that is keyless. To accomplish this, the vehicle emits radio signals which are picked up by a special key fob. The signals are compared to the code that is stored in the computer of the car and, if all is in order the car will start to unlock. The car will not start if the signals are not the same. There are several steps you can take to program your new key fob, if it's not already programmed.

The code is matched to the unique digital serial numbers in the computer system of the car. This is to prevent unauthorized attempts to begin the car since only proper keys will be able to do so.
This technology is thought to be more secure than a conventional car key since it makes it harder for a thief "hot wire" the vehicle and start it.
