These tools are not available to the general public and are only used by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic skills, and a lot of time.
Other forms of car key programming are much easier and can be accomplished by anyone who is able to.

Modern automobiles require a key-programming method to initialize their vehicle's systems and to start the car. In a number of cases keys must be programmed by the auto locksmith or dealer.

The reason is because the new key has not been programmed to the car's system, and this could be quite expensive. It is recommended to have two keys that are compatible for your modern car so you can program the replacement key when required.
Keyprogrammers can recode the transponder chip on a new mechanical key or key fob. It can also clone data from an existing key to make duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer as well as a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car was manufactured within the past 20 years, then it contains a transponder chip within of it. This is a little plastic piece inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the chip in the key's transponder is the right one for your car.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to turn it on. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys appear like regular metal keys, but with a plastic cap. The chip is housed in the plastic portion of the key, and there are a few different kinds of cuts available on the keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still evade this system by using a specific device that intercepts the signal.
As you can see, there are quite a number of benefits to having transponder keys. This is something that all car owners should think about if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find a car in a parking space keys of today can also turn on the heated steering wheel or roll down all windows with a single press. Many of these extra features might seem useful, but they can also make it more difficult to keep the keys to your car.
Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. automotive key programming is encrypted to block other key fobs from stealing or modifying the signal.
There are several ways to program a key fob depending on the vehicle's make and model. It is possible to do this yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob the microchip inside sends a code to the car's radio that it is paired with. The receiver compared this information to the 'allowed' signals in the fob and then either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to operate.
Once the car is paired with a specific fob, it only accepts signals from that device. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This protects the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only work with cars that have original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the experience to design the replacement fob is a dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
