These tools aren't generally available to the public and are only used by professionals. This type of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.
Other types of programming car keys are much simpler and can be performed by the average person.

This is why it's a good idea to have two keys that work for modern vehicles, so you can get the replacement key programmed if needed.
A keyprogrammer can reprogram the transponder chip of an entirely new mechanical key or key fob. It is also able to copy the data of an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with a computer. They also feature a bidirectional user interface for working with an immobilizer system.

Transponder Chips
If your car is made within the last 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip in the key is the right one for your specific vehicle.
This is what stops hot-wiring or tampering with the vehicle's ignition system to start it. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a regular cut, a laser cut (also called a sidewinder), or a 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 will be received by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.
It is evident that the transponder is an excellent option. All car owners should consider this if they wish to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find a car in a parking space, today's key fobs can also activate a heated steering wheel or roll down all windows with a single click. A lot of these additional features may appear convenient, but they can also make it harder for you to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. The frequencies are transmitted by a small antenna in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in a variety of ways depending on the model and make of your car. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or additional one.
When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is paired. The receiver compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car is paired with a particular fob, it will only accept signals from that specific device. Other fobs will not work with the car, even though they appear identical. This ensures the security of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by the consumer without the need for a dealership.
