These tools are not available to the general public and are only used by professionals. This type of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic expertise and a significant amount of time.

Key Programmers
Modern automobiles typically require a key programming process to start the system of the vehicle and allow the vehicle to begin. In some cases, the key will need to be programmed by an auto locksmith or dealer. The key may not work correctly or will not start the vehicle at all. This is because the new key hasn't been programmed into the vehicle's system. This can be quite costly. This is why it's a great idea to always have two working keys for a modern car and to have the replacement key programmed when needed.
A keyprogrammer is a device that can recode the transponder chip into the form of a new key fob or mechanical key. It also can clone data from an existing key in order to create 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 computers, and they also have an interface that works bidirectionally with the immobilizer system.
There are a variety of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes and colors. Some are inexpensive, while others are very sophisticated and could cost thousands of dollars. Certain models are specifically designed for certain types of vehicles and can offer advanced diagnostics for the vehicle's electronic systems.

They are cheaper than visiting a dealer but they aren't cheap. Before purchasing one make sure you research the seller. Some are not reliable and could cause damage to your vehicle.
car key programming
If your car was built in the past 20 years, then it contains a transponder chip within of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your specific vehicle.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the key also proves that you are the genuine owner of the vehicle. This helps to prevent car theft.
Transponder keys look like regular metal keys, but with caps made of plastic. The chip is housed in the plastic portion of the key and there are different kinds of cuts available on these 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 the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer in the car is able to recognize the signal as correct it will turn off the car immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and a siren. This is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A determined and skilled thief could still bypass this system using a special device that intercepts the signal.
As you can see there are quite few advantages to getting a transponder key. This is something that all vehicle owners should think about if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the car remotely, emit chirping sounds to aid in finding cars or turn on the heated steering wheel. A lot of these features may seem convenient however they could make it more difficult to keep the track of your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located in the middle of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are many ways to program a key fob, based on the make and model. It is possible to do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver it is paired with. The receiver then compares this information with the 'allowed' signals stored 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.
After the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs will not work with the vehicle even if they have the same appearance. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
