These tools are not available to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. programming car keys requires expertise in soldering, electronic knowledge and a lot time.
Other kinds of car key programming are a lot simpler and can be performed by the average person. They are typically done using the onboard diagnostics port that can be accessed using a special key-fob-programming tool.

These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car was built in the last 20 years, it is likely that it has a transponder chip inside of it. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal is then amplified by the specific antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your particular car.
auto car key programmer is what prevents doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the key verifies that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like regular metal keys, but with caps made of plastic. The chip is contained within the plastic part 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 a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to 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 siren. This feature is designed to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still be able to escape this security system by using a special device to take over the signal.
As you can see, there are quite a number of advantages to having transponder keys. Every car owner must take this into consideration in order to safeguard their investment and decrease theft risk.
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, today's key fobs can also switch on a heated steering wheel or roll down all windows with just a single push. Many of these extra features may seem convenient but they could make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna within the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal.
There are several ways to program a key fob depending on your vehicle's make and model. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.
When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver that it is paired with. The receiver compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the information does not match the fob's information, the car won't be allowed to operate.
Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. This means that other fobs won't work with the vehicle even if they appear similar. This safeguards the integrity of the computer system in the car and prevents unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the knowledge to create an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
