These tools aren't usually available to the public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.

Key Programmers

car key programmers. In a number of cases keys must be configured by the dealer or auto locksmith. The key might not function properly or not start the car in any way. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. It is recommended to have two keys that work with your current car so you can program the replacement key when needed.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It can also clone the information from an existing key which allows duplicate keys to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

They are cheaper than visiting a dealership but they aren't expensive. Before purchasing one, do some research on the seller. Some aren't reliable and may damage your vehicle.
Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder chip inside 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 code unique to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around the ignition barrel of your vehicle. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started through either hot-wiring or by tampering. The chip in the key also proves that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys look like normal keys but they have caps made of plastic. The chip is contained within the plastic portion of these keys. There are a variety of cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received 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 car does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A determined and skilled thief could still bypass this system using a special device that blocks the signal.
As you can see there are quite a number of advantages to having transponder keys. This is something that all car owners should think about if they want to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate a car in a parking space Key fobs today can also activate the heated steering wheel or open all windows with a single button press. A lot of these additional features may seem convenient however they could make it difficult for you to keep track of your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted via a small antenna located in the center of the key. The communication is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in different ways based on the model and make of your car. You can sometimes do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits signals to the receiver in the vehicle with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob, and then opens or locks the car door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.
When a car is connected with a specific fob, it will only receive signals from that specific device. As a result, other fobs will not work with the vehicle, even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the experience to design the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically those for older models that have less advanced systems can be programmed without the need for a dealer.
