These tools aren't generally accessible 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 kinds of key programming can be carried out by anyone. These are usually done by using the diagnostics port on the car, that can be accessed using a special key-fob-programming tool. This method can be done by a trained locksmith with the help of an online guide or the vehicle's owner manual.

Key Programmers
Modern automobiles require a key-programming process to initialize their vehicle's systems and to start the car. In some cases the key will have to be programmed by an auto locksmith or dealer. This is because the key might not function properly, or it will not start the vehicle in any way. This is because the new key has not been programmed to the automobile's system. This can be very costly. It is recommended to have two keys that work with your current car so you can program the replacement key when needed.
A keyprogrammer is a tool which can reprogram the transponder chip into an entirely new key fob or mechanical key. It is also able to copy data from an existing key to create duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.
There are a number of different kinds of keyprogrammers that are available, and they come in all shapes and sizes. Some keyprogrammers are cheap, while others may cost thousands of dollars. Certain are designed for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.
If you're looking to program an entirely new key for your vehicle, consult the owner's manual to find out how. Certain manufacturers employ proprietary technology that ensures the dealership is the only entity that can make new keys, however other manufacturers make it fairly easy for anyone to accomplish it themselves.

These are less expensive than visiting a dealership, but they're still expensive. Before you purchase one, do some research on the seller. Some are not reliable and may damage your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, chances are it has a transponder inside of it. It's a tiny plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then absorbed by the special antenna that is fitted around the ignition barrel of your car. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for your particular car.
This is the reason why from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip in the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys appear like normal keys but have caps made of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different kinds of cuts available on these keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will be received by the chip and cause it to transmit a signal back to the car. If the car's computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still bypass this system with a specially designed device that intercepts the signal.
You can see that a transponder is a great option. All car owners should consider this if they wish to protect their investment and minimize theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking space, today's key fobs can also switch on a heated steering wheel, or open all windows with a single button push. A lot of these additional features might seem useful but they could make it more difficult to keep track of your car keys.
automotive key programming are able to communicate with each other and with the car through radio frequencies which are transmitted by an antenna that is located in the center of the key. The transmission is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
There are many ways to program a key fob based on the vehicle's make and model. It is possible to do this yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button it transmits an informational code to the car's radio that it is paired with. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.
Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they appear similar. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. Some aftermarket fobs, usually those for older models with less sophisticated systems can be programmed with out the need for a dealer.
